Sylvania 27" color TV blows fuse imediately when powered on?

Sylvania 27" color TV blows fuse imediately when powered on. Looking for schematics to troubleshoot the problem unless someone has had this problem and can offer a solution. The circuit board number is BL2700F01012-1. Thanks for your help!

I had the same problem as you, and was able to find a bad diode in the bridge rectifier.
