My sister's Hitachi 43fdxo1b has shadow images of colors. I tried to adjust the Convergence and it will not align. She had a repair guy come out and he said there is a couple items he could replace, but that it may happen again. He wanted a lot of $ and wanted to sell a maintenane package. Is there anything I can order and replace for her that is most likely the problem? what are my options?
The convergence IC`s board location are IK 04 & IK 05. Looking from the back of the TV they are mounted to a large finned aluminum heat sink on the right side of the chassis. The origional part (stk 392-110) can be substituted with an equivalent but higher powered IC (stk 392-180) , that is 180 watt instead of 110 watt chip. Do not use generic IC`s! Purchase origonal Sanyo chips only for best results. Replacement of the chips alone may not cure your problem if there are dammaged resistors caused by the origonal chips. Check the standing resistors on the opposite side of the heat sinks for proper value. RK42(2.2), RK46(1.5), RK58(3.3), RK52(1.8), RK50(2.2), RK54(1.5). All of these low ohm resistors are rated at 1 watt. If you encounter a bad resistor you must replace with the same exact value. Close is not good enough. This should fix your set. Do not buy a policy you have a good TV. Be sure to use a liberal dose of heat sink compound when insatlling the new chips, and clean off the old crusty stuff.

two colors see red and double
My upper left corner of my TV is showing up like a 3D image. the colors are overlaping. What can the problem be
My Hitachi, model 43FDX01B, seems to have the same color ghosting problem as mentioned here. I have red ghosting throughout the picture and in the convergence mode I have a distorted red vertical line to the right of center along with the blue vertical line and cannot converge it. Looks like I need to replace the convergence outputs also.

I HAVE A HITACHI 43 INCH FDX01B THE PICTURE IS OFF CENTERDHOW DO I RECENTERD IT?
I have a blue line 5-6 inches to the right of center. The line is not straight, but runs top to bottom in a slightly curved pattern. This results in a blue ghost picture (double image) 5-6 inches to the right of the main image. The convergence controls seem to work O.K, but the blue line does not move. It is fixed in one place.
Thanks
the color of my tv will not align
