Question about Toshiba 50H81 50" Rear Projection Television

Toshiba 50H81 manual convergence


I have a toshiba model 50H81 CRT type rear projection TV. Just bought it second hand and it appears that the red tube is rotated slightly from the other two which causes the red convergence to be bad at the lower left of the screen. Adjusting the convergence on the menus works for overall convergence, but because of the rotation the red will always be misaligned at one corner or the other.

I have removed the panels to be able to see the yokes of the tubes. The question is: what is the best way to rotate the red tube to get them all into alignment?

Re: Toshiba 50H81 manual convergence

Are you sure it's yoke? these are know for bad convergence amp ic's
other wise it's a screw and glue holding the yoke in place loose the screw and try to break the glue with out breaking the plastic on the yoke, the other thing you can do is adjust the magnets which have tabs on the yoke. i would mark the position's of everything on the tube with a sharpie so you can get it back to start.

The red will not line up when it is in the

You have a yoke and screen voltage issue with your red crt tube. If the red moves but not enough to do the convergence then you may be able to adjust the red crt. If the red doesn't move at all when you try to do the convergence then you most likely have bad convergence IC chips that need to be replaced. They aren't expensive, the last pair I did cost $36, but it involves taking the set apart and doing some tedious soldering. If you have no experience with this sort of repair you may want to go to a shop, They will charge $300-$400 to replace the IC chips. If you want to try this yourself post back and I can help point you in the right direction.

Toshiba 50H81 TAC0151 Blowing Fuses, I Need schematic

Well without the schematic, knowing Toshiba they have alot of convergence problems, so see if the fuse blown in the convergence area, if you you may have to replace convergence amps. These are the big STK's. Most of the time there was a color problem with set before going out. If no problem with this on your set then look in the HV area Hor. and Ver. area. Hope this helps!
