GE TV# 27GT62616 Issues

Problems like this tend to be caused by bad solder joints or other bad connections. They are affected by environmental conditions like temperature so tend to come and go. Gently whacking the TV would probably make it come or go as well.

It's repairable but continuing to use it in this state may result in more serious and expensive problems.

Problem most likely in on-board tuner assembly, under shield where cable connector is. Various connections tend to go bad and cause varied symptons.

Sam, Your whacking solution worked great. I took the set outside and blew 8 or 9 years of dirt out of the inside, but now the picture is whiter. It's far from unwatchable, but I found the difference interesting. Any ideas what happened? Thanks.

This is only an interim solution:

A more permanent fix would involve reflowing the solder at dry joints, probably in the power supply and line stage.

The whacking is just a diagnostic tool, the problems will come back and it needs to be repaired properly to avoid further damage.

It's possible you accidently touched an internal pot, perhaps SCREEN/G2 on the flyback.

Since you will still have the intermittent problem, have it looked at by a professional. They can touch up adjustments.

Else, if you want to try yourself, more in the TV repair FAQ.

When you took the back off, the screen control on the flyback got turned slightly clockwise. The set will need to be repaired because the bad connection will eventually corrupt the eeprom and then it won't power up. Chuck

Chuck has the exact answer. Iv'e probably repaired 75 to 100 of thos sets, RCA and GE, same thing. If the eeprom craps out, all settings are corrupted.

Tom1954, Do you remember what the approximate repair charges were? I'm trying to weigh repair vs replacement. Thanks.

This probably won't be much help, but 7 years ago we charged between $50.00 to $60.00 U.S. for the repair that RCA specified. They had us use a special solder that would stretch and contract with temperature swings so the connections wouldn't break again. Chuck
