Toshiba Regza LCD TV DEAD SET No Power Circuit Diagnosis & Board Level Repair (55ZV650U and others)

In this video we'll diagnose a dead Toshiba Regza 55ZV650U television and repair it together. The symptoms that this video is applicable to are when the TV will not power on from either the remote control nor the manual power button on the side of the unit. And that unplugging the unit for a period of time still does not restore normal operation. If these are your symptoms, then this video may help you do the repair yourself and save money.

While this video shows the 55ZV, the electronics diagnosis and repair approach for this common problem is also applicable to these other Toshiba TV models 42ZV650U, 42ZV655U, 47ZV650U, 47ZV655U, and 55ZV655U.

WARNING: Electronics diagnosis with live AC voltage can be hazardous. Practice safety protocols at all times and wear appropriate personal protective equipment.
