Hey guys,
I have a Vizio P502ui-B1E with no display activity at all with the power light on. It broke in a very specific way, and now exhibits strange behavior when turned on (slow response to power off command, restarts every 90 sec, more below), so I'm hoping that someone with experience working on this TV can point me in the right direction.
I already tried the 2 most common fixes with no luck:
- Replacing the T-Con board.
- Re-flashing the firmware on the U202 chip (from here: https://www.badcaps.net/forum/showthread.php?p=840012)

Hello everyone! I've found this television, and I began troubleshooting it.
First, the television kept rapidly power cycling. I've warmed up the capacitors with a hairdryer, and after 3 dimmed red blinks, the backlight turned on, then turned dim, and no picture was present on the screen.
I believed that this was caused by a bad power supply producing insufficent power (I've measured 3.5v on the 5.2v rail), so I've blindly recapped the board.
After the recapping, all the voltages stableized, however, the issue in the title still remains.

Hi people!!
The owner said it showed bad picture once in a while (attached)
I see that there is back light but no picture.
I want to ask if it is possible to disable the NVIDIA GPU and use the intel one?
Also attached schematic and BDV

I have had these 70 watt high pressure sodium yard lights for many years now probably at least 15 years or more and there is a protection diode that after several years starts to go bad and when it does this it has momentarily shutting down the light and then a few minutes later it starts working again
This about the forth time I have fixed this one and you can tell if it the diode or not if it lights up and it only shuts down when the air conditioner turns on then it is the diode
If it cycling on and off constantly then it is the bulb itself that is the issue
