> Hello, Techs!
> This Tv tried to turn on for 2 seconds then shutdown, I have changed all
HV capacitors C4401, C4402,c4403; CR4118, and check all CAPS in power supply
no help. Isolated 2 audio O/P IC's TDA2052, power stay on. I order new IC's,
put them in, again TV shutdown. I do have -17V and +17V to both IC's.
Isolate B+ & B- on new IC's power stay on, pix is OK. What am I missing
here? Please help!!!!
