To a lot of consumers, home theater installation can be a mind
boggling concept. Unfortunately for some, it can also be wallet
draining. So it comes as no surprise that the average consumer would try
to find ways to save any money they can. The normal place most try to
save is home theater product itself, trying to go with entry level
equipment expecting high end performance which often leads to
dissatisfaction and high returns. Another unfortunate place home owners
try to cut corners is on the actual install itself. There are a few
notable reasons why this is a choice that saves money now but could end
up costing more in the long run.
New construction homes are seeing a lot more than just electrical
wiring ran. Surround sound wiring and pre-wiring for a HDTV above the
fireplace are common place now. It is a great addition to your home
during construction or renovation for immediate or future use and almost
always adds resell value to the home. Who doesn't want the experience
of theater quality sound in their home? As more and more home owners
request this service, more and more contractors are becoming adept to
world of home theater.ss
The place where the two worlds intersect is a notable place where
homeowners try to save money on their Austin Home Theater Installation.
The contractor offers a bundled "home theater installation" price to run
speaker and video wiring and connect it all. The average consumer would
think to themselves that the walls are down anyway and I am trusting
this man to construct my wall so why not let him connect what he is
already running for me? Why spend the extra time and money looking
elsewhere for a home theater install team to come and do the same thing?
A penny saved is a penny earned as the saying goes.
This is where it is wise to stands back and thinks about long term
results. The contractor has been doing his job for twenty-plus years in
most cases. He can build a house and make it livable, but does this mean
he can set up my new home theater that I spent my hard earned money on?
My new Smart LED HDTV lets me surf the internet wirelessly on it. My
new surround sound receiver lets me multi-zone whole home audio.
With what I am paying this person for my home theater installation,
is he going to make sure I am getting everything out of the
four-thousand dollar cinema system I purchased, or is he going to simply
plug it in and turn it on?
Sadly, the ladder is usually true. There is no disrespect intended,
but twenty-plus years in one field do not make you a viable expert in
another. There is a lot more to your entertainment system than an on and
off button. Are the speakers going to properly be calibrated for phase,
crossover, distance and EQ to have the best sound for the size of your
room and location of the listener? Is the receiver going to be setup to
properly control multiple zones of sound so that you can enjoy the game
inside while your wife enjoys the radio outside? Are your audio sources
going to properly be set for PCM or Bit stream in the receiver to
receive the best quality sound from each of them? Probably the most
important question of them all; Will you know how to properly work your
entertainment system when installation is complete? With the contractor
the answer is usually a no. With the home theater installer, the answer
will always be a yes.
The Austin Home Theater installer knows the equipment inside and out.
He keeps up to date on what's new in the audio/video world so he can
properly recommend the right equipment for family. He knows the
capabilities and limitations of your system. He knows the right settings
for your speakers so your surround sound receiver has to do less work
and get better results. He knows the best settings for your HDTV for the
type of room it's in. To put it bluntly, the installer knows home
theater installation.
The place where the two worlds intersect is a notable place where
homeowners try to save money on their Austin Home Theater Installation.

LCD Monitor Problems - Easy Way To Repair Itasd
Today's article talks about repairing the CMV 19" LCD Monitor
problems model CM-922D. The complain was no power as what the customer
told me. This power supply was not built into the circuit thus it need
an external power adapter to power it up. The input to the hdmi monitors
is 19V with 3.1 Amp from the adapter. Since the complain was no power,
we have to test it out to check if the power adapter is at fault or the
LCD Monitor.
The ac supply was plugged in to the power adapter and I could see the power LED was lighted up. Checking the output voltage of the power adapter I got about 19 volts which is good. Even though the LED has lit and correct output voltage, this doesn't mean that the power adapter can maintain when there is a load (the portable hdmi monitor) connected to it. I once came across a Compaq 17" LCD Monitor that have a precise output voltage from the power adapter but when connected to the Monitor, the display appeared for a fraction of a second before shutting down. Usually in this case, your experienced would tell you that it could be the inverter circuit are faulty or the lamps have problem. You would be surprised that the actual cause of the shutdown was due to the power adapter. It can't sustain the output voltage when there is a load on it.
This kind of fault was normally due to a bad filter capacitors located at the output of the secondary circuit. If you have ESR meter, you can actually locate the defective electrolytic capacitors fast. If you don't have the meter, just direct replace the caps. As mentioned in my previous repair articles, to confirm if the power adapter is truly working or not you need a light bulb to act as a load. Make sure the power no touch screen doesn't blink whenever the light bulb is connected. Even if it blinks one time, this proves that the regulation is not good and need to be check entirely. In the above china made LCD Monitor, the power adapter work perfectly fine!
