Good Day, klynn69;
Even though you did not ask a question, I assume you want to know what's wrong. It sounds like the TV has experienced a Convergence Circuit Failure. If you are really handy replace Conv output Amp IC's AND make sure all pico fuses are ok, all jumpers have secure connections OR call for service to An Authorized Service Center and have them come out and give an estimate B4 repair. AVG cost $550.00. Good Luck, big IRISH.

I thought i might need a lamp for my mitsubishi tv--model VS 60607 when my tv is fuzzy when turned on.should i simply replace the lamp or is there something else i should try? thank you!


This TV is a rear projection television and does not have a lamp. It has three CRT color guns (Red, Blue, and Green). You have a convergence issue (the red, blue and green color guns aren't aligned properly) and it doesn't sound like a very big one. You should be able to adjust this through the CONVERGENCE Menu in ADVANCED SETTINGS.
More details can be found in your manual, here. The model number isn't exactly the same but I'm sure the process is identical or really close. The other option would be a bad IC (integrated circuit) for the convergence control. This is unlikely unless your picture looks something like this: captainhawk1_15.jpg

Double images purple and green. try to convergence lines are lined up but there is a wiggly green vertical that won't move.


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

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 projection 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Service convergence alignment procedure


Most non-LCD and plasma TVs have to be manually adjusted with special tools that are used to adjust the internal comparator circuits that align your image. It could be a cheap repair job at a shop.

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.

Projection red is above other colors


Look in your menu for something called "horizontal static convergence" or just "convergence". Adjusting this will align all three tubes electronically. If physical adjustment is needed, then you have to do this manually inside the Tv. keever

Picture Problem


it's very easy to fix convergence manually from the menu, unless it's really really off. there is a button on the front that is an auto focus, that should be used first, then try to manually dial it in. it should be very close after the autofocus (called touchfocus) I got mine for $400 used, and it's great!
