Hi @dallascrowdis ,
Check if there is an image on the screen at all, by shining a torch at an angle close to the screen.
It will be very faint if it is there so trying in a darkened room may help
If the TV is no longer covered by the warranty, disconnect the power from the TV and remove the back cover.
Then disconnect the cable between the mainboard and the power board.
Reconnect the power to the TV and switch on.
The backlights should come on and stay on. There will be no picture because the mainboard is disconnected.
If no backlights, then you have a backlight problem.
If there are no backlights (or even if there are) do you have a DMM (digital multimeter) and know how to use it?
If so measure the voltages shown on the power board and check if they are as stated.
Be safety aware if you try this as there is exposed lethal voltage on the board that you are testing the voltages for. If you don’t know what you’re doing then don’t do it. It’s not worth it. Call an expert