Since I have already confirmed that the power adapter is good, my focus now was on the LCD boards. Removing this cover was very easy and you can easily access to the board when the metal casing was removed. The first thing that I checked was the SMD fuse located in the main board. If the fuse opens then there would be no supply to the ADC/SCALAR and the CPU IC thus the power LED would not light! Checking this SMD fuse was rather simple as the method of checking it is the same like a normal fuse. Use either an analog or a digital meter set to ohms range or continuity check. You can check the fuse while it is still in circuit. Yes, the fuse was found to be open circuit.
Now there is one question that needs to be answered by us. What makes the fuse to go open circuit? Well from what we have known about electronic repair, there are three possibilities as why a fuse opens circuit. First, the fuse can become open circuit due to its lifespan. Some fuses can last for many years while some only couple of years. In other words, the life span of a fuse depends on the qualities of the materials used. Secondly, the external factor such as a surge causing the fuse to open circuit in order to protect the main board. Thirdly, the main board itself have problem (such as a shorted IC's and other electronic components) that caused the fuse to open circuit.
If the LCD Monitor problems falls in the first and the second categories then replacing only the fuse will definitely solve the problem. However, for this LCD Monitor, replacing only the fuse didn't work at all and the fuse open circuit again. You have only two choices to solve this kind of problem. First you can use an external regulated power supply as explained in my previous repair articles and connect the negative output of the power supply to ground and the positive to the fuse (the line that leads to other circuitry) in order to detect the short circuit. Slowly vary the output voltage and monitor the current drawn. Once the current drawn about a amp or two, now place your finger to any electronic components in the main board. If you found any components that get very hot then that is the cause of the short circuit.
In this article, I'm going to do it differently to detect the short circuit. Are you ready? Now instead of replacing the fuse with the exact rating which is 3 amperes, I replaced it with a 5 amperes fuse. The purpose for me to put the 5 amp fuse instead of the 3 amp fuse was because "if the fuse doesn't blow then the component that have short circuit would blow". Do you get the idea? Three things can happen when you use this way to force out the culprit. First the power adapter may shut down due to heavy current draw from the main board. Second, the short circuit electronic components (either be a IC, diode, capacitors, transistor and etc) will get hot and you can quickly locate it easily by touching them. Remember don't on it for too long otherwise if the shorted components get too hot it will go open circuit and now you will have a hard time to locate the fault. Third, you may hear a pop sound and spark from the shorted component. Trace from where the spark came from and you can easily identify the location and sometimes to the actual component that generate the spark.
For the above LCD Monitor, I actually saw a small spark at the top part of the main board once the power input jack was connected. It prompted me to the exact location and when I check the SMD ceramic capacitor (that generated the spark underneath it) with analog meter set to X 10 K ohm range; it actually developed a slight short circuit. Replacing only the fuse and the SMD ceramic capacitor solved the no power problem in this 19" LCD Monitor. This Monitor uses the inverter IC (OZ960G), A1084-25CM (2.5 volts voltage regulator), AMC1117-3.3 (3.3 volts voltage regulator), ADC IC (MST8136B) and CPU IC (MYSON MTV312MV64).
Conclusion-There are always options as to which methods that you want to use to detect the short circuit. If you prefer the latter one, then I suggest you to take some photo shots first before anything really burnt out beyond description. With the photos, at least it will give you some hints of what the components might be or even the part numbers. Well, there's always an interesting way to solve electronic problems and this is one of the reason that I like electronic repair so much because you can always act as a detective to find out the culprit-real satisfaction! Oh! By the way, you can use the above method to any other electronic equipment and it is not limited only to problems repair. Have a great hunt my friend!

Onkyo 608 - A Home Theater Star
When purchasing a home theater, don't stop at just a big-screen
HDTV and a Kinter MA-700 Amplifier player. You're not going to have a truly great
cinema experience until you have a great surround-sound audio system.
That's more than just a strong bass sub-woofer; you'll also want
multiple speakers to envelope you in the audio experience.
The Onkyo 608 fits the bill nicely, offering the audio quality and long list of features you'd expect only in much more expensive units. It's still called a "receiver" from the old stereo tradition where the audio amplifier featured an AM/FM receiver. This Onkyo receiver adds audio surround-sound processing, video switching, and a lot more.
5.1 + 3 = 7.2?
You're may be familiar with 5.1 channel audio systems. They add 4 more speakers beyond the old stereo systems, for a total of 6 speakers. Starting with the 2 stereo speakers, add a center-speaker for a more solid sound. Then two (left and right) more speakers in the rear behind the listener so they're surrounded by sound. Finally add a sub-woofer for power at the really low frequencies so important to movie special effects. Now you have a 5.1 channel surround-sound system.
A 7.2 channel system adds 3 more speakers. First, there's a second sub-woofer. Now the really low stuff is in true stereo. The other 2 speakers are usually used as extra-wide speakers in the front for an even bigger cinema effect. With a 7.1 channel system, you don't get the second sub-woofer.
