Hitachi 43FDX01B green is out of whack


The green is not adjustable in the customer menu because it is considered the 'master' color. It is adjustable in the technician mode however but if it is curved it won't even adjust properly that way either. The problem is the convergence ampifier responsible for green convergence has failed. The convergence output IC's need to be replaced.

Convergence lines on the Hitachi 43FDX01B


Download this manual:-

http://schematicsforfree.com/archive/file/_newly_uploaded/Hitachi_DCAM_Manual.pdf and do the Red touch up on page 63. However I would read the rest of the manual as well so that you get the full understanding.

If you still cannot converge the Red then you will need to replace the two Convergence IC's and associated resistors. Details of how to do this are here:- http://www.digitalhome.ca/forum/showthread.php?t=21847

Remember that there are VERY HIGH VOLTAGES present in an RPTv even when it is disconnected. So disconnect it from the mains for at least 4 hours before you enter the set, this will give time for the high voltage to discharge.

Good luck!
