This LCD will power on and the power button stays green as normal at all times when the the panel is turned on. When turned on the diagnostics screen displays for about 1.5 seconds then it goes dark. I have swapped a known good inverter in the panel and it performs the same way. I have not seen any caps that look abnormal on any of the boards. When I shine a light on the panel after it has gone dark, but is still powered up, but I do not see any image.
I have not been able to see if all of the lamps are coming on when the diagnostic display is working. I do not have an easy way to see the lamps turn on or swap them out. That is the direction I am headed next, but I am running out of ideas and would appreciate any help on other things to try. I do not have any other boards to swap with. The know good inverter I used just happened to be the same board as used in a good 1704FP.
Any help?
Thanks.
