Hi everyone,
Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.
Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.
I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue.... -
Originally the tv arrived with dimmed backlights (not failed leds) but everything else worked ok. Adjusting backlight in menu did nothing but voltage changed on dimming control pins,
0% p_dim at 1.65v and a_dim at 1v
50% p_dim at 3.3v and a_dim at 1.65v
100% p_dim at 3.3v and a_dim at 2.88v
Changed backlight leds anyway as always like to have complete peace of mind they wont fail shortly after selling the tv. No change as expected!
Leds are 2 rows of 15 6v leds.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Dell laptop (E7440, uses the notorious CD3301B power controller + MEC5075 EC + BQ24715 charger IC)
Symptoms:- Laptop works normally on a pre-charged battery.
- Battery does not charge when adapter is connected.
- Without battery:
- Laptop powers on from DC adapter, passes CPU/RAM init checks, then cuts DC power abruptly.(seems to shutdown one of the mosfets in the charger path). Then the loop continues indefinitely
- Speakers “pop” when power cut occurs indicating harsh sutdown.
- If RAM is removed, the system shows RAM missing blink error code indefinitely without cutting DC power
