Heard a pop and then the tv wouldn't power on.  so i researched it and replaced the power supply. I just turned it on to find this. I was very careful and never put pressure on the screen. Is it fixable?

It is a QN75Q60rafxza and it has gotten worse when i took the power supply back out to clean the connections. Does the power supply control the leds?

You probably bought the wrong power supply and overloaded something in the TV

Apparently the power supply and the led control circuit are on the same board. I bought my part from shopjimmy.com. It is the correct board. same part number and model of the tv. I contacted them last night and a new one is on the way. Hopefully this will resolve the issue.

i got a replacement board to verify and the new board does it as well. So do i need to replace the control board or is it the screen?
