Surge outage tv not coming on


Quite possibly just blew TV fuse, but may have more damage, usually to the power supply circuit.
Unplug TV & remove back & do a visual inspection of all PCBs & wiring. your looking for physical damage, traces of arcing, parts blown apart or damaged/discolored.

HDMI ports not working. Possible lighting damage


I've seen alot of TV's with blown HDMI inputs. They seem to be easily damaged by power surges. If you are good with electronics repairs, you can locate the HDMI input chip on the main board of your TV and replace it. It is quicker and easier to locate a replacement main board on Ebay or Shopjimmy and just replace the whole board. Just make sure you buy the exact same board .

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.

It could be a fuse but most likely the power supply got damaged. You should get the power supply checked for any defective components on it that would cause cause the TV not to turn on. Most likely damage is the capicators on the power supply in the event of a power surge.

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.

Can ungrounded outlet cause damage to flatscreens?


If ever an energy pike occurs, it would most likely damage the TV for sure. A grounded outlet helps divert power surges to the ground. Sometimes grounded outlets can only handle so much overload, but never 100% guarantee.

Best protection for a flat-screen is a really good surge protector bar. The best ones cost about $100 - $150. Repairing a TV damaged from a power spike would cost about $400 - $600 from a TV repair shop. So, protecting the TV is a good idea considering the cost of repair.
