Ok, I got a look at the GV42LHDTV set today... my nephew got the back off just fine, wow what a pile of screws!
My observations:
PS board; no bulging or oozing caps could be seen, fuse near input checked good. I could not find any test points, but the output connector wires labeled "12V" had about 12.02 volts and the those labeled "24 V" had 24.62 Volts. Are there more points that I should check, or is the PS ok?
Main board; There are indeed two small surface mount fuses near a connector...a 3A and a 5A if I read the tiny print correctly. Both checked good (0.2 ohms or less). No bulging or oozing caps on that board either. Looks like perhaps 10 or so surface mount 3 terminal devices... are all of these regulators? Anybody have a diagram of location/output voltages of these devices?
Refined symptoms... Plug in TV, orange "logo shaped" pilot light comes on... turn on, the logo changes to white (perhaps not as bright as usual, but that
may be a perception thing because the screen is not lit). No pix/ No sound. Neither the switch nor the remote will turn it off, must unplug to get back to the orange "standby" pilot light.
Thanks in advance for any ideas, how many boxes of .22LRs should I get?
