Question about Toshiba 50HX70 50" Rear Projection Television

1 Answer

Im having a convergence problem with my 50HX70. The tv was working fine until one day i turned it on and there was a blue shadow on the bottom half of the screen. I tried to adjust it and the horizontal part of some of the crosshairs is at an angle instead of being horizontal. Do I just need one ic (stk392-110) for the blue lamp? Or could it be something else? Where is the ic for the blue lamp located?

Red and blue overlap shadowing


Sounds like a convergence ic problem, normaly i tell people to replace the ic's but in your case try to re-solder the pins on the ic first, you may just have some pins broken loose from the board. Locate the stk392 ic's there will be two of them located on a heat sink, unplug the tv and get to the bottom side of the board and re-solder the pins. if this does not work, then replace the ic's

Colors shadowing eachother, adj convergence, but will not save.

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.

Toshiba 56H80 Convergence Problem?


There are 2 large IC's in your set and one of them has burned out. These are called convergence output IC's and are usually the STK392-010's. A good idea would be to go ahead and replace both with the newer, upgraded STK392-150 IC's. A good tech can change those IC's in about an hour and a half, and when I do a housecall for a set like that I charge $150, but shops in your area will vary so be sure to ask around.
