Question about Projection Televisions

1 Answer

There is an old zenith projection TV, and the 'convergence correction' paper on the side of the inside of the TV has a series of 6 or 7 LED's all green except 1 red one. the red one is on, and 2 of the green ones are out, the audio and tv ones to be exact. what would this mean?

    the 'convergence correction' paper is a layout of the LED's and power supply on the computer board, and shows which ones are which, 32volts audio and 9volts TV im pretty sure. so how do i diagnose this? because i am wondering if its the power supply, or blown resistors or fuse maybe? thanks!

My Zenith tv has wild colors and double image. what do i do?


Possible that the lamps are out of alignment resulting in poor convergence of the image.
You might have tto use a test pattern to see if this can be corrected or if this is the fault if the convergence section.

Tv wont turn on


You need 2 STK392-110 Convergence ICs and possibly 6 2.2 ohm 2watt resistors. You can get the convergence repair kit for your model from www.tvrepairworld.com the kit contains the ICs, resistors and the CD with instructions. The PT47WX42 convergence kit is the correct one for your model.

HD 1080 Series (WD-55809) - Color convergence issue


I don't know of illustrated instructions but I can provide you with the service manual for your TV. It does have illustrations of disassembly and components as well as schematics. Your set very likely needs new convergence IC chips. This is a common problem with all projection TVs. The repair is not expensive ($60-75 in parts)  but does involve unsoldering and removing the old chips and soldering in new ones. Some times there are some fuses that need to be replaced as well. If you want the manual provide me with an email address.

My 6 year old 65xwx20b tv convergence problem


Good Day,

This is a common problem with this TV, but there is an upgrade to correct the CONVERVGENCE circuit problem.
If you want to repair this concern yourself: Contact: B&D ENTERPRISES,
1-800-458-6053, www.bdent.com and ask for KIT10 for your Hitachi TV.
If you want some else to do the repair for you call an Authorized Service Center.

THE COLORS ARE SIDE BY SIDE AND BOWED


Projection sets have two very common problems outlined below.

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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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 have what I believe is a convergence problem. The red line curves down at the sides on the adjustment screen and when I am viewing TV the picture has a red ghost curving up at the sides of the picture....


Hi, this is a convergence chip failure and it can only be corrected by replacing the entire convergence board in this unit. This Board regulates and collaborates the RGB streams. if there is an apparent malfunction, it will become impossible to correct the issues you are experiencing at this time.

Simply replacing the convergence board or chip set will fix this issue.
