REPAIRING AND NOT THROWING AWAY

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.

The aspect ratio of the screen is wrong (picture vertically expanded) when you play a wide picture even though you set “TV DISPLAY” in the SETUP menu to "16:9".
• If you connect the system with the SCART cable, connect directly to the TV. Otherwise the auto switch function of the aspect ratio for the TV may not work.
• If the TV is not connected with a SCART cable to the HS, or if the auto switch function does not work you should turn the TV to "16:9" (if possible with your TV).
• Depending on the TV, you may not be able to change the aspect ratio. In that case (TV not adjustable to 16:9) do not select "16:9" in the TV Display. Then, no change of the aspect ratio is needed.
The volume goes down automatically and cannot be increased.
• The internal temperature is too high. Wait approximately one minute for the amplifier to reach normal working temperature.
The subtitle language cannot be changed when you play a DVD.
• Multilingual subtitles are not recorded on the DVD.
• Changing the language for the subtitles by the Subtitle button on the remote or the Subtitle line in the Player Menu is prohibited on the DVD. In that case the subtitle language must be selected by the main menu on the DVD.
The subtitles cannot be turned off when you play a DVD.
• Depending on the DVD, you may not be able to turn the subtitles
