Toshiba 50H81 access to lenses

I just repaired a Toshiba 50H81 and want to clean and re-focus the lenses. I have a service manual, but I cannot figure out how to open the unit to clean lenses and adjudt lens focus. I can remove the front screens, but this does not allow me to focus the lenses onto the screen. Anyone know how to open the back of the case?
Thanks,
Dan

Convergence problem


Replace the Convergence amplifiers. Mine did the same. It was like watching a 3D movie without the glasses. It is not hard to do for someone who knows their way around a circuit board repair. Otherwise call a reputable service shop.

Camera won't shoot with lens on Auto Focus


Talked to canon support, they suggested to send lense in for review/repair. They said it could be the motor, I think it was a gear problem based on the noises and jerkiness of the focusing action while in manual focus (manual focus gave out as well). Cost TBD - "would definately be more than $50. I shopped around and elected to buy a new lense rather than try to hassle with the repair, shipping, insurance, and the wait, etc. Besides, I have a deadline that I need the lense for, so repair at Canon really became a non-option. I think the cost would've been pretty much the same in the end as the new lense, since this wasn't one of the costlier of lenses to begin with.

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!
