Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, proposed preliminary tries (if have not been done):

  • • check/re-solder the power components of the new power supply board particularly the transformers, diodes and capacitors;
  • • check the LED array.

I followed your suggestion I inspected all the solder joints under a magnifying lamp then re soldered them even thou there where no cold or bad solder joints and the same with the LED array same results. I have solder certification and inspection from the Air Force as a civilian in avionics.

Appreciate the update on the preliminary tries.

What is the voltage supplied to the LED array? Is it consistent?

Is the $18 on top of the $28?

I understand. Would appreciate an update when conveniently able on your end.

Soldered board voiding warranty $58 dollars for power board, mother board, and led board, just answer charged me $28. You suggest calling you that is $18 =$114 and more of my time. I can buy a new TV $148.
I'll trash this thing and buy a new one. Instead of feeding you more cash and then having to buy a new one.
No, I think I'll call it quits while I still can. Just answer took the $28 out already get them to credit and rate you!

I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
