REPAIRING AND NOT THROWING AWAY

REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

Richtige Fernseher haben Röhren!

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.

  • Use a pin φ 4mm or less.
This picture shows the unit upside down. The eject lever is pointed by the arrow.  The lever is thin so aim the narrow area carefully.
When removing the flat wire PS01, connecting the optical pick up and the CD decoder board, short-cut the two lands pointed by the arrow with solder. Otherwise the laser diode may be damaged by static electricity.
CD Decoder Board (PS01) Repair
When Repairing the CD decoder board PS01, you can fix the board on the loader unit as shown in the picture below with the flat wires that are provided as service parts.
Disk Tray Open/Close Speed Adjustment
  • Open/Close speed of the tray can be changed.
  • When vibration occurs upon tray open/close and some unusual behavior happens, change the tray speed to stop vibration.

Vibration on Disc Tray Open / Close
