Toshiba 50HX70 convergence problem

I have seen a few articles on this subject but I was hoping someone can give me specific help with this problem. I try to fix the convergence on mt Toshiba color stream (cinema series HD) model 50HX70, but I cannot set it up properly on the left side of the screen. The central crosshair, and all crosshairs on the right and middle of the screen are OK but when I try to fix the cross hairs on the left side, I cannot move the red color (I am missing about a half inch). I am including a picture to demonstrate this. Can anyone recommend a solution?

    Did any of the above posts try this and if so did it work? I have the same problem and am debating whether to order the parts and try to fix it myself (I am not so handy) or just buy a new tv.

Remote and volume not working on toshiba 50hx70 after changing out convergance chips

Howdy,
It sounds like you may have not have plugged something in or one the connectors are not "seated" or securely properly/tightly.
Make sure there is not any cables and modules are properly (tightly) secured and tightly secured.

Good Luck, big IRISH.

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 convergence

There are kits available online, which include the chips and the soldering iron too.......Just a word of caution, convergence chip replaced is more difficult on Toshiba #1 the chips face other boards that must be remove first. the main one is the convergence generator (which the sheild is soldered in placed) Also the signal board (which is what everythings mounted to is very fragile)..............Good Luck
