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.

Mine did the same thing. Unplug the basterd and wait about 30 minutes. Unplug all auxilleries connected to it too. Then plug it in again. The red light should come on. The problem is that the liquid crystal power supply got switched off during the outage. If that doesnt work then you have to check the motherboard section 5V. If it is off you should see a number 1. If its on you should see a number 0. Thats what the schematic drawing shows. I found this in the online manual for troubleshooting dynex flat tvs. Fortunately I didnt have to touch the motherboard. I'm not telling you to go inside the tv and get yourself killed. Think safety at all times if you must go inside. Find the manual too. I dont remember where I found it, but you should be able to find one.

What you have to do it go to the TV Menu and go to channel. Then go to channel scan and do one of those. THe problem is that is just doesnt know where to look for channels, but a quick scan will fix that.
