    Thermal expansion due to heating and cooling can over a long period of time causes hairline cracks in the soldered joint resulting in an intermittent connection or even a burn up which is what you have , all you need to do is re solder the transformers pins with some fresh solder to prevent this happening again.

            I have a problem with these symptoms: Seiki SE39UY04 Red standby light, not powering on

            I will start a new thread because I think that's what I'm supposed to do. But first I have to post my first post as a new member. That's what this is.

              Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
              by serious_electron
              Hello Everyone!

              I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.

              LED TV Samsung The Frame 55 inch QE55LS03RAU Standby Light only
              by ChristianBr01
              Hello everyone,
              I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
              The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
              What I already found is that the 12.8V are not an the connector to the main board connector to the power...

              This problem description is a lot like https://www.badcaps.net/forum/showth...633#post898633

              My Seiki SE39UY04 TV stopped working. I've used it for almost four years as a computer monitor.

              Symptom: the status LED is solid red. I think that this means "standby". Pressing "power" on the remote and on the TV doesn't appear to change anything. Normally it would turn blue.

              Inside, the only odd thing that l've noticed is a spot on the power supply board looks toasted. This is where one wire from the transformer joins the board....

              LG 55EG910V - no power and no standby light
              by AleMonti
              Hi everyone,
              I'm trying to troubleshoot and repair this old LG OLED curved TV, model 55EG910V.
              I did some basic troubleshooting and reviewed most related posts here, but I wasn't able to isolate the issue.

              The TV shut itself off during playback and never came back to life - the standby light remains off. My dad claims that it has happened a few times in the past but the issue resolved itself after some time. Not this one.

              After checking the basics I did the following:
              • I measured all voltages and as expected the only active supply is the 3.5V standby. It

              Samsung QLED QE65Q7FNAT only standby light
              by Kaar3l
              TV: Samsung QLED QE65Q7FNAT
              PSU: BN4400940A
              MB: BN94-12832K

              I got the tv in spring 2024. At that time it started, then ran 60 sec and poweroff. Seemed like reboot issue. I didn't have time and room to check it in summer so I plugged it in and now the standby light is on. I press button on remote, standby light goes off and tries to start?. No picture or backlight on LCD. I thought about removing diodes like in this thread: https://www.badcaps.net/forum/troubl...sung-qled-q60r...
