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.

RCDW500C – Sony compact disc recorder – circuit diagram – self diagnosis US and Canadian Models

Sony RCD W500C  US Model Canadian Model COMPACT DISC RECORDER - Self diagnosis - Program setting - Circuit diagram
Self-diagnosis Function
When the self-diagnosis function is activated to prevent the player from malfunctioning, three character service numbers in a combination with a message appears in the display.
C12/ Cannot Copy:  You are trying to record a disc that cannot be played back in DECK-A or with an external device, such as CD-ROM or VIDEO CD.
• Remove the disc, and then insert a music CD for playback.
C13/ Rec Error:  Recording has not been completed successfully because of vibration.
• Relocate the unit in a place free of vibration and restart the recording again.
The disc you try to record is excessively dirty (such as oil stained or finger marked) or scratched. Or the disc is not normal.
• Replace the disc with another one and restart the recording again.
C14/TOC Error:  The unit did not read the TOC information.
• Insert other discs.
C41/Cannot Copy:  The sound source you are trying to record is a copy of commercial music software. Or you are trying to record on a CD-R/CD-RW digitally.
• Because of the restriction of the Serial Copy Management System, you cannot record a copy of commercial music software.  Neither can you record a CD-R/CD-RW digitally.
C71/ Din Unlock:  If this message is displayed momentarily, this is not an error. It is caused by the digital signal during recording.
During recording of a digital sound source, the connecting cable has been disconnected or the player of the sound source has turned off.
• Connect the cable or turn on the digital player.
LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.  The emission check enables continuous checking of the S curve.
