Toshiba 37av50u tv, won't power on. Nothing looks fried. None of the caps appear to be bulging or leaking. Solder joints all look good. Wire connections all look good. Getting continuity across the power supply fuse after removing it from the board (continuity before removing it too). What's next??

I just recently had my tv die from a power surge in a thunderstorm. My dumb ass had plugged everything else into a surge protector... Anyway, I found that my board had no continuity across like, 4 or 5 diodes. I guess I could have replaced them, but fuck, I just ordered a new board for $40 including shipping and called it a day. I recommend you do the same. My board was also a cheap POS that didn't even have a fuse. Cheap Walmart Black Friday shit.

Check the output from the power supply board. If it's fucked, replace it. If it's not, then it's the main controller board and you're out a TV.

will probably end up doing this. where'd you get it from?

>>1242293
that's the bit with the 16 multicolored wires, right? will look up how to test it and give it a go, thanks

TvPartsGuy.com Their return policy sucks but it's there to prevent people just sending back their original busted board. There's always eBay and other sites too.

I found a schematic right away googling it
No idea if the site is safe without adblock/noscript/whatever, but I didn't catch anything, and I think I've used that site before
"elektrotanya.com/toshiba_37av50u_sm.zip/download.html"
There will be a link on down, like this is free of charge etc Download

Don't bother opening any of the HTML, Full of references to the toshiba zeus engine for repair techs, not zeus virus. You don't have toshiba service manual, so you'll just have to open DWFs yourself.
Autodesk has free online viewer. You should be able to find the schematic for the power supply and start checking voltages.

brilliant, thanks man

>>1242309
still learning. wouldn't know how to make heads or tails of schematics. i know my way around a multimeter but not well, and i can solder things successfully. beyond that the pixies are a mystery. i'll take a look though, thanks for the link m8
