Re: power surge

If your not a technician with tv repair experience, I would HIGHLY advise against that as theres high voltage in these sets even if they have been unplugged for awhile. Enough to kill ya. First thing though that comes to mind would be the STR##### regulator IC in the main power supply. That usually goes bad when a surge happens. But call a pro, Bro. Good Luck

After power surge panasonic hdtv projection tv model # PT-53WX42F wont come on red light flashes

Bobbie, It dose not sound like surge protector was real effective, the TV will have to come apart to diagnose what has all blown, capacitors, boards etc. Google search can help show how it is done.
Enter all your TV's info, will not power on repair.

No Picture/No Sound

This is very possibly a power surge, can you tell me how many times the light blinks, you probably have a bad power board now if you had a power surge.

TV Turns off

Mondern day television sets have to user serviceable parts inside them as they are all solid state and you will not ben able to look at a set and see something wrong. These sets you need specialized test equipment to troubleshoot relace and repair parts inside them. Your set suffered what alot of solid state electronics these days . A power surge will usually blow out the power supply section of a set and who knows what else. If your not a tech a TV set is not a place to be experimenting with anything .. best thing to do is call a tech to trouble shoot and give tyou an estimate. Now if you mailed in the Registration to the surge protector, and the tech writes down that this was all caused by a surge, then you shouldnt have any problems collecting what you laid out for a repair. The surge protector company,if the repair cost alot ,will contact the manufacturer to see how much the parts listed ncost and if these parts could go bad when a power surge to stop peeps from padding there bills. Make sure you get a complete itimized bill not just repaired power supply on a bill cause you wont get paid. Also make sure you call an authorized repair place for the manufacturer of your set. as its not 100% necassary, but much more legiter in the eyes of the power strip company. Good Luck

My samsung model- HCN4226W T.V will not turn on

You should always have all expensive electronics on a surge protector. It sounds like for this set the power regulators blown out as I know this set very well and seen it a hundred times!! its a power regulator IC that cant handle a power surge at all. and if thats your only problem, it shouldnt cost more then 175.00 to 250.00 to repair. Now with a surge though there could be other problems as well but from what you stated Im guessing alls ok except what i stated. Now Please do not attempt to repair yoursels, as these sets have alot of Hi voltage inside them even when they are unplugged.. Good Luck

NO POWER, Yes blown fuse.

Was this the 220 ohm in the power supply??? and if the 5 amp blew right away then it probably took out the bridge rectifyer with the power surge that comes alog with hurricane damage to the power lines as I used to live in florida and repaired lots of sets damaged from storms!! After you check the bridge rectifyers I would start looking to find any other shorts. First measure across the ac line with the fuse replaced but not plugedf in . If its shorted check what I mentioned before if its good after you replace the shorted parts you maybe in luck. need more assistance go to sams photo facts download a schematic and we will trouble shoot this together if you post it here so i can look at it. good luck
