Vizio p502ui-b1e no picture! Help please!
I went to turn on my vizio p502ui-b1e the other day and it powered on and i could hear sound (digital antenna channel), but the screen was black. I then began cycling the inputs and tried to power cycle and unplug it with absolutely no picture. After doing this, it will power on but i have been unable to get any sound now (including the start up sound). I tried the flashlight technique, but couldn't make out any image at all. When i turn it on, the power idicator light in the botton left corner lights up and then slowly fades. I found the following video and it shows exactly what my tv is doing.
I ordered the eeprom from shopjimmy and took it to the electronic department at my work and had it replaced by a coworker. I then replaced the board, but it still has the same problem.
After more research, i am leaning towards replacing the led strips and led driver.
Do any of you have any insight on this? I would like some trouble shooting tips before blindly replacing part after part lol. Any help or advice would be greatly appreciated.

I am having the same problem. I replaced my power board today with another power board and still having the problem. I notice that after power power light fades away the V logo disappear shortly after but I can the plug for the optic cable is still lit. hopefully someone has a remedy soon.

i replaced the eeprom twice n all it did was go from being a black screen to a blue screen

Baking the main board works. Not sure for how long but fixed mine

I agree with someone else who said baking the main board works i’ve been doing it for almost a year now and never fails even though no one believes me. I put it on 375° F for 10 minutes
