pretty low use vision pro ( multisync) 19 inch. works for 2 seconds, then black. when its black, if you shine a light on it you can still see an image. backlighting bad. note, for the 2 seconds it displays an image, its not as bright as i think it ought to be, but hard to say for 2 seconds. i installed it new in a home use game a few years ago. one issue is 2 years ago i bought a vision pro to replace a vision pro in another game. easy swap? no. the new ones mounting holes were different, and i had to become an on site engineer to mount it in the same position as the old one. it sucked. that why i want to fix this one. anyone every fix one? internal power supply? inverter board? backlight pulling down the inverter board? thanks

I'm guessing that's an LED backlight? I think that would suggest one of the LEDs is shorted and the power supply for that section just shuts down. that's one frontier I was never really successful at replacing those.
 
i did a little test, using one led at a time. i then flipped the board to try the leds in the opposite sockets. it looks like the inverter board is bad on one side. i ordered a new one from happ, 55 bucks but they dry humped me on the shipping. ground , 26.00. WTF?
