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.

How do i use it
Hello,
To hook up your television to your PC, first you need to get the appropriate cable which is the cable you use in connecting your CPU to your monitor, then turn the back of the television and try to connect it to the port that is on the television.
Then turn on the television, and go to the AV mode, select from the different AV channels you have to be able to access the laptop.
That is how to hook up your television to your PC.
Take care

No power at all..help
The first place to look will be the power supply section, it must have at least the 5v standby power supply working, this 5v is always ON, it is used by the main controller board to turn on the rest of the TV.
Look for bad fuse, bad/burnt connection, bad capacitors.
