Z3 projector.3 years old. Blue tinge in one corner of projected picture. Grainy picture on dark scenes.


There may be some problem with your picture tube else try this that looks like retrace lines. Anyway, you should try to adjust screen pot not focus pot. Make sure you are turning blue screen pot (there are 3 focus pots and 3 screen pots) and do it slowly. If you turn it too much, it will affect your grayscale

Green screen


If the lines you see are retrace lines, It means that the 200VDC are missing and not getting all the way to the video amplifier assemblies.
Did you touch the screen control settings by any chance before you replace the HV splitter?

Projection sets have two very common problems.

The first common problem is convergence


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.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...


According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

Is a good projector able to perform well along a blue ray?


Hello the answer is yes, you can use a projector/projection television without losing quality. The only issue is the projector itself. If you have a good projector, It will look great. You need to check out the resolution on the projector that you want.


Hope this helps
