Well the green gun is whats inside the green picture tube or crt(cathode ray tube).. Irt certainly sounds like you have a problem with the convergence but the only way to tell for sure is put on a full cross hatch pattern like the one thats used for major alighnments such as after a tube is replace. This problem you have is probably the convergence IC and the part dosent unplug or come out easyly as there are no user serviceable parts inside this set. It should be left up to the service station for the manufacturer. Not alot you can do unless your a tech . Sorry Good luck

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

Wavy green lines and offset during convergence calibration


There is whats called a convergence IC that is going bad inside this TV set. There is only one for all three tubes and the IC number is STK 393-11- and can be purchased here http://www.electronic-repair-kits.com/STK393-110.html You will only need to order one. If you are handy and can solder this should correct your problem. One very important thing is, before you reinstall the new convergence IC, make sure you use a good coating of heat sink compound on the back of the new IC. If you do not, the IC will fail within a short time frames. Only if you are good with a soldering gun should you attempt the repair. If you are not, this repair should run you about 300 bucks or so. Also if you are handy, there are seven capacitors that go bad inside a board called the DM board. These will go bad very soon so while your in there these should be changed as well. If you need info on how to change these capacitors, let me know and leave an e-mail and I will send you the pictorial on how this is done. the IC change you will need to find that, but I do have a service manual if you need one also to help you along if you can follow the schematic. Good Luck

Lcd looks a red wave line it look like it's out


Projection sets have two very common problems.

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

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the lance..it's something else..don't know what..do you?


Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html

Red arching lines


is this that you are adjusting called convergence? If so then if it's really bad you can try to reset convergence, if not then the red needs to be aligned up with green first then blue on green. Can you provide a picture of what it looks like?
