Hi Steve, I currently having a problem with the same Sanyo model dp50747 (manufactured in 2007) but was wondering if there are any similarities in the problem I'm having with my TV and the one you were having with yours. Mine will power up normally where you can actually see the small green power indicator illuminate at the power button and then screen change from black to a gray color. But I get no sound and cannot access the tv menu. TV Repair tech came out and estimated $400+ (includes $80 service call, parts & labor) to replace the 'main board', which I assume is the power board, but said he didn't think the board that is needed was even made anymore for this model. He also said the refurbished replacement would only carry a 90 days warranty. So, if it's not the fuse(s) that have gone out, I'm going to have to make a decision to $400+ to try and fix a TV I can't get parts for or just scrap it out for usable parts. I hope it just a fuse(s). Thanks for sharing you success. Greg 07/23/11
