Re: LG 42" LCD TV 42LG20-UM No video ONLY sound BAD inverter board or bad power boa
Hello, I'm sorry to resurrect this thread. I have a similar issue with an 42lg5010. After reading this thread and testing the fuse on the master inverter board it seemed to be faulty. I attempted to replace it but it was too small so I just bought another inverter board off eBay. Like for like swap. Now when I turn it on the screen comes on for 2 seconds then goes off and I can continue to hear the sound. Before I changed the inverter the screen wouldn't even come on. Now I have the 2 seconds to black problem. Any suggestions on what to try next? Obviously the fuse had gone on the master and now with the new board it's ok but there's something that's making the screen switch off.
Please help I'm tearing my hair out!!!
Thanks in advance
