Hello,
I have an RCA L40FHD41YX9 that isn't working. I tore it open and two caps were physically buldging on the PSU. I replaced them and a good cap with some Panasonic FR series caps. I thought maybe that'd fix it. I hook up a video signal and I get nothing. It's like the backlighting isn't kicking on. I see a wire going to the inverter board that has a bunch of pins. A good amount of them in a row are labeled 24v, the other ones are labeled (in a row) gnd. The 24v's all seem to check out and measure around 24v. I pulled the cover off the inverter and checked the four caps. They seem okay.
Does anyone have any suggestions on what I should check? I can post nicer pictures. I was just hoping someone might be familiar with this system and just be like oh, you should check the blah pins and see if you get blah voltage, if not, check the blah and see if it's broke!
Thanks!
