Odd GE TV EEPROM problem.

The menu problem with the wrong EEPROM is pretty normal. Get the correct EEPROM and it should work ok. You should power the set on with the new correct EEPROM installed, then swap the original bad EEPROM in (with the set running) and enter service mode to write down all the tuner settings.

That procedure has never failed me. I've seen some very strange symptoms when the EEPROM was corrupted. I had one that wouldn't come into horizontal sync, no matter how I adjusted the horizontal frequency. A new EEPROM fixed the set. Andy Cuffe

You can also just get a reader for about $30 or less and transfer the data from the old EEPROM to the new one without having to do a hot swap. You can even use a good EEPROM from another model if it is the same type. Fixed lots of RCAs this way without having to inventory so many EEPROMS or ordering them. I also keep a library of EEPROM data for various chassis and models in case I get one where the data is corrupt.

Thanks guys for help! I did install a good used EEPROM from a working set, & it still locked up, or shut down, when pressing the menu button a couple of times! A Tech buddy of mine had the exact same problem, & never got it fixed, even after replacing the EEPROM, & both Micro's. You mean, replace the EEPROM, while the TV is on? Thanks, Dani.

Where are you finding such a cheap EPROM programmer?

Also, how do you copy just the alignment data without also copying the corrupted firmware to the new EEPROM? Andy Cuffe

Lots of times, especially on the 185 chassis for some reason, the firmware is fine and the EEPROM itself is bad. Copying everything saves a LOT of time. We once stocked lots of RCA EEPROMS but not anymore. In fact I have been recycling the old unused inventory by copying good data to the chips from different sets if the EEPROM type is the same. If there is corrupt data I know of no way to extract the alignment info without getting the set cranked up and recording it manually. Someone may know the layout of the data but I don't. Somewhere I remember seeing someone who claimed to have identified the location of the bad data that caused the audio muting problems on the 177 chassis, but I can 't find the info and have never bothered to sort out the data myself.

You can find a cheap programmer here:

I have a couple of dozen data files for various sets if anyone needs them. Someone else had some on a web site a while back so if you search you can likely find them.

And if you need more capability

These are for sale on ebay regularly as well. I have one and it handles every type of ROM chip I've thrown at it yet and I think it was only $40 or so. These things are really much cheaper than they used to be.
