Coby LEDTV4028 and LEDTV5028

[jstiene]

Hello. I have each of these Coby TV's sitting here, brand new, dead. 40" doesn't power up, and the 50" will work periodically. No parts seem to be available. What I was wondering is (1) has anyone else worked on this with any experience as to what their typical problems are, and (2) are these parts used in other brand TV's? Trying to determine the effort I should put into these...

Thanks

Joe
