SOURCE: Proscan PS50700 Convergence Problem

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Lamp Failure, Ballast, or color wheel?


The ballast board for sure. If the color doesn't come back, try cleaning all the lens elements in the box in front of the lamp. If that still doesn't restore the color correctly, then look at the color wheel.

My tv also has a green tint..


Is the T.V old, or second hand? Or does the picture look dimmer then you think it should be? If so then it could be that the lamp in the projector is coming to the end if its life. The lamps in projector tend to make the image on screen a greenish colour along with a dimmer look once it needs changing. It dosent just pack in though, it will stay like that for a while, but wont get any better. There could be a way of seeing how many hours the lamp has got left before being replaced on the T.Vs menu screen?

Loose hinge,no picture but sounds otherwise OK


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

I had the same problem which was caused by a bad solder connection on my Green CRT driver board. The fix isn't too difficult if you've had some soldering experience.

1) Determine which CRT is going out (Reg, Green, or Blue). Looking at your convergence adjustment screen will help.
2) Unplug TV
3) Remove the front panel
4) Locate the driver board attached to bottom of the bad CRT.
5) Locate the two large heatsinks on the driver board, each has a transistor attached to it.
6) Touch-up the three solder connections on each transistor. Adding some new solder helps.
