GE TV power-on problem.

I have two GE TVs, one is 13", the other 26". They have the same problem:
After a while, them won't power up by either on-button or remote control. Unplug power cord and replug solve the problem.
It seems micro controllers in these GE TVs hang-up sometimes and need reset.
Does any one have the same problem?

Does the GE set use the TX825 chassis? If so, it could be the infamous TP 15 problem. AFAIK, it can be replaced with a general
purpose NPN transistor.

yahoo2003, Gary's right TP15 (which is your regulator transistor)is the most common one to fail in this chassis. Start there first. Voltage reads should: collector~0volts, base~7volts, emitter~3.4volts. RCA part #198752 crosses to ECG31 (leads are ECB(TP15 leads are EBC). Here are several other symptoms.

1) Power up inop. after turn off(ok at first plug in)= TP15 #198752 replacement.

2)Intermittent dead= Check by substitution of DP15, DP16 and DP21.

3)Dead/may be intermittent= Remove LP03/clean pins/ resolder winding leads/replace.

Thanks Gary and FREDDYG_001.
I know there are hundreds of brands and models of TVs, I was surprised that I could get such professional advice for an old TV in this Forum.

My 27" GE 27GT618 (Chassis CTC187BD2) power on problem is getting worse. After pushing power on button, nothing happens, then it turns itself on after 15~ 20 minutes (some times longer). Unplug it won't solve the problem. Thanks for any help.

Found a web site:

Re-soldered all ground pins around the tuner shield, it seems working now. Have to wait to see if it last.

Question 27" GE power on problem

My 27" GE 27GT618 (Chassis CTC187BD2) has power on problem and is getting worse. After pushing power on button, nothing happens, sometimes it turns itself on after 15~ 20 minutes. Unplug it won't solve the problem.
Resoldered tuner shield and did not help.
There is +5V at pin 8 of EEPROM. There is burst of 2~3 seconds of bit patterns at pin 5 and 6 of EEPROM when Pushing power-on button, but no sound and picture.
Thanks for any help to find the problem.

Unhappy sounding problem on GE TV 32GT740

My TV, GE 32GT740 sticks on silencing, no sounding. After checking, they said EEPROM need to be replaced? I want to know where is EEPROM? Do I need change whole EEPROM or some of part?

I love to learn these?

Thank you!
