I have a 43" hatachi

I have a 43" hatachi projection screen had the hour glass look replaced the STK (2) IC'S and hour glass went away but my blue wont move over to red and green only in the middle of screen. Had a repair man come out and told me the same thing i already did and could be the STK IC'S or is there something else to check?

Yes, your Convergence ICs have failed. Replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu.

Hi , i will suspect your convergence board is defective you have 2 ic call stk for convergence correction and pin cushion
and some low value resistor and different bad soldering ,all this needs to be replaced and then reajust ,you must have a digital
array button on the front panel button some an automatic set up call majic focus wheres you must be able to realing this but if you dont have this button is probably locate on the convergence board anyway the circuit needs to fix befor any attempt to make any adjustement ,you may need a tech to do it, ic cost about 20 box each theres two on the board and s its an hour jobs about , depend on the tech experience...
hope that will help

42 inch Hatachie Ultravision model 43UWX10B and


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--

Convergence


i have tried this replacement on philips 43 inch. convergence ic part # is STK-392-120. it is mounted on a big heatsink, replace this 2 IC at one time. soldering is not difficult. 1. you need desoldering tool (**** type) 2. soldering iron of 40W 3. and silicon grease for greater transfer between IC body and heatsink. i bought that personally in asia for less than 50USD on two IC with same part # . let me know if there is any other thing i can do.
