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.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

After all of...

I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...

Hi all,

I'm working on my Samsung QE65Q9FN (65" Q9FN QLED, European model) with relay clicking and no picture. The power supply board in the display itself is the BN44-00944A, known on the board itself as the 65A board (silk-screened designation). There is also a second board, the 65B, which looks identical but is only partly populated for the LED power.

Symptom: Continuous relay clicking on the one connect — TV will not start up, no picture. However the standby LED is on constantly — so the standby supply rail appears to be alive and the...
