Question about Zenith Projection Televisions

1 Answer

I have a zenith pvr5263dt projection television.when I turn it on the color is out of alignment, I go to the menu and in one section of setup cross hairs come up with the colors misaligned but it does not show you how to align them so they blend together as one instead of showing all three colors

    Thank you for your quick response Dan.

    Yes I would like to repair the problem, my major in high school was Radio and Television repair but that was a long time ago but I can still solder so if you will provide me with the detailed instructions I would greatly appreciate it.

This is a convergence problem and is either bad connections at the convergence ICs or defective ICs. If you can solder, you can fix this yourself. Please let me know if you wish to do this and I'll provide more detailed instructions.

    Ok. Open up the back and locate the convergence ICs. These are the large black on es attached to a heatsink. They should be marked STKxxx. Try resoldering the pins on these first. If that fails, replace them. If you need to replace them, check in the same area for low valued resistors and/or pico fuses that may have opened up as well.



    Keep me posted.

Zenith rear projection tv, left 1/3 of screen has color shadowing like colors are not aligning...tried adjusting with setup menu, but didn't work


Projection sets have two very common problems listed below. bb0cf99.pngYou can see some more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

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

Colours out off focus


There should be a section in your menu that says "convergence". Select that and use the arrow keys on the remote to align the colors with the white crosses. You will have to do it for each corner of the tv. Otherwise you may have to replace some boards inside of the unit, which can be expensive.

My zenith big screen tv is out of focus and we cant find any master focus control. How do we fix the focus?


It is unusual for a rear projection to be out of focus since the projectors are fixed. But, it is common for the projectors to be out of alignment, in which case the picture will look like a bad 3D movie of yesteryear.

Go to the setup options / menu, look for the ALIGN option, follow instructions on screen.

Cannot reset vertical convergance


The most likely cause is shorted convergence chips and possibly a few pico fuses.

If the convergence on one or more color does not align using the convergence setup procedure, that means that one or more convergence ICs must be replaced, that is the reason why you get bad picture.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.

My colors all of a sudden went out of wack


Is there an advanced convergence setup anywhere in the menu where the screen displays a grid? If so, you might want to get into that and move along the grid to each section that looks off. Adjust until the color falls behind the gridline, and move on to the next. It can be a time-consuming process, but should take care of your convergence issues.
