1 Answer

Hitachi 43fwx20B Same red blurry issue that everyone is having. After I run magic focus it get stuck on the red and stops. A number 5 appears on the lower right corner of the screen. Do you know what that means? A code of some sort?

    I do have the same problem. Magic focus started and suddenly jam on color red a few seconds and the number 5 appears at the right bottom of the screen. Then there's always red flickering lines in the picture.



    How much STK392-150 chip do I have to buy? Is it easy to fix?

Good Day, firstshot;

This is a common problem with this TV, but there is an upgrade to correct the CONVERVGENCE circuit problem.
If you want to repair this concern yourself: Contact: B&D ENTERPRISES,
1-800-458-6053, www.bdent.com and ask for KIT10 for your Hitachi TV.
If you want some else to do the repair for you call an Authorized Service Center.
Good Luck, big IRISH.

Colors are not aligned Magic focus ?


The magic focus will stop if there is a bad sensor and or a problem in the convergence circuit.

This set uses two STK-392-110 convergence chips--both along with any of the resistors that protect them need to be replaced and the set adjusted--I have repaired hundreds of these sets----


Confirm model number----and if you go into the customer menu and either red or blue will not move in any or some direction--the chips have to be replaced---LET ME KNOW WHAT YOU FIND AND I CAN GIVE YOU FAIRLY DETAILED INSTRUCTIONS ON WHERE TO GET THE PARTS AND WHAT IS INVOLVED IN THIS REPAIR.

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.

Make sure you check the fuses and micro/pico fuse nearby the ICs, as well some crystallized solder joints.

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
