Unplug it for about an hour to let it reset itself. More likely to have main board failure which will need to be replaced.

LG 60PN6500 plasma tv power surged. has no picture and i think no sound. tv wont turn on but stand by light illuminates but then shuts off. in a cycle fashion. cant find my multi-meter to check fuses


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.

House struck by lightning and no picture in tv


I am so sorry but you should have claimed that on insurance. The amount of damage to all the solid state items in that set would mean that you are going to be replacing everything.

Can't find a fuse replacement...


We can't predict which components have been damaged due to lightning. Sometimes, a fuse only, otherwise more other components might have damaged. Anyway, if fuse should blow out, surely there will be any more reason. You should find it out first, before replacing the fuse. If not, more damage can be occur. Check for any shorted components, diodes, capacitors etc: at its main power supply regulator board. Be sure that there is no other defect occurred.

Denon receiver just struck by lightning.


Any time a unit is hit by lightning, it is usually a total loss. While the initial problem may be fixable, other components have been stressed and are likely to fail. Most shops won't work on these units because of the likelyhood of continual failures. Warranties won't be given or the repairs. In your specific case, the switching IC has been damaged and needs to be replaced as well as the surround processing section. This is best handled as an insurance claim for replacement.

Nothing works.


Remote receiver got fried by the voltage spike. If you have pull chain controls as well, you can remove the receiver and possibly be able to save the fan, but the capacitors, may have also been fried. If the capacitors are fried, then most likely the motor experienced some seriously high voltage too, which would mean I would replace the fan. I assume you have had the house's wiring inspected? If lightning struck the house and killed the fan, then it likely ALSO damaged other electrical components. If the lightning struck your power transformer and not your home directly, you may can get the power company to pay for this ceiling fan as the transformer is supposed to have a lightning arrester on it.

I have a 58'' HP Pavillion Projection screen TV. It was struck by lightning. the power cord is good. It will not turn on at all, no fans running, etc. What do you think I will have to fix?


As u have just said that it was struck by lightning the only way to get the TV back working is to replace burnt items on the moterboard .becouse lightning must have demaged some components on the power supply, if possible i would preffer a new power supply board

I am trying to connect my acer 5720z to my television. i have had it hooked up for about a year with no problems though the s-video port. just recently my apartment got struck by lighting and the svideo...


Lightning has damaged the S-video port on the TV and or the laptop. Take it to a repair shop, this is a hardware problem.
I would suggest getting a power board with a surge protection for the computer and for the TV.

Sony KV-20FV12 channel will not change


Pasted from another message I just posted-

It may be too late for this advice, but if you live in a lightning prone area, you should consider having a 'whole house surge protector' installed.
The cost should be well under $300 (a lot less if you install it) and with the included insurance (most often for $25,000) it is a good investment.

If your house was struck, I'm surprised you don't have a list of things that no longer work.
No, I don't think it is worth the cost of a repair, if you can even find someone to do it for you.

It could just be an expired TV.
