Power doesn't have to be knocked out for a cable box to destroy the HDMI ports on a TV. Thunder miles away will put voltage spikes on the cable system which in turn trashes the main board in the TV. You can get parts for your TV here: TV Parts Universal TV Stands DLP Chips ShopJimmy

If it says "searching for satellite" the problem is in your satellite receiver, not the TV. The TV is working. Its showing you the signal coming from the sat box. The sat box is the tuner and is responsible for the sat signal. The "searching for satellite" is a common problem after lightening issues. If you have multiple sat boxes, then swap this one with another that you know works. If this is your only box, call your provider as it means the dish LNB or the sat box was damaged by the lightening. Also have the wiring checked for bad grounds due to an improper install.

Please check the electrolytic capacitors on both of the back lights inverter board, if any of them has over heated bulging & leaking, replace them. we will replace them all.

I will check out the back lights inverter board first if there is any defective electrolytic capacitors or not, if not, the problem is the main board.

Please try to turn off the closed caption function by access the TV set up manual

I think unless it has a power converter...the straight plug should work...think about it...they didnt have to pay to get rid of it.

Defective LED back lights strips, or damaged EEPROM on main board. I will try a main board first, if you do nor have a TV LED strip tester.

The screen is ok Your T-Con board quit. You can get a new one from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Is there any sort of reset button on set?

Sadly, only testing of each component can suggest the extent of damage. Many years ago, lighting can in through the window of my living room, hit the TV, blew the knobs off the TV (that date's me), shot into the kitchen and shattered the kitchen counter top. What I want you to take from that is that the course of a power surge is a bit unpredictable. No one can guess how far it got until you find a lamp that works.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

hello dear , this problem is due to a high voltage fault from the electricity . I have read your message , before you go with your TV to the tech support just loose the TV from behind and check if all cables inside the main board are connected in there positions , second step try to loose the main board and clean it well with alcohol liquid then wait till it dries well .after that , reconnect all cables in there positions and try to turn it on , if it gives you the same fault , that means you should replace a new main board

There are no analog channels anymore.
