What's the likelihood of my TV being able to be fixed after a lightning strike killed all electronics on one wall?


Probable power supply fault now. Maybe if you replaced the power board it might work again.

Did you have a power surge after a loss of power? If so your TV is ruined from the surge. In the future use a surge protector if don't already.

My dynex tv wont turn on! the strom knocked out our power, now the power is back on the tv wont turn on from remote or tv power button.


Lightning is a weird beast, and can do strange things to a TV. Sounds like the set took a hit. If there is a fuse then check it on a volt-ohm meter for continuity while it is out of the circuit, and if it is an open circuit, replace it. If there is a circuit breaker, then reset it. If these don't work, look for obvious scorching on the circuit board (assuming you know how to avoid electricution, otherwise do not touch). Lightening can literally jump around on a circuit board, so there is no way to know what part of the set was effected by the strike - the lightening will not always burn out the first circuit it touches, but will burn out something further into the circuit. The most obvious place to look is around the transformer and rectifier circuits. If a capacitor was hit, it may be swolen or discolored; resistors will scorch, and the worst thing is that transistors and IC's often show no damage - in fact, any part might be burned out and not show visible signs. If nothing is obvious (like scorch marks) and the fusing is intact, there are too many possibilities to begin listing them all. The fact that it won't turn on at all sounds like it is probably a power circuit, but, not necessarily. FYI turning a set off during a lightning storm does not protect it, you have to unplug the AC power cord and the line that feeds the signal into the set. Even circuit protection devices (lightning arrestors) may not protect against a close strike. Maybe the techs at Best Buy can supply more suggestions (Dynex is their brand).

We had a thunderstorm with lightening in the area. The LG was plugged in at the time, but NOT turned on. after the storm, the tv will not turn on. the little green button turns from red to green...


As an electrician, when someone loses more than 1 item of electronics in a day, its almost
always traceable to a nearby lightning strike, accompanied by inadequate surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360. Surge protection can
be provided by the consumer at the power strip (a good one with builtin protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house protection, or per-circuit protection at
the breaker box, where a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed), other than renters insurance or homeowners insurance.
The converter box may be replaced by DirecTV, you'd have to contact their customer
service at http://www.directv.com/DTVAPP/content/customerservice
If desperate, you could try replacing the entire TV power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

Emerson tv lost the ability to power on after a storm


I would probably look at the internal fuse that protects the power supply inside the tv. The storm probably sent a power surge through your outlet, your breaker may not always work correctly, especially if the breaker is old. The fuse should be inline with the hot side of the AC power to the power supply circuit. You would have to open up the tv, but you would be able to spot the fuse very easily. Fuses are cheap, but getting to it may be a problem

Compac presario 2200


There is a high probability that your laptop has been fried, especially if it was plugged into the mains at the time of the lightning strike.
A lightning strike could damage many components and even if you could get it fixed (most likely require a motherboard replacement) there are no guarentees that some other component won't fail in the future.
If it was me, I would put my money towards a new laptop and get a surge/lightning protection power board and disconnect the laptop from the main during a lightning storm.
