Question about Hitachi 53UDX10B 53" Rear Projection Television

Convergence I have a weird problem on my hands. First I tried magic focus but it would not go past red and displayed a number 4 in the corner. Then I went into manual convergence and I noticed that red and blue would not move. After researching on the internet I found out that the most likely culprit was the convergence ICs. I bought 2 new ICs and installed them and when I turned on the TV the power LED started blinking. I removed the new ICs and replaced it with the old defective ones and the TV turned on with the same convergence problem. All resisters and so on look fine and tested good with a multimeter. Any help is greatly appreciated.

Your going to need to check the schematic and check the b+ going to the IC's as there maybe a bad capacitor. When the new IC's are installed it loads down the set or power supply. Its the bad power supply or the IC's are defective, but im thinking the power supply.

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.

IMAGES ARE OVERLAID AND NOT IN FOCUS

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