The Onkyo Topping TP21 can also process the audio for placing the 2 additional speakers higher up in the front for a more 3-dimensional effect. Or (with the 608) you can use those speakers as a stereo in another room. You can even feed them a separate audio source than that of the main room. Yep, the 608 can feed 9 speakers, with several different options.
Audiophile Sound
This home theater audio system isn't just for movies and games. It also receives very positive reviews and comments for it's sound quality and power - 100 watts per channel (though a bit over 700 watts total).
It's also packed with audio processing capabilities. It features Dolby TrueHD, and can even improve the sound from MP3 and other compressed sources. The Onkyo 608 can automatically adjust equalization to precisely tune the sound to your particular room, and even includes a microphone. It can also automatically adjust tone for different volumes.
Audio-Video Switching
With receivers like the 608, you no longer need switchers or converters to connect all the components of your home theater. With 6 HDMI inputs, you should be able to handle as many digital video and audio sources you're ever likely to have. Plus video and audio get switched together with a single remote-control command.
All video inputs are converted to 1080p resolution for the best viewing and no resolution changes when you switch sources. This isn't flawless, however. If you're watching slower video, such as the 30 frames-per-second you find on some cable channels, you'll get a momentary flicker if there's a data dropout on the input. The 608 doesn't process this away, although many HDTVs will do this themselves.
Summary
Despite some special-case video glitches, owners love this receiver for movies, music, gaming and more. The Onkyo 608 is a modestly priced surround-sound receiver that offers the features and quality of much more expensive equipment.

Explanation of Home Theater Speaker Systems Types
If you want to get better quality of home theater experience, then one of the best components are home theater speakers.
Let us first discuss what a home theater is:
It is used to create a movie theater experience at our home only. It is basically a combination of two media types, video and audio.
The 5.1 set up is most common configuration for home theater speaker systems. Also the 5.1 set up, of it includes a right front channel, a left front channel, and a center channel.
Right Channel Speaker
Towards the right of TV is the front right channel and in most of the cases loudspeaker handles large signal range. This one is extremely powerful and fills up the room with high quality sound.
Left Channel Speaker
The left channel speaker is also important and works in stereo with the right channel. These are always sold in pairs and are quite powerful.
Center Channel Speaker
This one is located either underneath the TV or above the TV. It consists of a single speaker that handles midrange sound. These are usually rectangular in shape and are magnetically shielded.
Subwoofer
These are meant for low frequencies which travel in all directions and are Omni- directional and are placed anywhere within the room.
Surround Sound Speaker
Surround sound channel speakers are the two speakers which have been placed behind viewer. These are meant to give feel of a video environment and are commonly referred to as satellite speakers. These can be hanged on wall brackets or small stands. It has been noticed that if there is any large room, they can be paired with three surround sound channel speakers.

Regarding Home Theater Audio Receivers
When contemplating how to put together a home theater system, one
should not forget a crucial component to the audio and visual
experience. Home theater audio and video are controlled by a receiver
which is the central unit where the inputs and outputs of the home
theater are based.
A home theater receiver combines the functions of three components. First, a tuner for AM and FM, in some cases high definition radio or Sirius Satellite or Internet radio. Second, a preamp that controls the audio or video source selected - Blu-ray play, DVD player, iPod etc. Last, a built in multi-channel amplifier that sends the surround sound signals to the speakers and also supplies power to the speakers.
The modern audio visual receiver (AVR) is a complex device, perhaps one of the more complex electronic devices in the home. It has a computer, amplifiers, audio signal processing chips, signal converter chips. Many AVRs have video processing chips as well. The main circuits in an AVR are: Power supply; Processor; Analog Audio; Digital Audio; Analog Video; Digital Video; Amplifier.
Each of these groups can be one or more circuit boards, or some could be combined onto a single circuit board. Care must be taken in the design such that circuits don't interfere with each other. There's also the need to deal with physical needs such as connector placement and air flow for proper cooling.
Stereo receivers have two channels of amplification, while AV receivers may have more than two. The standard for AV receivers is five channels of amplification. These are usually referred to as 5.1 receivers. This provides for a left, right, center, left surround and right surround speaker to be powered by the receiver. 7.1 receivers are becoming more common and provide for two additional surround channels, left rear surround and right rear surround.
AV receivers usually provide one or more decoders for sources with more than two channels of audio information. This is most common with movie soundtracks, which use one of a variety of different types of encoding formats.
As the number of playback channels were increased on receivers, more decoders have been added to some receivers. For example, Dolby Labs created Dolby Pro Logic IIx to take advantage of receivers with more than five channels of playback. With the introduction of high definition players like Blu-ray Disc and HD DVD, even more decoders have been added to some receivers. Dolby TrueHD and DTS-HD Master Audio decoders are available on many receivers.
All this information can be a lot to take in, however many web resources are dedicated to receivers alone. When choosing to revamp or build from scratch a home theater audio and video system, investigate the receivers offered to make the best choice for your personal theater needs
