No image in blue gun assembly

I have an Akai PT5598HD TV that i received from my mom after her plasma upgrade, in the course of moving it, I noticed there was no blue tones in the display, i removed the back, the blue gun appears to be working, but if you look into the projector, there is no image, its very visible on the red and green assembly, any help would be apreciated, and im interested in fixing it if its not too costly, i was hoping it might be a loose connection. but havent found one yet, thanks in advance!

The fluid in the bule gun is cloudy therefor the image you need to replace the fluid (coolant) inside the gun. the fluid is toxic (eytholene glycol). so have a tech do this for you. the repair may cost $ 325.00 or so.

Akai rear projection tv...picture is not deformed....however there are images (Ghost image) in separated colors...like 3d


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 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

Change CRT coolant in AKAI Pt5598HD


The CRTs in modern TVs do not hold a charge because the HV circuit shunts it to ground whenever you power down the TV. You can clean the lens of the CRTs but you can't change the coolant or should you even try. You'll notice that its sealed from the factory. If you suspect a problem with the coolant or that it has dried up or leaked out, you must replace that CRT.

HD image has lost sharpness


You will need to replace the convergance IC's if the colors are no longer lined up and they won't line up using the tv's controls. Also, if the crt lenses have a lot of dust on them removing that will help the sharpness and brightness of the picture. Don't use canned air. Get a crt lens cloth.

Picture moved up and to the right


I know this is an old post, but it was never replied to and I just joined the site. Does the image only show the shift when on the DVD input? It is possible that the DVD player is the one shifting the image and not the TV. Try another device on that input and see if it goes away. Kenneth
