In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

Since our ears do not hear directional sound at the low frequencies where the sub-woofer operates, it will have good performance from just about any location in your room. However, the best bass reproduction is likely to be heard when the sub-woofer is placed in a corner along the same wall as the front left and right speakers. you can experiment with sub-woofer placement by temporarily placing it in the listening position and playing music with strong bass content. Move around to various locations in the room while the system is playing and listen until you find the location where the bass performance is best. Place the sub-woofer in that location.

The front speakers should be placed the same distance from each other as they are from the listening position. They should be placed at about the same height from the floor as the listener’s ears will be. They also can be angled toward the listener.
The center speaker should be placed slightly behind (farther away from the listener) the front left and right speakers. Its center should be no more than 2 feet (61cm) above or below the tweeters of the front left and right speakers. If you have a CRT television, it may be convenient to set the center spea ker on top of the television set.
The two surround speakers should be placed slightly behind the listening position, facing each other and, ideally, should be 5–6 feet (1.5m–1.8m) from the floor. An alternate location would be on a wall behind the listening position, facing forward. The surround speakers should not call attention to themselves while they’re playing. experiment with their placement until you hear a diffuse, ambient sound accompanying the program material heard from the front left and right and center speakers.
