Most likely the power supply boards have been damaged. They can be repaired but I would highly recommend you take them to a shop and get them diagnosed

SOURCE: Power surge, TV will not turn on

Power surges are extremely unpredictable, they can damage everything inside the tv, from the power supply printed circuit board, to the main printed circuit board. Normally the power supply takes alot of the damage from these things, so check over the power supply for any damaged components, any burnt out parts on printed circuit board, and also check the fuse. Good luck.

SOURCE: power surge hit my surge protector with my 'sony tv hooked to it.

Well, the power supply may be still damaged by the surge, what may happen is that when first surge happens the surge protector protect your TV by sacrifing itself but then the second surge comes along, since the protector already blown up then the surge will just come right through to the TV on the second surge. That is bad problem for the surge protector that sacrify itself but can only do it for ONE time.

SOURCE: We had a storm come

Hi,
Unplug your unit for 1 hour, before you power it on, press and hold the power button for 1 minute.
If the symptoms still there, then this is an indication that the power supply board was gone to malfunction. Some voltage surge protector is not a 100% reliable because it depends how high is the voltage surge coming from the source and if the design can handle such surged to avoid damaged to the unit. In your case, obviously the surge protector doesn't react efficiently.
Yes this kind of symptoms is quite fixable but needs to send it in because I've suspected that not only the power supply board was faulty but also the mainboard because your direct TV box was also fried which is connected to the TV.
Check if your unit is under warranty/extended warranty, avail it because the manufacturer will fix it for free, but of course don't mention that the unit was fried due to storm. If not, ask for an estimate first for service fee ($300 more or less depends upon the shop) plus parts to have an idea whether to send it in or buy a new TV.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

SOURCE: I have a 47 inch sanyo. model# dp46848. A

But, was the cable/satellite feed protected? Lightning can come in from anywhere, not just the power line. The bad thing about the way cable and satellite installers ground things is, they ground to the same grounding system that the house does, which can backfeed the surge through the entire house - it shouldn't, but it can.

I would, however, contact the maker of the surge strip and attempt to file a damage claim. They all come with a liability warranty of some sort.

My panasonic tc-p50x5 will not come on after power outage. whats wrong?


Being in the field of electronics I can not stress this enough....POWER SURGE PROTECTION...and I am not talking about a power strip with "surge protection"...they are useless. That being said you had a surge that most likely blew out your main power board. There is a fuse on that board and if you are lucky that popped and it is an easy fix. If not, you will have to remove the board, get the numbers on it and search out a replacement. There are plenty of places online to get them but I use Allied Electronics. One thing to check while you have the tv apart is to check all boards for visible burn marks or damage from the surge.

Can a tv working normally after been stuck by lighting


In most cases no, depends on level of surge. I've seen cases where a surge came in through an HDMI cable and take out the HDMI port on a TV, everything else worked. I've seen cases where a surge damaged multiple boards on a set. So again it depends how how big of a surge, and whether the surge comes in through the power cable or an video/audio input.

I have a sanyo 26 " lcd hdtv and we had apower


hi you will need first to isolate where the problem might be so try to plug other unit or device in your power surge like a dvd player. if it is work your lcd tv have problem now how are you going to fix your tv, use a philip screw driver and open the back cover to gain access the internal part. since doesn't turn on check the power supply first which is the main source of supply of all the board. replace blown fuse and other defective part. bulged capacitor will not work good replace it use the panasonic brand atleast 105c ratings it is effective. thanks hope will help you to fix the problem.

Had a power surge into the house- the tv was not on a surge protector and i am wondering if the tv is blown out- or is there a fuse possibly that blows at a power surge?


hello kath... if the tv won't come on now the power surge fried internal fuse and possibly more. The least expensive way to get this repair is to physically take the tv to the repair shop. If they have to make house calls, the cost goes up significantly. Joe

The problem started from a power surge.


You may be on the wrong track here.......fly backs are a common failure,but not because of power surge. Most commonly the problem would be on the primary side of the power supply ,such as the rectifiers and sw mode regulator. If you want to prove it,just un solder the horiz out transistor(q401) and the pin of the flybackit connects to...... and if it still blows fuse ,you need to work on the power supply.......not the horiz/hv area

Panasonic 27 in TV


Power surges will attack every board in the unit, it is possible that they discovered that more boards were affected then could be changed for a reasonable cost. These tv's are not component level repair, but board level repair. There is no easy or good solution when a set has been severely damaged by a power surge. The best answer is usually to replace the tv. Also power surges are covered under most homeowners insurance.
