I hope someone helps out with this one. 
Similar problem here on same model. 
I know that a quick off/on of electricity in the area preceded this issue on this set. 
Unlike WILLYAM1, I am unsure of the voltages on the PS. 
Will be testing tomorrow. 
First fuse outside immediately next to the power plug. 
Second fuse immediately next to the input on the PS. 
any HELP is appreciated ( or maybe it is just the fuse )
