Re: Sceptre TV Red light won't turn on.
"I checked the output voltage coming from the power supply, and all outputs are holding steady at the output voltages." What are the Voltages and how about signals Voltages?

Hi all,
I've got a LG 50PK590 plasma TV which upon plugging in will click three times and the red LED in the corner will come on and stay on, the TV however doesn't come on (no humming, sound, video, etc.) and using the touch controls or the remote does nothing. On exceptionally odd occasions, the TV will come on and work normally when plugged in and will last about 5 minutes before going back to off and unresponsive.
I've got the back off of it and none of the caps stand out as visibly buggered, I've also tested the three resistors in the corner of the power board which...02-24-2025, 07:23 AM -
I had a desktop form factor mini-server die on me a few weeks ago. Through my initial diagnostics, I was convinced it was the motherboard because when I shorted the Green wire on the ATX connecter, the multimeter gave me all the correct voltages on the various pins of the ATX connector and 5VSTB was also correct. To my surprise the replacement motherboard wouldn't turn on with the case power button either. I threw in another PSU and it turned on right away. This is an 80 Plus EVGA 430W PSU with PN:100-W1-0430. I pulled the cover off and don't see any immediately obvious blown caps or scorch... -

Hello everyone, I am new to this PS5 troubleshooting, I need help on diagnosing the problem. My PS5 Slim board EDM-040 that beep and only shows blue light then immediately turn off.
I've checked the PSU its normal 12V. I've checked all the capacitors its all good no shorts, but there are 2 caps shorted, I think its near the SSD. You can look at the image attachment.
When tested it only shows 0.003 while other caps show 0.4 to 1. WHen in continuity mode those 2 caps goes beep/shorted.
Any help to where should I check on or suggestion would be very appreciated....02-08-2025, 11:00 PM -
My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
Then I get an idea to take it apart and clean boards from dust.
In side of Tv was not so bad, I take compressed air in can, and gently blow up.
Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher...
