Question about Samsung LN Televison & Video

Samsung TV won't turn on after lightening storm. Surge protector "sparked once, but all the other things plugged in are operating.

Have tried resetting (pulling plug, depressing power switch, different power source), but still no red light. Screen fluctuates between black and dark gray if plugged in.

Contact your insurance company and make a claim. Lightning damage to electronics like that is hard to repair.

This set has a power supply and signal PCB. Since the indicator light is blinking, I would consider the problem to be a missing voltage from the power supply. Unplugging the set for a couple minutes may solve the problem. If not the set may still be under warranty. Contact LG (800) 243-0000 for a servicer in your area. Hope this helps.

SOURCE: screen went black/won't power on

This is a common problem

The first step is to check the fuse on the power supply board. Next, disconnect the inverter board to eliminate the possibility of it shorting down the main and or power boards. Be careful as the inverter board supplies high voltage to the cold cathode tubes (backlights) and it bites HARD. If you disconnect the inverter and the power led comes up then replace the inverter board. (The screen will appear blank because you have no backlighting). If the power indicator still fails to light you need to suspect the main board first before the powwer supply board. The main board tells the power supply board to come on. You need to check the trigger from the main board to the relays on the power supply board. Also check the power connector to the main board because you should see +12V and/or +5V on at least some of the pins. If no power on the relay triggers then replace logic board. Then replace Power supply board last. Or buy a new monitor!!

SOURCE: No power on Samsung TV after storm

Hello Zkarim,

I'm very sorry to hear about your unfortunate new's. I had the same problem in my own home maybe a week ago.

Basically if your power flickered on and off at anytime during this storm then there was a power surge that probably fried your TV.
* First check the power where the tv was plugged in. Is it a power strip or a surge protector ? Surge protectors typically have an on/off switch and a separate reset push button.

If it is a power strip then the tv fried because there was nothing to stop it from happening (not even the fuse). If it was plugged into a surge protector then it could be quiet a few years old and not as reliable or the surge was to powerful for the limit on the surge protector.

The only thing you can do personally is send it in for repair if it's under warranty, if it is not then you can have it looked at by an authorized repair technician in your area. Troubleshooting should be fairly low, and you will at least be able to find out your options once they find the defected part.

Thank you for choosing Fixya!

After a lightening storm, my power surge strip got hit and damaged everything that was attached to it (i.e. the internet modem, blu-ray player, and Samsung TV). Our TV only has a blue screen. Help

Yep, power spikes kill. Power spikes kill all. Power spikes kill all forever. Replace all and get a new surge protector that costs at least $99. If you never need it it is called insurance. I am in FL the capitol of lightning. High priced surge protectors are cheeeeep when lightning is there.

My HDTV went out in a lightening storm. What could it be?

Is your TV plugged into a surge protector? If not it very well may have gotten a power surge during the lightening storm that fried components in the TV.
Or is the TV connected to a cable box? It could be that the cable box took the hit if it's not plugged into a surge protector.
Or a possibility of both.

Lightening caused surge protector to "spark" but no power loss, and everything plugged in works except the Samsung HDTV

Hi, In a lighting storm you are supposed to unplug your TV. In this case you may have fried something on main board. Take it to repairman. Good luck.

How can we tell if our tv was hit by lightening,nothing else in the house was damaged but after a storm our tv stopped working??

You may have blown the fuse. From now on, please keep all electronics on a power surge protector.

We had lighnting storm pass by and our TV was plugged into a surge protector along with many other devices. When the storm passed the TV will not turn on anymore.

Likely, the surge protector failed.

Depending on the manufacturer, you may have some sort of warranty available. That is, the manufacturer of the surge protector may reimburse you for the cost of TV repairs.
But foremost, try plugging the TV directly into the wall. It could be that the socket or surge protector were fried, but your TV is ok.

We had a near lightning strike and now my tv (sanyo model ht27744)doesn't want to come on.

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.
