I had some freak lightning strike action not too long ago. I had my computer on a surge protector, but I cannot get my computer to boot back up. I get lights and fans, but no beep or phoenix bios screen, and subsequently no boot up. Is there a way to load the bios via cd/dvd drive?
Try removing the power plug at the back of your PC then the processor and memory for 10 sec. and then put it back...power on and observe...if you got same problem try to test each caps, fuse and transistor of the board probably around the proc.and mem. area...you might point out which piece to replace.I hope that would help you..

Outdoor network cables or power cables are routed overhead.
A switch is deployed outdoors but is not properly grounded.
Damages of Lightning Strikes
If power cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn the power supplies.
If network cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn interfaces of the switch.
When a switch undergoes lightning strikes, overvoltage is induced by lightning on network cables and transmitted to interior of the chassis. The surge protection measures, such as lightning rod and chassis grounding cannot prevent the damage. Therefore, surge protectors or surge protection circuits are recommended.
Surge Protector Use Precautions
Take the following precautions to protect a switch from lightning:
Ensure that the ground cable is connected to a ground bar or a ground point on the cabinet.
Avoid routing cables overhead in an outdoor environment. Bury cables underground or route them in steel tubes.
To protect network interfaces against lightning, use 8-line surge protectors (or Huawei certified 4-line surge protectors).
When installing a network interface surge protector, connect the IN end to terminals and the OUT end to network interfaces of the switch.
If a fixed switch is installed in a network box, follow these instructions:
Connect the ground cables of the switch and surge protectors to the ground bar in the network box.
The maximum length of a ground cable cannot exceed 40 cm, and a length of smaller than 15 cm is recommended.
If the network box is located outdoors and power cables are routed aerially over a long distance (more than 300 m) to the network box, it is recommended that you install a power supply surge protector in the network box. The decoupled power cable must be at least 3 m long
Most of the time after an appliance has been hit by lightning, it is toast. In the case of a printer you can probably buy a new one for the cost of the replacement part. Next time make sure you also purchase a surge protector to plug your computer and printer into and then you will be protected from lightning strikes.
The damage from a lightning strike tends to be random. Sometimes it's minor, and only a few parts are affected. Other times, many parts are ruined, or destined to fail soon as a result of the current surge.
If the strike came over the power line, the input surge protectors in the power supply should be replaced, even if they look good. It would be prudent to replace the entire power supply. If you had the set plugged into an external surge protector, that should have taken most of the hit and should also be replaced. (Some surge protector manufacturers will pay up to a certain amount for repair or replacement of equipment plugged into their products if it is damaged by lightning.)
If the lightning came over an unprotected input cable, fixing the set would be a gamble. You could end up changing a lot of modules, beginning with the main board.
It sounds like the device may have been damaged by a power surge. If this is the case, it will not be covered by the manufacturer's warranty. If you had it attached to a surge protector that has a connected equipment warranty (and the device was still damaged), contact the manufacturer of the surge protector and tell them what has happened. They will be able to help you further.
If the router wasn't connected to a surge protector, your only option is to purchase a new router.
Is it plugged into a surge protector? When the power comes back on to a lot of residents at the same time, a power voltage spike occurs that can damage electronics. All items that have any electronic circuits, need to be protected by a surge protector. Surge protectors do not protect against lightning strikes.
Find out what the F03 error is for and then check out the appropriate area. If there was a strike of surge the most likely place to look for damage is the area where the electricity first enters into the device.
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.
Seems a lightning strike took out my bulb eventhough i have a surge protector. after replacing the bulb perhaps 1 hour later a shadow began to appear at the top of the screen and progressed slowly down until only the edges are visible. please can you help?
