Can't predict what might have happened due to lightning strike. Your set need a through checkup. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent. Search the site by type in the brand name of your set, in its search bar at the right side column, and press enter. See it in either WebView, or by desktop. MobileView has no search box.

Might be the relay on the power board that stands up just behind the big transformer. I has a complete no power also, I shorted out the relay legs on the black one, it started to work again. I will probably replace it, since the problem started by the system shutting off randomly.

Probably not, but your insurance should pay if you have a renter or homeowner policy.

Check the fuses on the power supply board first. They usually blow when you get a power surge. You may be able to replace them and get the TV running for a few dollars. If the fuses are good then the power supply board will be the issue. The main board should not be damaged because the surge has to go through the power supply board first.

Need some help with my Samsung 65" Tv

Televisions that are hit during a storm often have one, two or all the boards damaged. The voltage surge can be considerable. The problem is the diagnostics, this explains

My Samsung 65 2020 TV has developed a few color lines from top to bottom in the middle of the screen, the LCD is not cracked

Start by removing, cleaning and replacing the LVDS cable (from main to tcon board) then do the same to the flat ribbon cables going from the tcon to panel board and see if you have the same issue, if you do try a new tcon board.

Samsung UN65TU8000FXZA 2020 Smart 4K Led TV backlight stopped working, but replacing backlight strips did not work

Well, you took the right route, but sounds like the wrong television engineer. Fixing television is a gamble, but the engineer should have the test equipment and the experience to fix.

If you paid $700, you may as well pay the $150 to Shop Jimmy.

Stopped working after a storm

Did you have a power surge after a loss of power? If so your TV is ruined from the surge. In the future use a surge protector if don't already.

Repair or Junk my Samsung UN55C6500VF TV?

Hi William,
Not necessary to junk your TV. Damages due to lightning are extensive at times but from what you have mentioned it appears that may be it is only the power supply board which has gone bad and rest of the TV is ok. Replacing power board may restore your TV.
Good Luck.

No power (dead after a lightning storm hit the house. Tried replacing the two power circuit boards and have a current going in and all around all circuit boards. Still no sign of life when plugged in...

If its after a lightning storm, it really could be anything. Your mainboard could quite possibly be shot. In fact almost anything in the TV could be damaged by a big surge. It could even be that your backlights went out from the surge too.

Does your power LED come on? What is it connected to? Directly to the power board or is it connected to the mainboard? If you have current through all the circuit boards, you may have a burnt tuner or chip on the mainboard.

Might not be worth fixing depending on the size/model. If its a big LCD, you could probably get a good deal on a working one of the same size with a broken LCD panel (~$100). Then you can just replace the broken LCD panel with yours and you have a fixed TV.

My tv went dead during a lightning storm. I heard

The sound could have come from one of your power capacitors. You could tell if one of them is no longer operational by looking at them; they will be burned, or blistered, or will be bulging. If this is a CRT type of TV ensure that you only look inside if you are fully aware of how to deal with the lethal voltages that are stored on the inside of the unit.

You will need to replace the convergence chips located inside the set. Typically a repair shop will charge 150-250 to fix it. Good luck
