Could be bad amps - or a yoke return resistor is out of value. Need to get out the meter and test the resistors out in front of the amps for true value..

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.

If you have the wires switched GEEN,BLUE,RED on one end the color will be wrong. Check that the color off the wires are matched. Try a new cable. I've seen this a lot.

If the tin can module you are referring to is the hyper module, it is common to replace all 11 caps because the factory caps ****. Check for bridged solder connections at STK's search the forum at electromaniacs for 50h81 :)

57H82 convergence issue, but not STK IC


There are probably eight to ten resistors sitting behind the heat sincs the Chips mount on. You will need an Ohm Meter the easiest way to check them is just compare them with one another, you will see a pattern then you will see one that is really high or open (infinity) that is the one to change check the coor code on it to be sure you replace it with the right size
