Hi Ray
have you had any luck with the service diagrams ? I have the same TV and the same problem, its completely dead, but fuse ok, and all components on both side od PSU board CEF286A ok, what else could I check ? I've checked a few places on the PSU and there is 220V ... just dont know what else to check
where should the 5v signal be ?
Thanks

Hi crashzero,
Best thing is to buy a new or used psu on ebay as suggested. Your board should be a vestel 17pw15-8 or buy the new boards 17pw20 v2
cheers
