Sharp LC-C3242U Repair Thread

[PotShotScott]

So I picked up a Sharp LC-C3242U that is DOA. Pulled the cover off. Found a Delta DPS-178AP A power board running the show. No standby voltages on the DC side of the board. TV does not power on.

Did some searching here on the forums to find that D7907 is the diode that typically fails. Sure enough - pulled my D7907 out and it flows both ways. Will likely find the diode here at my local electronic supplier on Monday. Posting PSU pic of location and diode information for further reference.\

Project update. D7907 was indeed bad. Got my new diodes today. Got the TV back up and running to discover that I had purchased a TV with a cracked LCD panel. At least I only paid $10.00 for this one. PSU and Inverter board going up on eBay to see if I can make a little of my money back.

Well good repair experience. I post free pick up of tv on craigslist and don't pay for them.
