Hitachi tv magic focus does not work


Your problem is the convergence circuit. This is very common in CRT projection sets like yours. There are a couple of IC's that need to be changed and possibly some resistors. A good repair shop will run you $400-$500 to do the repair.

Not focused


Convergence IC's need replaced. STK392-150's at location IK04 and IK05. There may be some resistors in the circuit fried as well, they will be visibly baked. Email me if you need the resistor values, i will need the board locations for the resistors to get you the info.

Out of focus


Rach, if it doesn`t move from green to red to blue in Magic Focus then there is a problem with the convergence IC`s and probably one or more support resisters. These components will have to be replaced, questions? ask away, BMW Rider

Hitachi 61SDX picture got dim shows Code 3


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
