Blue/Yellow out of focus on Hitachi 43UWX10B

Please help me! My screen is out of focus. There are blue and yellow lines that highlight everything on screen. Red works fine. I have tried magic focus to no avail and am trying to figure out how to manually focus the set. I have reviewed other solutions to this problem though none of them allow me to get the color 'grid' everyone speaks of. I have tried pushing 062597 status to get the grid and all that does is change the chanel. Thank you in advance:)

B+ resistors checked and then magic focus activated......T.

You have a defect in the convergence circuit. Both chips will need replaced and possibly a resistor or two. Chip part numbers are STK392-110. Typical repair runs around $350

Blue screen w/ lines - called for repair

Good Day, cyndycallie;;
I'm glad you asked here. but if you have a blue pix with lines in it, then it could be that device. It also could be something else. Why not have the previous Company install the part? (PAUSE) If you don't trust this Co. ,have another come out and confirm the problem. Plus, if they are wrong it will cost them NOT you. Please call a Factory Authorized Service Center. Good Luck, big IRISH. PS come back if you need more help. I will even talk to the service Co.

HITACHI 43UWX10B Color Convergence

Good Day,

Sounds like the TV's convergence circuit has failed:
*Call an Authorized Service Center and them give you an estimate cost of the repair, or
*Repair it your self; get KIT 10 locally or B&D Enterprises
Good luck, big IRISH.
