    Follow up post: the power light does not blink; it remains lit (solid red light) but nothing happens at all with the system - it doesn't turn on or make any sound as if it is trying to turn on. Could it be a fuse, capacitor or power cord issue since it happened after storm? LG offered no solution and I cannot find any new replacements of this product.

Have an LG26Lx1D for about 3 years, dropped off by my son.(Figures).Power light just blinking, but went back to red.Removed back panel, and metal cover. Just above antenna/cable input, its a small fan,mine was full of dirt. Blow off dirt, and make sure its turning freely.
Install back the covers, an voila....its a miracle...its working again.
Good luck

This model seems to be having a ton of power supply problems.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

SOURCE: we had a thunderstorm with

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).

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Power surges, such as those caused during lightning storms, can often cause power supplies in electronics to fail. Sometimes, if you're lucky, the manufacturer will have placed a protection fuse in the power supply which can be replaced after a surge. If there is no such fuse, the power supply typically will need to be replaced for the equipment to regain function.

It is VERY IMPORTANT to use SURGE PROTECTORS on all electronics, especially if you live in an area where thunderstorms are commonplace. This will protect your electronics from most (not all) surges that would otherwise zap them into failure.

Why wont my 42" vizio razor led hdtv turn on?


The TV's power supply has certainly got affected. Most probably some of the ground tracks might have got burnt along with a few components and this might require attention by a qualified service technician.

An electrical pulse from the thunderstorm has affected your TV. (Was it on a surge protector?)

There is a small possibility that it will come back.

Unplug the television and let it sit for an hour or more and then re-plug it.

If you need to get a new TV, also get a good surge protector such as Panamax.
