Guy brought this RCA over last night, say's it's his Dad's. Powers up and audio's there, but no picture, (no backlight, no vid-display). it's got 2 boards & a T-con.
HV Inverter transformers on one side.
What is it with these mystical 1/2 black 14 pin Molex connectors I keep finding? ..lolz! Unreal, this is #3 in what? ...week?, 10-12 days? Since that 60" Westinghouse.
I may have figured this one out already , 2-3, pregnant shorted 16v 1000uf lytic filter caps slowing down the show at final outputs, and a starving ground syndrome at HV inverter (once again third times a charm)
(look at those factory, big-$$$, mount ground screws for the inverter, Now how much would ya pay???...
(I'm going to replace 'em with real ones
after closer inspection, looks like be Replacing caps CS3, CS5, CS6, CS7 on PS board 40-6PL37C-PWD1XG, chance that they took out regulator(s) maybe, will check, defective caps kept my 24v & 12v off
inverter transformers seem to ring ok, going to have to dig in some bins for yet another 14-pin molex, or reasonable facsimile....
Be back with the verdict later...
