hello there,
I am trying to fix a Walker 40 TV - it has Vestel 17IPS71 3R3 as PSU and 17MB82S for logic.
How I got here...
The TV had shorted USB connector, which I fixed. TV turned on. Ran for a few hours on HDMI input. Started to see some dark dots/patterns on the screen as seen on the photo.
I restored to factory setting. The TV has rebooted only to a blinking standby LED. It sat there for a number of minutes after which I disconnected it.
Now, after plugging it back in - there is not even a standby LED.
My 17IPS71 provides 12V, no standby... -
Hello!
Bought a used TV last weekend and everything was fine when I tested it. Back home I tried to connect it with my PC via HDMI. I noticed that the picture didn't quite fit in the TV's picture and so I tried to change the output resolution on my PC and then changed the picture formats on the TV. I still didn't get the picture right and stopped to google the problem and then it happened - the TV died on me after I got to use it for 30min.

This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.
Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today.... -
Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

Hellow guys , i really need your help here.
Lately i have a problem with My TL 866 II Plus programmer, and to be more specific many times on various IC ( Winbond, Gigadevice Mx) i get Check ID Error while i am trying to read the IC. Has already been detected without any kind of problem, but the only to read them is to uncheck every time the "Check ID " option. After that i can read it erase it and re-program it only to get another error at then end saying that can not verify the programing went well so i have program failed. So i am trying to find out what is going on? I...
