Hi.I have panasonic LCD 32lnch Mod.Tx-32LXD7oA,the tv now has no life due to a bad lightning strike/power surge,I cannot see any burnt boards or blown fuses not even a standby light,my question is a repair possible and will it have a long and reliable life span regards Bob Sydney Australia.

Nobody can predict, what might have been happened to your TV after a lightning strike. Do you thing anybody can? Is any technician have a super-natural power to predict the faults that might have been happened due to lightning (More than 10 Million volts to start on stroke) ? Can you?
Contact the authorized service center. OK? http://electronicshelponline.blogspot.com/
Lightning-damaged electronics are a gamble to repair. Sometimes the problem is a single component, but more often multiple components are damaged, and even if you get it working, something else may die shortly thereafter. If you are lucky, only one board was damaged. My recommendation, if you have homeowner's or renter's insurance, is to put in a claim for the TV and get it replaced.
Having put forth that caveat, the blinking red LED hints that you may have enough left of the set for it to be repairable, especially given that much of a plasma set is already built to cope with high voltages. Try downloading a service manual and following the troubleshooting procedure. Here's the link (it's a Hungarian site, but there's enough English available to find things): Service manual eprom result list ElektroTanya Service manuals and repair...
The damage from a lightning strike tends to be random. Sometimes it's minor, and only a few parts are affected. Other times, many parts are ruined, or destined to fail soon as a result of the current surge.
If the strike came over the power line, the input surge protectors in the power supply should be replaced, even if they look good. It would be prudent to replace the entire power supply. If you had the set plugged into an external surge protector, that should have taken most of the hit and should also be replaced. (Some surge protector manufacturers will pay up to a certain amount for repair or replacement of equipment plugged into their products if it is damaged by lightning.)
If the lightning came over an unprotected input cable, fixing the set would be a gamble. You could end up changing a lot of modules, beginning with the main board.
Replace or have the powrer supply tested and eventually serviced. Lightning strikes affect two types of boards in televisions - the power supply by means of entering through the AC line and main boards by means of entering from the external signal sources. External antennas are worst and can totally toast the main board whereas a signal entering through HDMI cable from another device is less likely to be affected by a power surge. So naturally you start your quest with the power board , which is the usual suspect.
As of right now I do not believe we have an announced service for the power supply board of Sanyo LCD-24K50, but if you do not have any other options you can always try and send the power board for examination/repair through http://www.coppelltvrepair.com/newservice.
The first parst affected by the lightning strike are the reservoir capacitor, a big cylindrical component in the high voltage section of the tv, which normally blows up, opening the top cap, and the NTC. Please, check these components and replace the damaged ones.
Please understand, that a lightning will have trillions of volts, when it hit the earth. Do you thing any material or circuit made by a human being can withstand it? All are only mere saying. Not the truth.
Lightning can cause serious damage. You will surely want to get a professional diagnoses. What is damaged depends on where the surge came in at, and the intensity of the surge. If the surge came in through the power cable, most likely your power supply board has damage. But I have seen situations where the surge came in though an HDMI or coax connection and just take out the main board. But the moral of the story is to get a proper diagnoses, you could have several boards damaged.
Your Sony Bravia KDL-46S5100 might have been affected and damaged by the lightning strike. You cannot fix it without the help of qualified technician. It must be brought to your nearest service center.
If its after a lightning storm, it really could be anything. Your mainboard could quite possibly be shot. In fact almost anything in the TV could be damaged by a big surge. It could even be that your backlights went out from the surge too.
Does your power LED come on? What is it connected to? Directly to the power board or is it connected to the mainboard? If you have current through all the circuit boards, you may have a burnt tuner or chip on the mainboard.
Might not be worth fixing depending on the size/model. If its a big LCD, you could probably get a good deal on a working one of the same size with a broken LCD panel (~$100). Then you can just replace the broken LCD panel with yours and you have a fixed TV.
