Question about BenQ PDP-46W1 46 in. HD-Ready Plasma Television
I have a 55HDT79 that have no picture but sound OK. I replaced Power Supply Unit (HA01751). As from basic troubleshooting flow chart, all five LED on Digital Main P.W.B are turned off after program is loaded, that means no error.
Still, there is no Va(60V) and Vs(80V) coming out from the Power Supply Unit (HA01751) to drive the screen. I have the unit just over one year and a half.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
