Welcome. I am Mike, an experienced field technician. We are now connected together on this convenient website where I am able to help you.

One quick thing to try is uplugging the tv power cord for 3 mintues. But 95% of the time this is failed back lights inside the tv display panel (screen). This type of repair is not done by any repair shops because it is so much labor and high risk of damaging the internal screen. However if you are really really good with tools, I may be able to direct you to some DIY videos and the parts. Otherwise this tv is not fixable.

Fine. Should I be removing the back of the TV and looking for smoke, burned fust, mouse next, etc?
Expert:  Mike G. replied 6 months ago.

There will not be any visual signs of failure.

It aint me.

I watched the video on LED replacement. However, nothing we discussed points to that as a solution. Where is the likely area for loss of the entire display? Knowing the function of the individual pc boards might point to likely sources of this failure. I'm not up on that but had hoped for some direction. More than likely a connection or one of the pc boards konked out.
Expert:  Mike G. replied 6 months ago.

This is NOT a failed board in the tv or a loose connection.

One or more of the LED strips inside the panel has FAILED and it must be replaced.

Repair shops do not perform this operation, so your only hope is to DIY.

That means taking the whole back off the tv, removing all the boards, then prying apart the display panel to access/replace the LED strips.

Hello, just checking back in to see if you still need help, or perhaps you would like to acknowledge that my time and input has been helpful?
