    I've got the same problem - my tv just went off and I just have a blank screen. The light on front of tv seems to flip from red to green. Any ideas, without being ripped off?

This happened to mine. It was a fuse that cost $3.42 but the service call was $200! If I knew how to do the freaking work I'd be rich!

No pic or sound with power on my Toshiba 50HX70 Tv


The plug configuration shouldn't make a difference; the third (round) pin is only an earth/safety ground. The two primary plugs supply the AC. You probably have a failed power supply which may be a separate board. Check to see if this is the case, look for a part number and see if you get any hits on it on search.

50hx70 blue projection light is concaced at top and bottom of tv


When the convergence amplifier ICs go bad (STK392-xxx), they RARELY cause more than one color to go out. The fact that the top and bottom of the picture are effected indicates the vertical convergence IC. Replace both, and while you're in there check the bias resistors... it is likely one of these is open. Once the ICs have been replaced (as well as any open resistors), customer convergence followed up with the auto convergence should do the trick.
