Insignia NS-50DR620NA18 TV problems

[spike3333]

Hello,

I have a Insignia NS-50DR620NA18 TV that developed vertical lines on the screen (see pic). After doing some research on-line I decided to purchase a replacement SHARP PN-UH501 T-CON BOARD 55.50T32.C13 55T32-C0F from eBay. I received the new PCB and swapped it with the old after confirming that the part numbers were identical. I turned on the TV and I now get a blinking red light near the on/off switch a black screen. I replaced the old PCB and I get the same blinking red, black screen.

I checked the voltage out of the power supply and it appears to be correct, 16 V on three pins, etc.

Any ideas as to what changed and what I should try next would be greatly appreciated. I can order a new main PCB for about $50 shipped.

Thanks,

Do you have 12v to your t-con now?

Sorry for the late reply. I wasn't notified there was a message.

Where would I take that reading. I included pics of my PCBs.
