I have a GE TV model 13GP241 with a TX826TB chassis The problem I am having is when the set powers up, after 2 or 3 seconds it starts cycling on & off continiously.
I have no schematics for this set & its not really a cost effective repair if I have to spend hours trouble shooting to find the problem.
I have soldered alot of cold solder joints I spotted but that made no diference. Does any one have any ideas on what is causing this or what I should check ?
Thanks in advance, Roger
Check TP 15 transistor, P # 185197, or bad connection & diode in PWM power supply. I foget which location.

TP 15 tested ok, I will replace some diodes in power supply, & see,
Also it appears this chassis uses an all in one TV IC to control most of the functions
any Idea on a part # or sub for this IC ?, I have read that my problem is one of the symptoms when this IC goes down.
The number on the part is: ST6497B1/FBS I can not find it listed with any of my suppliers or find a cross anywhere.
Do a google search on the TX825/TX826. You will probably find the solution to your problem. It was highly discussed on this NG. It is unlikely that you have an IC problem. Even if TP15 checked O.K. you will still have to change it. It's a common fault with this chassis.
