It looks like the common AS15-F gamma chip failure. There are many threads on here if you do a search. Can you take a picture of the t-con ?

Yep, AS15 Gamma Voltage ref IC.
You can check the DC Voltages at VGMA1 ~ the highest VGMA (looks to #19) and report each reading.

It is bad, either try to replace the IC or replace the board.
