I know it's been a while since you have sent this request, but if you havn't gotten any help or repaired the set by now, I'll try to help if I can. Your set has a seperate power supply board internally. The fuse could be burned out on that board. Also if you did in fact get a power surge, you may have a capacitor or a series of capacitors bad. Check the fuse first and if this is not the problem, I suggest you replace the power supply board as they are not real expensive. Good luck and I hope this has helped in some way

Had a power outage and tv was on when power came back on , heard a pop , now tv has no sound ?


If you have one of the newer flat screen TV sets; power the TV off and then unplug the set from the wall outlet for a couple of minutes and then plug the TV set back in and then power it back up. Lots of newer flat screens have a power supply system that will not reset properly after a voltage spike or a power outage that is a short duration. By unplugging from the wall outlet and letting the power supply drain all the way to a zero (0) setting it usually resets ok when you power it back up. good luck, Dennis

The power went off and wen it came back on the tv wont turn back on


If your power outage wad caused by a surge your tv may have died. Check fusebox for tripped circuit breaker also check tv wall plug fuse in case that has blown. It might be that the tv internal fuse has blown, you should disconnect the tvv from the electricity supply if you intend opening the rear of the set to check this.
If they are all okay the set probably needs the services of a trained technician

Good Luck

My hitachi tv 42hxt12u will not turn on and I have a blue light I can see


You have a light indicator suggesting the power from the wall outlet to the TV is functional. The main circuit board is not powering up due to a short circuit from a power surge or internal fuse outage.

Viore tv won't power up after power outage.


I would first test the outlet. Unplug the TV and plug in your vacuum or other loud or bright object. Turn on test object - if there is no operation, then you have a tripped circuit breaker. Find the electrical panel ( Grey box mounted into a wall, usually in a closet). Find the tripped breaker ( typically the switch will be halfway between on and off, and many have a red indicator by the switch base). Turn switch to off fully, then back to on.
Retest outlet.
If still no power to outlet, unplug everything from that outlet and call an electrician - there may be a serious problem with the wiring!
Hope this helps!!

We had a power outage today and our tv won't turn on - there is a green flashing light on the front panel and that is it.



Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

I have a Magnavox TV/DVD and i recently had a power outage. The power came back on and turned on the TV and the color of the TV screen is a purple or green tint. There is only a tiny circle about 1 inch in...


Remove the the plug from the wall socket(power) plug it back after five minutes. If the power outage was caused by lightning, then it is most likely static on the screen.

ILO 2706 TV WONT TURN ON


This TV might have been affected by the power outage even if it was not ON at that moment. There is a standby voltage still present even when OFF and connected to the AC line.
There might be different failures on this TV:
1. The power supply might be defective after the power outage.
2. The main board could also be defective since the power supplies for today's TVs are not well regulated and once the voltage getting to the power supply increases, the standby voltage voltage will also increase damaging voltage sensitive components like the microprocessor or memory circuitry.

Let me know if you require further assistance.

Tv wont turn on


Hello tvlover, The outage actually is not the problem but the spike that happened when your power came back on did the damage. That aside, you may just have a blown fuse. If you are able to and feel comfortable work with electronics, with the TV unplugged from the wall, take the back off of your TV and take a look at the line cord going into the circuit board, this will lead you to a fuse holder, look at the fuse and see if the filament inside has been blown (opened). If the fuse is blown relace it with one of the same amperage and voltage which should be written on the metal part of the fuse. Once the fuse is replaced, plug the power cord back into the wall and power it up. If it comes on and plays, that was your problem and you can turn the TV off unplug it and put the back cover back on, plug your TV back into the wall and enjoy. However if the fuse blows again, that could indicate a problem with a short somewhere in the powersupply path and that will require troubleshooting the set. Now I we have to troubleshhot this TV you will need a multimeter, an oscilloscope, and a schematic of the TV (at a minimum). If you do have electronics experience to this level and do not have this type of equipment, You will have to take the TV to a repair shop. Thank you, and I hope that it is just a blown fuse.
