    Lg-42pc3d-ue

    ....hi all....first time poster here but have been reading for quite a bit.....i was given a no working lg 42pc3d plasma tv made in 06....the problem is is that as soon as i power it on it trys to start...the red stand by light turns green then makes a click a few seconds later and shuts down again to stand by...i pulled the back off and found no swollen caps .....after doing some reading i pulled the wires going to the board on the left hand side(looking from behind)and the tv powers up and i get sound from the speakers.....now here is where i am stuck....i dont know what to check next.....any help is greatly appreciated

        the left board is the Ysus board and it has failed and is shutting down the supply board,on theses Ysus board it is the IPM under the big heatsink that fails and needs to be replaced only attempt this if you have the right tools or find a replacement board Flocko

              The IPM is extremely difficult to desolder - a basic soldering iron is unfortunately inadequate.

                You are going to have to check the y buffer as well, sometimes they blow together. I found a set of both boards on eBay for less than $100 and when I installed them, it fired up nicely......Except it had a thin black vertical line down the screen, bad plasma panel. So it's definitely a crap shoot with this model.
