Question about Hitachi 53FDX20B 53" Rear Projection Television
I followed the instructions for Magic Focus, but nothing changes. The blue
will not align. We are in a remote area, no access to repair within 75 miles. TV has worked fine up to about 1 hr ago when the red and yellow elements no longer align. Magic Focus is run but does not fix the issue. Towards the center of the TV the piture is more together, but everywhere else the colors concave in towards the center.
This is a problem with the convergence circuit. If you can solder, you can repair this yourself. First try and resolder the pins on the existing convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs.
