Question about Hitachi 51GWX20B 51" Rear Projection Television
I replaced the Convergence IC chips, and also checked all the resistors to see if they were in tolerance. One was bad, so i replaced it.
The convergence is so much better, but is still off by about 2 mm. especially the blue! I wanted to go into the service menu so i can refocus the tubes, because the geometry screen is the best signal i know of to do that to. i might also want to just corect the geometry and reprogram the magic focus.
Does anyone have the service code to the hitachi 51gwx20b?
There is not a Service code to Enter into convergence on this set , on convergence board there is a switch on the very front of board WITH set on press and hold 3secs you should see convergence Pattern Appear after you release button. From the Front of TV remove Bottom cover then you will be able to see whole chassis,and the Little Blue contact switch.on same board you replaced ICs.
