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.

Sorry,this can't be repair or worth repairing,because replacing the LCD screen panel or any tvs screen panels for that matter,will cost the same as a new tv.The tvs screen panels are 90% of the tv.The tv corporations produced limited screen panels,that what they charge for a tv screen panel same as a new tv,no where else u will able to find the screen panels.Ur tv now,only worth as electronic boards for parts,that it.
How to fix handshake error on lg 42l
Shake with both hands for a firmer grip :-)
Seriously, what's a handshake error?
I know what a handshake is in technical terms, but I've never seen a TV - or even a computer - specify that it had a handshake error.
42 in LG LCD TV turns off by itself
Found that TV started switching off by itself. Would try to come on..green light blinked for 2-3 seconds, tv came on (with picture and sound) for 1 or 2 seconds and then it would turn itself off. Found that the issue is with one channel only. If you are facing this issue....try quickly changing the channel the moment it comes on. You can do it either with remote or with the TV buttons directly. also in the same logic, if this is still happening, try changing the source to another (rgb-pc, av1, av2 etc). Basically change it from whatever input it is on currently, if changing the channels does not work. My symptom was that the tv made a loud 'TIK' 'TAK' sound which is louder than normal.
Why isnt my samsung tv powering on?
usually with samsung tv's they use 10 volt capacitors on a 12 volt circuit board , most definatly one of the capacitors has bulged or popped on the power board if you do not know what a bulging capacitor looks like please google a pic of it then take the back of your tv and check the power board for bad capacitors
