This model also goes to shutdown when the run control at SMP, (the one
under the black plastic cover), is bad, replace it and adjust to 142-143
volts running. This week I fixwed one with that problem, Also on this tv
when on, dim raster with no video or sound, found open coil off pin 7
of the fly txmer, no -12V source.

I've seen this, CR4119 is just a little Leakey under load in 17 volt
source. Rick

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!!!!
TIA!
