Question about Televison & Video
A transformer blew and surged, and we lost 4 of our 7 LED TV's was wondering if these may be repaired. They do not turn on
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.

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
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.

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.
