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.

HOW TO ENTER SERVICE MODE TO RCA & GE TELEVISIONS

HOW TO ENTER SERVICE MODE TO RCA & GE TELEVISIONS - Universal Remote Control Set-up Codes



SERVICE MODE ENTRY & ADJUSTING PARAMETERS
For most models after 1994:
  • Turn the TV on.  
  • Press & Hold down MENU and hit POWER and Volume +.
  • Now you're in the service mode, looking at parameter 0.
  • It will say: P00 V00
  • Use the Volume + key to change the value (V number) to 76. This has to be set before you can do anything else; it's sort of a password.
  • Once P00 is set to V76 you can use the Channel ▲/▼ buttons to select from the first 12 parameters.
  • P13 is another password – set to 77 to get higher parameters.
  • Depending on the model, another one a couple of dozen parameters up will require a password of 78.
  • This varies by model but you will know when you have found it because you won't be able to advance past it.
  • The first parameter, P01, is probably the quickest and easiest to work.
  • It is the Horizontal Frequency control. When you select it, the TV will lose horizontal sync.
  • Turn it all the way down or all the way up with  [►V+]  or [◄V-] and then get out of set-up (if the TV hasn't shut itself off) then switch OFF the power button.
