Question about Zenith Televison & Video

1 Answer

In the past 5 minutes, the picture on my Zenith R45W47 rear projection TV has gone blurry and dark - with a lot of orange and pink... I don't have the least idea what to do to fix the problem, but I know it's not the cable connection.

    As I've been watching, it seems all the colors are off, and it seems to depend on the image on the screen as to whether the colors are more orange/pink and/or green. I'd just like to make sure that this still indicates that the convergence out section has gone bad.

    Thank you.

    Here are a couple pictures of the screen.Sorry they're not clearer, we had to do this with a phone camera... but it gets the colors across....

    I would be willing to work on the TV myself, but can you direct me where to get the service manual and other necessary materials?

Hi,
It seems that TV got problem in Convergence Out section and causing blurry and dark picture with orange and pink shades. This happens when Convergence Out ICs got bad.
You need to replace 2 convergence out ICs in TV that are available HERE with detailed instructions, how to replace them. Convergence Repair Kit price is $72

    Thanks for images.
    It is not convergence problem. I withdraw my previous solution.

    This is Low Cathode voltage supply problem and few electrolytic capacitors seems weak / leaky /dry in power supply and deflection section of TV. I would test 200 volt supply going towards cathodes of 3 CRTs in TV.

    If you are comfortable with TV repair then get service manual of this TV and replace electrolytic capacitors in deflection section of TV. I hope 3 or 4 capacitors would be replaced.

    Thanks.

    Thanks for update.
    You can download Service Manual from HERE for small fee.
    For required parts, I would recommend Part Store and Electronix
    Please type part number as per service manual in search box on above part stores website for price info.

    Let me know for further query / info.

I have a 1994 zenith big screen the picture is showing really dar


It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.

I have a Zenith 65 in. TV model #R65W28 serial #271-33220211. The words are blurry and there is a green outline on images in the picture even if i reduce color to black and white. what can i do to fix it?...


It sounds like the convergence drive circuit has gone bad. When that circuit goes the red, blue and green don't line up properly. Have a repair shop check it out. While they are in there have the shop clean the lenses and mirror.

Blue wont alaign


If the blue will not align then most likely you have a convergence ic that has gone bad and maybe some of the low ohm resisters that are next to it.

My tv is blurry, showing green and red waves...zenith d61w25


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,Panasonic2_bing.gif,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...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

Sony rear projestion TV has blurry picture.


sounds as if your convergence needs to be set. either through the menu on the tv or remote you need to get to the convergence set screen and you need to line up the crosshairs. this usually happens when the tv is moved or bumped.
