Question about Hitachi 53FDX20B 53" Rear Projection Television

1 Answer

Magic focus --blue and yellow sag in the upper left area of the screen

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.

The Model# is 53UWX10ba - Colors off in upper left part of screen


The problem is with the convergence circuit. If you can solder, try resoldering the pins on the convrgence ICs. If that fails to resolve the problem, replace the ICs. These ICs will be large and black, attached to a heatsink and be marked STKxxx.

Update this with your progress.

Magic focus --blue and yellow sag in the upper left area of the screen


Hi, convergence circuit has failed, convergence IC`s and any burnt resistors will have to be changed, this is NOT an easy repair if your not very proficient at soldering and un-soldering components, you will also need a good (accurate) volt meter as the resistor(s) will have to be removed and checked for value and the values are critical to the circuit, ie: 3.3 Ohms must read within 1%, if you have the tools & soldering experience get back to me and I`ll tell you where to go to get the parts, if not you need to get the set to a tv shop, BMW Rider
