Earthquake - Power Surge - Picture Gone - Help!

TV has worked for a year and a half. We had a couple of earthquakes and lost power but the TV still worked no problem. Just had another earthquake and lost power and now the picture won't work. The TV is plugged into a Surge Protector. The TV still works. The green light turns on when you press the power button and you can hear the TVs power turn on. Problem is I have the TV hooked up into surround sound speakers and I powered the built in speakers all the way off so I can't check if the sound is still working or not. When the TV originally was turned on the screen would go blue then into its Auxiliary mode. Now it won't even make it to the blue screen. I tried unplugging/replugging in everything. Any help would be terrific! Thanks, Brad Guyton

WWW. Sounds like your power supply board is bad or you have a shorted board somewhere. Maxent is still in business and they are pretty good at customer service.

I bought LG 42 plasm Tv last december within 2months it broken because of the earthquake 22feb this year only screen damage can it be fix?

Sorry to read of your misfortune. The display itself is the most costly part of most sets and the price of the display plus the labor cost will come quite close to replacement cost for a new set. If the site below has parts available, they will be less cost than new:

The glass screen on the inside broke into pieces after falling from earthquake turbulance. TV still works but need to buy a new glass. How much?

First of all only a professional can do this job and call up your local Samsung service center for a price quote.It is not an ordinary glass but a special filter.

My tv has lost picture but still has sound

The 24vdc power supply section may have gone out or the back light inverter board has gone out.

VL320m will not connect with my computer via HDMI after power outage?!?!? Can anyone help me please. Tryed unplugging for 5 min that didnt work. updated Bios that didnt work. What could have happened?

Well, it could be one of a few thing, first, maybe you have simply "Lost" your Video Drivers, install your Video and HDMI drivers again, ensure you set it all up correctly, and have the PC configured for Multiple desktop, and the screen resolution and Format are correct. Also the correct External input is selected (HDMI). Now On the TV, you should also unplug the set to "Rest" anything that may have gone awry, now re-set up the TV again, after you are sure all is working, then with everything OFF, plug it all up, and in. Turn ON the TV, and select the HDMI input, Now startup the PC, it should detect the TV and you should display a picture. If you don't get a picture power off tv and try again, check all once more,if you are still no go then I suspect the the TMDS transmitter has had an overcurrent situation,often caused by a power outage and or spike, surge, if left plugged in when power was reconnected. In this case, you will need to get it repaired, or get a service manual, and maybe have a go yourself, hopefully it will not come to that.

All of a sudden none of the buttons work, we can't change any channels and it will only turn on. The TV is less than a year old, is plugged into a power strip (so there won't be a power surge), and was...

Not all power strips prevent power surge, only those that specify on their packaging or imprinted on them, that they are "surge protectors". Also, even these will have lost their surge protection once they have been hit either by lightning or a strong power surge. You would have to check with the manufacturer on how much of a hit they can withstand. Was there a thunderstorm in your area recently? Are you using a remote to try to change the channels? If so, try the buttons on the tv itself. Also try unplugging, waiting 15 or more seconds, plug it back in, directly to the wall socket. See if that resets it. If you still can't get it to change channels call the manufacturer of the tv, it may be a known problem and they may be able to help.

My Sony 52" LCD kdlw3000 tv, which is almost 2 years old, went to standby mode after our power had been off for two days due to a storm. TV worked fine before we lost power and it's plugged into a surge...

Just as our modern sets can remember user settings when the AC goes off, they well may record error conditions for an extended length of time too just as our cars do. Flash memory (used in such applications and only type used in digital cameras for example) can keep information for a very long time. Even if not used in your set, there is surely backup provisions that can keep info handy for days and possibly weeks by using components that mimic batteries to retain even standard memory for weeks.
Most PCs have provisions for discharging this kind of circuit which then resets possible stored error conditions and returns stored values to factory conditions.
Feel lucky this time I'd say.

No picture on Samsung LCD 40" TV

Nobody could guess that! it depends on where you are in the world. For Instance I am in australia network.
Call outs generally run to $AUD90 and $90 and hour Min 1 hour.
You do not say whethyer the power light lights up so its again guesswork.
If the power light IS lit then there is power from the wall to the primary coil of the power transformer. I would then suspect either the secondary transformer has failed, or that a fuse after the secondary and pre picture/sound module has blown. The power supply ( cant by bits) costs around $200. The fuse 0.60
add to the callout fees and you get some idea of the cost can cost half the value if a $1000 TV The plasma screen hasnt gone so that's always a plus and its rare for the video board and sound module to fail simultaneously. So my bet is the poer supply side and fuse

Dear Support, This is about a 42'' Sanyo plasma HDTV model no: DP42746. It's my mom's, and at ''84'' it's her window to the world. So it needs to get fixed, please help! It was working fine, then all...

Hi Ed,

The only thing you can try is leaving the TV unplugged for an hour so the TV can discharge and reset itself.

If this doesn't work, then we're talking about maybe a power supply board problem for the screen itself. Most manufactures call it a Blacklight Inverter Board. I would use the warranty for the TV if there is any. The TV repair shop maybe expensive for this type of repair. So, get a price quote first. That way you can decide if is easier and cheaper to buy a new TV for her.

Same problem here too. Happens everyday now until power is off for a while then picture is stable. Thought it was interference, but I'll look into the overheating issue a bit more closely.

First thing I'd check is the powerbar. Did you plug the TV into the outlet direct? What caused the breaker to trip? If it was an overload by using too much current, there is a possibility that there is a loose connection in your house wiring causing arcing and the interiference lines you're seeing on the display. You may even want to try the set in a different outlet if the powerbar checks ok, and if the set then works fine, get an electrican ASAP!
