Im seeing duble words,how can i fix it?


Hi,
There should be a convergence adjustment on this set. It will have a "cross hair" type pattern
You adjust the beams so that the cross hairs turn white. I believe Green is not adjustable intentionally. The procedure is to adjust the vertical Red line until it alligns with the Green line. Then adjust the vertical Blue line until it lines up with the Red and Green. The line should turn White.
Repeat the procedure for the horizontal lines. When you return to regular viewing mode the double
images should be greatly reduced or eliminated..
Hope I've helped you,
Best Regards,
Mark

Power Supply failure.
NO YOu can not buy a "Powers supply"

You need a professional.
Stop using the TV until it is repaired.
Call the manufacturer to find you nearest authorized service center.

This is a vertical-deflection problem. Try to adjust the vertical (height and linearity and hold) controls, which should be screwdriver potentiometer controls on the back of the set.

If this does not work, a defective component in the vertical-deflection circuit will need to be repaired.

I hope this helped you. :)

1 inch lines on top and bottom of screen


Is the picture overall too small by 1 in. on top and bottom? Or is it cut off by the lines?

If it's too small, look for an adjustment labeled Vertical Height. This may only be accessible internally, it's normally a service adjustment, not a user adjustment.

Your problem is a vertical deflection issue, either an adjustment or the vertical circuit requires repair by a technician. In the latter case, electrolytic capacitors are a likely cause.

The same is true for rear projection. There may be an adjustment for vertical hold in a hole in the back of the cabinet.

Hitachi tv


One of your convergence IC's has burned out and needs to be replaced. A good rule here is to go ahead and replace both STK392-110 IC's with the new improved STK392-150's. If you have never replaced convergence IC's and realigned convergence circuits, allow a qualified tech to handle it for you. When I do a housecall for a set like that I charge $150 but shops in your area will vary so ask around.
