That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
Thanks.

Go to menu then setup look for convergence if you do not see convergence then you have A open FUSE It will be on right side of FBT flyback transfomer there is 3 of them in a roll they are small brown rectrangler looking caps but ARE FUSES it will be the one in the middle. Replace it and you have a FIXYA.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.

zenith 55" projection tv. approx 8yrs old.
the right half of picture is normal the left half of picture is blurry or shows double or triple vision.

I would look for a lttle hrizontal potentiameter in the horizontal osc circuit.

or your getting hdtv signal now and it cant proscess it .

Dane,
The convergence amps most likely failed. That unit takes two STK392-010 amps and the most likely cause for their failure are one or more of the 3.9 ohm 1/2watt resistors out in front of the Ic's which have opened or changed in value. There are several of them too, Rz142,143,146,147,144,145,123,124,125,126,127 and 128 and do check them all...

Goto menu and look for convergence control and realign colors.
