My tv went dead during a lightning storm. I heard

HAVE YOU CHECKED PLUG AND INTERNAL FUSES

I would recommend getting a surge protector and using that to protect your televisions. This usually will stop something the lightning from killing your tv's.. I have a surge protector and can still use my tv, computer, anything I have plugged in during a storm.

Change the input to some other you are sure works. Then if the problem persists, this might need attention by a qualified service technician.

The power supply regulator section should be troubleshooted. The "Pop" sound you heard might be of a bursted electrolytic capacitor in the AC mains rectifier section inside the TV. All the related commponets, rectifier diodes, protection zener diodes etc:- should be checked before switch ON the TV further.

The defect is likely a sensitive component to over voltage (lightning) on the main power supply. But you should not exclude other boards too, since ohter board also have local power supplies and sensitive CMOS integrated circuits. Check all MOSFET transistors on the the main power supply, since they are the most sensitives. Also the regulator IC to control the PWM sent to the MOSFET is made of CMOS (sensitive). Then check all the diodes even if they are more robust to lightning. There is a MOV that absorb the lightning that could be shorted but in your case it seems to have survived.

A lightning storm will destroy a TV in many cases. I have repaired very few, with this problem. I would certainly find a new TV, if this is the case for sure. Thanks for asking!

Sounds like it could be a problem with high voltage stages. Definitely a job for a TV technician as it is dangerous try to repair it yourself.

yes, take the back off, and follow the power cord. You will see a fuse in the board.You have the same problem as I have. I replaced my fuse, and plugged it back in, It made a sizzling sound and blew the fuse again.Maybe you will have better luck, with your set good luck rob

Defective HV transformer. (Likely lost it during the storm)...accordianman

Yes, it's quite possible that you indeed may have sufferd from a Power Spike, induced by lightning during the storm, esspecially if plugged in during said storm. I have had quite a few customers ova the years with this exact problem. I always advise my clients to unplug ALL devices during a storm, and for ones that simply cannot be unplugged then some sort of Spike/Surge Protection device MUST be used. As a matter of interest, I have written many a report to insurance companies to support a claim for a replacement.
