    SAMSUNG UE49MU7400U The Standy by light is on, but the TV is not responding.

    TV d3 had a software crash before, I replaced the 25Q40CLSIP IC with the 25Q32A IC and threw the software. It worked. However, after 3 4 hours, when I tried to turn the TV off with the remote and turn it on again, it did not turn on. When I press the button the light flashes but the tv does not turn on. I checked the software but there was no problem. Motherboard model BN41-2568b can you please tell me where I should look. I have the necessary devices to measure.

    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...

    Samsung UE60KS7000 No Standby Light
    by marcinq
    Hello,

    I've got a problem with a Samsung UE60KS7000 that was given to me and said that there was a problem with the One Connect box but as I understand the TV should turn on even with the One Connect box disconnected (which it doesn't). There is no stand by light.

    I've disconnected the Main Board from the PSU and when connecting to mains the backlight turns on which suggests the PSU might be ok. I've measured the voltages out of the PSU and they seem reasonable (like the labels say). The main board has no obvious burns, there are no shorts on the power rails anywhere....

    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...
