Question about LG L4200A 42 in. HD-Ready LCD Television
Hi again !
After a few (6) hours of troubleshooting i finally fixed it !!
Underneath both powersupply and signalboard, there is a third circuitboard that sends the signal to the monitor it self (i guess). On that board there was a small, small fuse, it said F1 and 1,5A, 63V.
Soldered two cables and put a regular glass-fuse instead. Voila, it works !! Hope this helps for someone else.

My 42" LG did that exact same thing all it was was a 71 cent capacitior that controls the input functions. It is located on the main power supply board on the left side of the tv (with the back off looking at the back) if this is your problem you will be able to see the end of the capacitior buldging out a little bit (if you dont know for sure ASK someone) If you can't find the capacitior you need anywhere local go to jameco.com they will have anything you'll need just make sure you get the same microfarad rating. Hope this helps someone.
