"no disc" error on all types of media
There actually are 2 adjustable potentiometers. To find them unscrew DVD tray and flip it over. Adjust only one, first from ribbon connector. First mark somehow its original position. then start turning clockwise a hair at the time until it start playing disks again. I just fixed mine. Good luck.

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.
