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.
