1996 RCAColorTrax TV Service Menu

[JohnCT]

The service menu isn't going to help you. Even if you can get just the vert and horiz readjusted, I can promise you that there are parameters all over the place that are kludged.

You've got a corrupt eeprom caused by bad grounds in 1) the tuner, 2), the LV regulator heatsink ground tab and 3) the horiz output heatsink ground tab.

When these used to come in, I wouldn't even open them up. I'd call them a couple of hours later and give them the estimate, then repair and upgrade the chassis. I would do between 5 and 10 of these a day including several from other servicers.

Towards the end of their run, that series of chassis also had two electros in the power supply that had to be changed as well.

I don't know if anyone on youtube has the procedure videoed, but the tuner grounds must be done immediately along with the heatsink ground tabs. If you were to install a new eeprom, or realign the original eeprom, it would end up being corrupted in minutes.
