Damage due to lightning would not be limited to power board only, in my opinion, other circuit board would have also been damaged so new home theater system would be good choice rather repairing this one.
Thanks.

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.

Toshiba 40FT1U TV won't turn on. Lightning pulse


Fault to the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Can't determine the condition of the power supply board, by just examining the fuse; you know. Contact any service technician.

Vizio M420nv LCD TV Black Screen


lightning can do extensive damage to electronics equipment especially flat panel TV's. I would really recommend a professional diagnosis instead of board swapping. You could have several boards that are damaged!

Power surge caused by lightning strike, TV is dead, any Thoughtd/ does this damage every components?


Lightning can cause serious damage. You will surely want to get a professional diagnoses. What is damaged depends on where the surge came in at, and the intensity of the surge. If the surge came in through the power cable, most likely your power supply board has damage. But I have seen situations where the surge came in though an HDMI or coax connection and just take out the main board. But the moral of the story is to get a proper diagnoses, you could have several boards damaged.

Emerson TV Model #LC401EM2F Fix after lightning?


Lightning damage on LCD TV's can be a doozie. You really need to get it checked out by a qualified technician. I've repaired several TV's hit by lightning, most of the time the damage was limited to the power supply board. However, it is possible that multiple boards were damaged. If multiple boards were damaged, it's not worth repairing the set.

My desktop board is P5NSLI, suddenly when i'm working with it, a lightning splash because its raining, i turned off my computer 'cause i'm worried if what may happened, after the rain i get back to work...


This may have been due to power surge. Try replacing the power supply. Also, inspect the motherboard and other components for any physical damage. Motherboard may get damaged due to power fluctuations, which requires replacement.

Sanyo dp32648 possible lighting strike, whats needed to fix and a possible cost an can i repair myself?


It wont turn on? Well if it is damaged by lightning the only thing damaged would be the varactors on the power supply. They are there to absorb tremendous surge of electricity. The same way a surge protector works. A worse case scenario is the power supply board is fried up. Then being a non electronic technician you can purchase the whole board or order on line and install them yourself. If you brought it to a shop they will charged you for the labor and the board. Don't buy used boards on the internet because a lot of them are no good in my own experience. Get a new one for about a little over a hundred buck or so.
