you have some caps that have failed in the dm module
that will have to be replaced to correct the problem
if your know how to change them and have the tools the caps can be obtained through most electroinc parts suppliers

if you can change them let me know and i can give you locations on the board and the dm stands on the right side of chassis at rear

Radio shack wallmart all of those places sell the receiver

Same problem.. Checked the fuses but they're fine no reset switch to be found.

any flashing LED's when running service mode or convergence signal?

On this model the timer led blinks when the tv is off if you have the timer set to turn it on. You can get the manual here.
