Could be an open internal fuse or power supply failure

The most cost effective thing to do is just replace the TV. The cost to repair will be close to the cost of a new LED flat screen, they are very cheap now.

This would be the best bet. Hacking is bad and not a good example to set to keep him happy. This is an email where you can request some help. AnimalJammerItems@Gmail.com

That's really odd that a power outage did that. I would try unplugging the TV, hold the power button for 10-15 seconds and then leave it unplugged for an hour and come back and try it again, that will for sure reset everything by removing power from it. If that doesn't have any effect then its possible the mainboard got damaged by a surge.

The inverter broad is part of the power broad.

Its probably a bad T-Con board as long as the screen itself isn't physically damaged, no cracks, etc. But if the T-Con board won't fix it then its not worth fixing, its going to be hard to get a replacement LCD panel, if not expensive compared to a new TV. If the T-Con board is cheap enough it might be worth a shot to try that, and if it doesn't fix it then its time for a new TV. Sad but true on these!

Power supply fault. Repair the power supply.

Bad cable! How does TV attach to the satellite receiver? Coax, RGB, etc:? Try another cable first and foremost. If the cable is DB15 one bent pin in connector will cause exactly what you have described. Always check cables first!

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.
