Question about Zenith R56W36 56" Rear Projection Television

1 Answer

Shadow Today my wife said she could smell something from the TV. The words and some graphics appear to have a shadow. Just like you would select a shadow with fonts on a graphics program. Usually in colors of blue and yellow. Thanks for any help.

    The picture isn't foggy. I'm pretty good with Technology. I'm a Cisco Eng. Can I purchase a board or amp? If so do you have any suggestions on where to get one?

    Thanks again.

    Thanks again by the way the TV is almost 4 years old.

Nice description. Is the picture still square or does it have like an hourglass shape to it? If so, one of the convergence amps has failed (common problem) and needs replacing as well probably the fuse resistors feeding power to it. Probably a job for a pro as it needs to be reconverged afterwards. Can give you DIY instructions if you are OK at soldering.
Is the picture foggy as well? Have him replace the crt fluid while he's in there. How old is this TV?

    The amps are standard STK392-570 modules. Can get them at

    MCM electronics or Andrews Electronics.

    Could also just do a board swap with Module Exchange at 972-298-1212.

    I encourage you to download the service manual from one of the sites that advertise on Fixya as you'll need it sooner or later.

Since installing this graphics card I've had a shadowing issue. Being a new graphics card I assumed it was a problem with my power supply. I replaced the power supply and I still have a shadow on every...

Maybe the new card supports more of XP's graphical features and the shadows might be a feature.


This border on desktop icons can be created when the desktop items have been locked, to unlock the desktop web items right click on an empty area of your desktop. Now select Arrange icons by and uncheck 'Lock web items on desktop' if it has a little tick next to it. If you did not have a tick here then Right click on your my computer icon and view its properties, now click the advanced tab and then on the settings button under performance. Now on the visual effects tab scroll down the list of effects to 'use drop shadows for icon labels on desktop' and put a tick in the box next to it, then click ok. This should remove the shadow border from your desktop icons.
