Re: Samsung ln46a500t1f clicks wont turn on
Measure all voltages on the connectors/test points on the power supply board.

Re: SONY kdl40s2010 no power
Replaced the diode and capacitor(looked ok, but just in case) and it's back to life. Thanks for all your help! Happy New Year everyone!Leave a comment:

Re: SONY kdl40s2010 no power
Thank you CapLeaker for your reply. The 3.3V is missing. I measured the diode/cap you suggested and they're ok, but I found a bad diode D6305 which is shorted. It's around the same coil/transformer so it makes sense. It's 10ERB20-TB3 a fast recovery 1A/200V diode, so I've odered the equivalent UF4004. As soon as it comes I'll change it and let you know the result. Hopefully the rest of the components are ok. Thank you!Leave a comment:

SONY kdl40s2010 no power
Hi guys! The tv doesn't turn on, no led is lit. I got the PSU (inverter) schematic and measured in various points. The main voltages going to other boards are all missing 18v, 10.5, 15v.. But the high voltages like 400V are present. Not sure how to progress, I need your help. Any test point I should try (schematic attached)? Thanks a lot...Last edited by trans_ponder; 12-26-2014, 05:33 AM. -
