I changed my two IC chips and three resistances on my Hitachi TV to fix color alignments. Now the problems is that yellow and blue double image are seen at the bottom of my screen with no much effect on the rest of screen. Manual convergence show a white horizontal and vertical lines with focal right horizontal end with red line no aligned, but if I fix this side, the left side is disaligned. So, I am lost. What can I do?, what is wrong?


Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

the tv looks like it is in 3d. when i try to adjust the convergiance the plus signs on the left are bent


do not play with this tv replace the stk ic chips and the resistors around the stk chips ,cant miss em about 2 inches big with heat sinks on them.

unable to perform convergence.


Ur 2 STK convergence ICS,and some or all it resistors are dead.U must know how to solders?Replaced the 2 STK convergence ICS and some or all it resistors,will auto focus ur convergence back to normal buy itself.Tries websites like Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.

convergence


did you replace the convergence resistors with the ICs? The resistors often get increased resistance when the ICs go out and if they dont get replaced you can have a next to impossible time adjusting the convergence properly, as they have to be within 5% tolerance. You can get the resistor kit for your JVC at the following link. Its Called JVC convergence resistor kit #1. Heres the link.
