Question about Hitachi 53FDX01B 53" Rear Projection Television
While attempting to adjust the convergence on my Hitachi 53FDX01B the red convergence will align vertically but when I attempt to align it horizontally it tilts from left to right instead of aligning evenly. For example if I press up on the remote to bring the red convergence up, the right side will go up but the left side will go down, this problem is most noticeable on the sides of the screen, when the right side is aligned the left side is completely off of the green and blue convergence lines. I would like to attempt this repair myself as I've had experience with computer repairs, however I've never attempted a TV repair before. Any help or advice is greatly appreciated.
For your hitachi unit one of the convergence IC is bad along with couple of low value resistance on
the convrgence board.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then yourconvergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
