Hi!
Current Symptoms: When plugged in, the backlight is off, the standby light blinks 2x5, then the screen flashes (When captured on video, the light seems to be coming from the top left corner of the screen). This cycle happens as soon as the unit is plugged in and repeats endlessly.
What I have done so far: When I first got the unit, it did the same thing but I could hear a clicking noise during the cycle. I visually inspected everything and couldn't find any issues that were clear to me. I traced the noise to the power board, so I ordered a new one. The tv standby light pattern and screen flash still remain, but the new power board does not click anymore. After spending some time reading this forum, I unplugged the cable connecting the power board to the main board, then plugged the unit in. The backlight came on and remained on, so I assumed that the issue was with the main board. After getting a new main board, the problem is still present. I didn't want to bother you all with this, but trying to fix it on my own has proved to be a stupid mistake. The attached pictures are of the current setup with a new power board and new main board.

Please let me know if i should try to take better pictures or if there is anything else I can do to make this easier. Thank you in advance for any and all help, I really appreciate it!!
