Static electricity fried the button panel
static electricity can damage the chips on the boards. it all depends were the static voltage went to, if it was just to the buttons controller board or to the main av board. you could need new button board or you could need to replace the main board and the button board its hard to say with static shock.

the problem can be fixed by replacing the digital main board. if its under warrenty take it in and have it replaced for you.
Shuts off
There is a short on the video controller and when it heats up, the circuit opens and disconnects or what we call a short circuit. A technician can locate that point with his/her test equipment and do a repiair.
Won't turn on
I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves
checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.
Inverter transformers
If these are faulty or short or burnt you will need to order and replace with the original type from the manufactures.So check for leak or short if the inverter transformer is not oscillating or working.
