A modern tv is as much computer as tv and isn't electronically robust having much delicate circuitry that is vulnerable to surges, spikes or transients.
A direct lightning strike isn't necessary to cause damage and lightning activity in the area is all that is necessary. A surge protector could provide some protection but in reality disconnecting the tv from the mains and the antenna is the best protection.
In the early days of radio when circuits were more robust, an external antenna and a good ground was often necessary for good signal reception, there would be a knife switch provided to disconnect the antenna and ground it whenever there was thunder around - a worthwhile precaution that unfortunately isn't practical today.
A tv that has failed during an electrical storm might be economically repairable or might not - only the repair guy could tell you this. My limited experience with this tells me although such a tv can be fixed it never seems to achieve the same quality.

It could be the LVDS cable that is connected between the logic main board and the main board, sometimes this cable is too short and comes loose from one of the boards, it could also be a sign that the logic main is going out or the panel itself is shorting out

rither the lamp door cover switch, or the thermostat has become intermittent..neither one is very expensive but soldering skills are needed

are you sure you seen all the fuses on all of the boards, (they are numerous, and hard to spot, not like fuses you are used to looking for.) if so then your power supply is at fault and must be replaced.

Check if all the PCB board intack.Might worth repairing.

Hello; I am John at J D Electronics in Poland, Maine. I have now
repaired 9 of this same model in my shop. The set may be dead always or
work intermittently. There are 2 versions of this piece of junk, but I
have only seen this one. They all have 2 capacitors that fail on the
power supply board just above that red chopper transformer. The are
labeled C233 and C234. These are 3300 ufd at 10 volts and 105 C temp
rating. You can buy these for about $1 each from Digi-Key Electronics plus shipping. There are some cautions worth
mentioning. Make sure the set has been unplugged for a day or more
before starting the disassembling. It is VERY important to keep the set
face down on a soft surface when doing ANY work on the set. This crappy
designed set has a glass faceplate that will fall down if you don't
have it face down when all the back screws are removed and it is very
hard to put it back into position if it falls. The bottom plastic
speaker strip has a million screws to remove both from the bottom edge. Then take out all the screws for the metal back and unplug
the speakers. The connector wires to the speakers will not just pull
off without you pressing on a side release pin for each of the 4 wire-
Stupid design again!. If you are not able to solder these parts in , you can send the board to me for $25 labor plus $10 return shipping and $4 for the parts ( or send your own). We accept only cash or USA postal MO. There is NO Warranty on this repair. It is a better than 80% chance this will fix your set. Call me at 207 998 5687 Good Luck! John
