power board failed check the main board the 5 volt side may have a few capacitors blown. check all of them as usually when 1 starts to go rest can follow don't cost much to replace. the ones next to the heat sink are first to start to wear out, use the ratings that are on the old capacitors and replace the same 105c temp rating. and rating to failed capacitors, you will see the faulty capacitors they will have blown bowed tops or a liquid on the bottom of them

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. 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 power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Try a hard reset. If it do not help you, its main board is faulty, and should be replaced. There are two types of reset to 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; will be 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; check the site linked here.

NO... check and see if all 4 bolts on bottom of stand are tight. IF it is tilted and tight, remove the stand from the internal slide, re install. Sometimes it gets lodged behind the proper mounting point.
