Lightning Strike, Can it be repaired
I have a 2005 Insignia model IS-TV040922 that was taken out by lightning a while back ( I know I should have had surge protection for it). I decided today to take the cover off and see if there was a simple fix, like a fuse that could be replaced. When I took it apart I discovered that there was a fuse that was blown. I replaced it, crossed my fingers and plugged it in. Almost instantly the fuse blew, but before it did I noticed a spark from the doohickey, (for lack of knowing what it's called) in the photos.

My question is, would it be worth my time to locate a new doohickey and solder it in place, or is that just going to be one in a long line of components that were ruined by the lightning strike. Any help would be greatly appreciated.

It looks like a moss fet/thermistor. Take it out and take it to a tv repair place and have them match it up.

Google is your friend:

MF72 Power NTC Thermistor
Quote:

Once the circuit is energized the resistance of the MF72 will decrease rapidly to a very low value, power consumption can be ignored and there will be no effect on normal operating current. Using the MF72 Power NTC Thermistor is a most cost-effective way to curb surge current and protect sensitive electronics from damage.
