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.

Will not focus

The set has a problem with the convergence circuit. If you can solder, try resoldering the pins of the convergence ICs. If that fails to resolve the problem, replace the ICs. These ICs are large black and attached to a heatsink. Thay should be marked STKxxx.

Here is the schematic diagram. Download all the 13 parts and unzip them using winrar.
The parts you need are listed on page # 50 of the schematic diagram.
You will find the ICs HERE.
Make sure you check the fuses and micro/pico fuse nearby the ICs, as well some crystallized solder joints.
Good Luck.

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
