I have a Samsung 55 in LCD tv that keeps powering on & off. I checked the caps & they look good and have the higher voltage rating of 25 volts not 12 volts. Any idea what the issue could be?

My tv has audio but no image. Upon opening I have noticed there's a capacitor (d153) on the power board which is surrounded in brown residue (appears to be blown). There are also 3 empty connectors on various boards, P1, P101 and P806 are all empty. P806 appears to be a test point, but P1 and P101 look like they should be connected to something. The tv turns on and stays on everytime so I'm not entirely sure there's something wrong with the power board, but the (blown?) capacitor is worrying.

Hello! I'm having the infamous black screen issue with my Viewsonic N3252W. I initially replaced the Power supply, because that looked like it was "the fix" for this particular issue.

I have a WS-65611 that I have replaced the caps on the DM board. Before I did that, the power LED flashed non stop, Now it does the normal 70 seconds but when I attempt to turn it on, it shuts right back off. After attempting a power up I checked the error code I got a short protect error. I then removed the DM again and verified the caps were not shorted to the shield and checked the pico fuse and found everything to be good. Any ideas of where I should start looking??
