PICTURE STUCK ON ONE CHANNEL, GHOST CHANNEL OVER THE TOP OF THAT AS YOU CHANGE CHANNELS...STILL SEEING THE CHANNEL THAT IS STUCK IN ONE PLACE... 55 INCH HATACHI ULTRA VISION....


This is called image burn, or image retention. There is no cure for this. The image has been burned into your picture tubes from having the same image tuned in for too long.

The magic focus will stop if there is a bad sensor and or a problem in the convergence circuit.

This set uses two STK-392-110 convergence chips--both along with any of the resistors that protect them need to be replaced and the set adjusted--I have repaired hundreds of these sets----


Confirm model number----and if you go into the customer menu and either red or blue will not move in any or some direction--the chips have to be replaced---LET ME KNOW WHAT YOU FIND AND I CAN GIVE YOU FAIRLY DETAILED INSTRUCTIONS ON WHERE TO GET THE PARTS AND WHAT IS INVOLVED IN THIS REPAIR.

I am here to help people--

Need to clean lenses and do manual focus/alignment of guns on a VS-5055. How do I get access to them and adjust? Thank you.


the lenses are accessable by removing lower back of unit,clean them with a damp paper towel-wipe them off with a dry one.put back back on unit.
screen/focas controls are in front of unit.remove speaker grill remove black cover using phillips screwdriver.you will see 2 sets of controls.one row is focas.one row is screen controls.red,green,blue.turn each focas control slowly to get the clearest picture for each color.screen controls are touchy(if you turn then too high unit will shut off)if the black and white picture was good i would not adjust screen controls.if it was bad turn blue and green screens down all the way.picture is now red turn green up until it turns yellow then turn blue up until it turns white

Pictures not lined up and angled


Sounds like your convergence is just out. First make sure the mirror in back is pulled out completely (if you have that model). Otherwise, there is a convergence feature on the menu that should fix it all.

Sounds like there is a problem in the convergence circuit. There should be an on board cross hatch and controls to adjust the lines to a white line. If these control wont adjust then the power ICs in the convergence circuit are most likly bad. if you know how to solder and know how to replace electronic parts then get a service manual find the part #s and order the parts . If you dont know how I can teach you here sorry. But I will tell you that a repair like this will run about 300 to 400 bucks to repair. Good Luck
