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.

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.

Shadow top to bottom of screen on left side about 2" wide...


This can be the sync wheel assy, failure in the drive circuit for the display chip, or an illumination fault. You will have to give the set out for service.

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

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.

How can I fix my 56" widescreen jvc


ok. let start this process. are the colors seperated? 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
