Most possible cause is failed convergence ICs. Unplug the three wires for the convergence yokes then try powering up the set if it powers up the Convergence Ics need replacement

Toshiba 57H81 Rear Projection TV Problem


IT is possible that the power connector in the back of the set is either faulty or broken, you would have to go into the back of the set, and look and see in the connector to the power board isloose, if it is, then you might be able to resolder it on. If not, then there is a problem with the plug, try a different outlet.

Check all fuses in the power supply and look for any bad connrctions on the PCB. You are probably missing the 130 volt supply to the horizontal circuit. Common reasons are: Shorted horiz output transistor; flyback transformer, picture tube arcing , bad power regulator IC. In short, you need to get a qualified tech for this symptom. Hope this helps.
