I don't think this TV actually has bad caps, and I failed to find any with bulging or electrolyte expulsion on the bottom of the capacitors. The specs for one (lonesome?) capacitor are 85 deg. C, 1000 uF, 10V, and the designation T53.
I turned on this TV, got the expected behavior (blue screen, acquiring signal, transmitting image), and then after a second, a series of vertical lines about 10 pixels wide, but never a good image. LCD itself is fine.
FixYa indicated two possible problems, both of whom point to the video chip. I think this was inscribed or etched on that chip:
DCRe
SVP
EX52
7052 LF
A HDD02
D1W95.1
0532/D5082033
(c) Trident '04
I removed the old thermal epoxy, and used four sparing drops of Loctite Control Gel and Arctic Silver 5 on that heatsink. No change in behavior, even though I have yet to feed it a signal.
I'd like to reflow the solder on that chip (with a heat gun? mini blow-torch? tealight candles?). Yes, this would be my first reflow. I'm not even sure if I'm using the correct terminology, but I'd love to find an instructional URL detailing solder reflow for dummies.
I'd be grateful for your feedback.
Thanks for reading.
