The 3 colors are not ligned up and the picture is out of focus. We tried the flash focus and that did not work. we tried the convergence but are unsure on how to use it.


Colors misaligned in rear projection tv due to failure of convergence output ICs and replacement of bad ICs will solve your problem, it needs soldering work in tv circuit board with proper tools, if you are handy with electronics stuff repair ad can replace parts in circuit board then let me know to provide you more info OR contact local tv repair shop to get tv fix.
Thanks.

Convergence issue. The sony type 1 convergence kit from www.tvrepairworld.com should repair that issue. The kit contains the parts and CD with instructions.

Colors far out of convergence, and image is warped (bowed)


it sounds like bad solder connections on the convergence IC's if you do not resolder them right away the IC's will blow out then you wil;l have to replace them. Good luck

How do you adjust the fine grain convergence on an hitachi 53hdx01b?


Hello,
Your problem description is not clear.May be you have convergence problem with your unit.
Press flash Focus button on the control panel of the unit.If the flash focus complete one full cycle there is no problem with convergence amp.
Inorder to adjust convergence you need to enter the unit into service menu.

Good Luck

Good Day, Martin Ping;

Picture won't merge? It sounds like your TV has had a failure in the CONVERGENCE CIRCUIT by replacing those IC's should correct your TV's problem.

Good Night and Luck, big IRISH.
