Have you tried to adjust the convergence? If you can't get them to line up then you may need to replace the ICs.

I got a Zenith Z56DC1D the bulb was replaced and its clean. I have blurry picture and it seems out of alignment there is a large black stripe on bottom and the top of the picture is cut off. How do I fix...


Without seeing a photo it sounds like the picture is letterbox with top and bottom black areas---if not that it sounds like a possible issue with the optical light engine the set uses to project the image on to the screen----most of this is not customer repairable.

Picture is blurry


this is a problem wit your stk392-110 convergence IC's - One has gone bad and the both should be replaced. Also, check the large resistors near the convergence IC's - it sounds like one of them may have burned up..

Arcs at the Top and Bottom of the screen!


You will find small 1/2 or 1watt resistors close to the ic's, you must measure them and they must be exact ohms. I believe you'll find a couple open or have changed in value, I hope the new Ic's haven't been fatigued. That should fix your problem.

RED GREEN BLUE Then this is suspect will be a convegence problem. which 85 percent of the time is what is know as convergence ic chip failure. a electronic part replacment. are you a tech or know how to solder. any experince would be helpful but i would have to admit this really is not a job for non techs there are setup issues. at our shop the cost of such a repair averag 135 to 250
