no VGA signal after lightning strike

Hewlett-packard / Hp mini 311-1000

Specs: vista, 1.6 GHz / 1789 MB
I had lightning hit a tree about 100 ft from the house. everything ( 1 Xbox360, 1 sony 53" TV 1 sony laptop hard wired to modem and a compaq PC) connected to cable got fried. Insurance covered it all, but the deductable made sure I could only get my kid a new xbox and the house a TV. the sony laptop I tossed but the PC powers up, the fans spin , no signs of burn inside yet the monitor tells me "No VGA Signal - monitor will power off " the monitor was not involved in the hit and works ( it's actually a 21" flatscreen TV.

any ideas?

Anything showing up on the monitor (flatscreen) when you power it up?

Possibly could have only taken out the card/onboard chip. If it's a card, you can replace it. If an onboard chip, it may be much more difficult to disable it and add a card. Also, check and make sure all interconnecting cables are OK as well.

I think you ought to get a highly trained electrician there to double check the home wiring. They have a special tool that can test the insulation of all your wires. I'd be concerned that some hidden damage is lurking. This has nothing to do with the monitor.

Anything in the house could have been affected. Even if not plugged in. You have to use some known device. If you have tested monitor and it is OK then might think the video display adapter is bad but you'd have to do some other tests. Some people prove or try to prove motherboard by removing memory and see if the beep code matches.

if you can test the monitor with any other input device, please do. if the same problem appears with other input devices the monitor is probably damaged.
if the problem does not happen with other devices, then most likely the graphics card (physical card on motherboard) or graphics processor (integrated graphics part of motherboard) is fried...
if it's a physical graphics card with most computers it's replaceable unless it's really old.
if it's integrated graphics perhaps think about buying a new computer. Compaq/HP is a lousy brand.

this was entirely preventable with just a $15 surge suppressor. most have a 10,000$ warranty- if it fails and equipment is damaged, you're covered up to 15 grand. better than having the insurance pick up the tab or lose valuable data/electronics. I hope you learned something from this.
Make sure the suppressor is rated to stop lighting strikes and covers damage in case it failed from a lightening strike. I have surge suppressors on everything electronic- I've never had a lighting bolt hit close by but you never know...
