Question about Hitachi 43F300 43" Rear Projection Television
I replaced the convergence ic 392-110 with a hitachi updated piece 394-160 and have the same problem. Everything is plugged in correctly and nothing wrong with solder job, resistors do not look burnt. Dont know what else it could be. The screen still looks the same3d looking and the manual adjustment screen all the red lines are bent the top 3 red lines are bent way down to the left and the are off and bent at the ends. The cursor on the manual adjust screen is supposed to be white or red,blue. The cursor should be white but it is spread out alittle you can see green red white until you change it to red or blue. Any help would be appreciated. Thanks

It looks more like an open solder because you were able to align it properly after replacing the STK ICs, if there was an open resistor(s) you would not be able to get it align.
I would suggest to go back and double check the solder joints on the STK ICs as well add some fresh solder to the resistors nearby the stk392-180.

SOURCE: Hitachi 46f500 convergence?
a common problem wich i also have with convergence with blue and red convergence.
the image converge amplifiers are burnet out wich in turn blow out resisters that control individual color convergence.

The fix is that Hitachi is a POS. It's kinda like a FORD product, found on road dead. There are problems all over the internet with Hitachi TV's. I ain't gonna give up on putting them down until they fix my 3 1/2 old TV with most of the problems you people are describing.
