RCA D52W20 fails to start

I just did a little bit more research and found the service manual. On the link it said "There have been reports of EEPROM being scrambled after geometry adjustments have been made."

I'm afraid that sounds like what happened to me, what do I do?

here's a link to the service manual.

Alex best call a shop who has the chipper checker and tell them what you have done.

Art,

though my knowledge in television electronics is not as far reaching as it is in the PC realm, I'm far from an "average" consumer. I know my hardware, and I knew the risk I was taking as soon as I went into that menu. In my defense, curiosity did get the best of me when I entered the geometry menu, but I did not save any settings, I barely even moved a slider in any direction. So I'd love to know how the same result wouldn't have happened to a professional.

I'd appreciate some useful input from you, or none at all. Your opinion had nothing to do with the current situation.

As someone said before, a service company with the chipper check box and software can write defaults back to the eeprom in a matter of moments. This is most likely all you need. It is also at this point probably the only way to fix the set since it will not start normally for you to manually enter the defaults.

Thank you ampdoc and kip.
