Re: Vizio P50HDTV20A No picture No sound

Found a leaky cap and a blown fuse on the Y SUS board. Picked up parts today. Set powered up fine and looks great. Thanks for the Help.

Cycled thru inputs. Yes your right I do have sound I missed an obvious step... thanks! I guess that puts me off in a different direction. I'll pull the YSUS board and do a good visual inspection and check out as many componants that I can. Does anyone have any info such as test points or voltages? What about the adjustments on this board .

I searched all the previous posts related to no picture on these vizio models and most if not all of them point to the Y SUS board. The differance with the unit I'm working on is that I also have no sound. I'm not a person that is fond of the shotgun repair method of replacing parts untill you find the problem. This set is worth maybe $500 at best so I'm not going to start throwing $100 boards at it.
