Hi there!
You would need the manual to adjust the convergence. First to correct the curving and then to line up the colours. Not too sure wether you need a service remote or the one that came with the set. If no adjustment takes place when you adjust, replace the Convergence Amp IC'S. Good luck,JUS004

The picture on our tv just went like it is curved with alot of red and green tones in it. Is there something I can adjust to correct this?


The description suggests a convergence problem. Can you update this with the model number please? This number is required so I can provide you with the correct parts that will need top be replaced.

Thanks,

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.

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

If it is truly a 52 inch standard projection set (you have it listed under 32V420T which is not a projection TV) and your 3 colors (red, green and blue) are no longer lining up and are all curved on the sides, then it means that your convergence power supply has stopped working. Post the actual model and chassis number and a better description of the picture here and I will be able to assist you further.

Red & Green seem "off centered"


Your set uses the 195 series chassis, which has separate components for each of the 6 convergence channels and a separate power supply for the convergence circuits. If all 3 colors have drastically shifted, especially around the edges, then chances are your convergence power supply has stopped working. This is usually caused by the failure of the STK730-010 switching IC. If one of the colors has dramatically shifted by itself then something has stopped working on the convergence board. Sometimes I see CRT coolant leaking onto the convergence board as the cause. In either case this is something that should be repaired and realigned by someone experienced with RCA projection TV convergence circuits.
