Pc struck by lightening. it was on a surge protector and plugged straight into the cable internet service, another pc in the house was on a SP but used a router/adapter for internet serv...it survived but the one plugged straight in didn't. What would it have fried on the one that will not turn on. which is a Gateway GT5692 almost brand new computer with 4 GB of memory and 64 bit pc. Very nice pc and I really need to fix it.

Replace the TV as it has been damaged by a power surge and the faults will be recurring.
A home surge protector will do nothing to break the power of lightning.

Is your TV plugged into a surge protector? If not it very well may have gotten a power surge during the lightening storm that fried components in the TV.
Or is the TV connected to a cable box? It could be that the cable box took the hit if it's not plugged into a surge protector.
Or a possibility of both.

mite came through your cable line ,or phone line to the tv.

Get a surge protector for your most loved systems, that way the worst case scenario is you will need a cord replacement. Unplugging it when it's not in use may also cool it down.

your tv is shot ,im sorry to say that but its burnt

physically remove the power cable for about 10 mins then reconnect it no joke this is important

if it does not work the power supply is needing replaced

do you have cable or sky

OK if you dont want to pay for this, claim it as FUSION on your home insurance policy. Any legitimate service person can repair this.

But fill out an insurance form and get 3 quotes first.

Lightening may have caused a surge on your power lines to the house and to the outlet the TV was on.
Do other things work on that outlet? If not you tripped a power breaker.If they do work check this.
Unplug the TV for 2 min or more and plug back in.
Try bypassing your surge protector you had it plugged into. It could have died when the lightening struck.
(no surge protector?) Bet you'll buy one for your next TV.
Look for 3000 joules and up rating for a surge protector and insure it has protection for a cable/antenna input too.
If this doesn't work the TV may be fried or internal fuse blown.
Time to take it to a repair shop or depending on it's age (5 years+) it may be time to buy a new TV and surge protector.
Near Lightening strikes can effect appliances from several inputs that could be affected from outside like Power, Cable, Antennas, Phone Lines that come into your house.

Your TV got fried when the lightning struck. Time to get another one.

This time be sure you plug it into a surge protector power bar, available at radio shack, walmart, any TV or computer store.

Check the power source to the computer (both ends of the cord), if a surge protector is in line with the power , remove it and plug the computer straight into the wall. also check the wall plug with a lamp or something to ensure power there. make sure the switch on the power supply hasnt been changed to the 220v side.
If no power at the wall- check your breaker box in the house
If it works plugged straight into the wall- check the surge protector
If power at the wall and plugged straight into the computer (no surge protector) and nothing lights up when you turn it on- have your power supply checked.
