Question about Hitachi 43UWX10B 43" Rear Projection Television
Magic focus does not appear to be working it gets to RED and stops with a set of bars on the left then it shows the number 4 bottom right corner
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.
I am here to help people--
