The colors are not matching up it will not allow auto focus or manual, the red line is not straight? Toshiba 57H82 rear projection t.v.


The convergence circuit has failed in the tv. These are the big STK chips on the circuit board. It typically costs $300 to fix at a TV service center. Requires replacement of two STK chips, some resistors, some fuses and then re-alignment of the CRTs within the service menu.

If you have proper soldering tools and can download the service manual, it is possible to do the repair yourself.

If you do not have any electronic background whatsoever, I do not recommend a person to attempt it.

When the screen is dark there are lines that run back and forth across the screen which is only noticable when pitcure is dark immage.


the screen bias needs to be turned down-ehind the front cover which is behind the grille there is a small black square about 3 inch square 6 little knobs sticking out 3 say in small letters screen and 3 say focus, don't adjust the focus just the screen for the coresponding color that shows up when picture is dark.best way to do this is darken the room and put it on video input with no signal if lines are white slowly
adjust 1 color after the other counterclockwise untill
lines disappear if only 1 color shows then only adjust the knob with the matching color. this is a very fine adjustment, to much will make your auto focus stop working. check it after you are done

Hitachi 51F500 magic focus wont work, blue has "dropped", when I use the magic focus on auto it does nothing, when I use manual focus the grid has the blue scooped down and I can't seem to get it back in...


Sounds like your blue convergence module is faulty along with a few resistors. There is two convergence modules in your set(stk-392-020) and when one fails, the both of them are usually replaced with a matched pair .If you have a good knowledge of electronic you may replace them yourself.otherwise you`ll need the help of a tv repairman. Hope this help. Good luck

Screen prob with Hitachi 51UWX20B red square


Maybe the best way to adjust the screen is with the manual magic focus..instead of letting the tv do the auto change it to manual and see if you can adjust the convergence yourself. I have this same model and once in the manual adjustment you want to make sure you see all white lines....if you seen any blue or red that is the color that needs to be moved towards the white line closest.

Once you think you have it lined up nicely hit "exit" on your remote and option 1....

Hope this helps you.

The red projection tube won't focus


Set needs convergence ic's changed and possibly a few small 1/4 watt resistors. Parts have to be desoldered/soldered into circuit board and test equip.(ohm/ volt meter) is required. Most repair shops do this repair for 175.00-375.00 Hope this was helpful. Russmann
