I have a Curtis Mathes 32" model cm32020s. The picture is coming in as green only. I have adjusted the tint and color settings however the green color remains. How can I fix this problem?

The contrast setting controls the relation between the light and black areas of the screen. If the light areas are too bright and are losing details, press the CVOL button; if the picture is gray and lacks contrast, press the VOLB button

The brightness setting controls the overall amount of light in the picture. If the picture is too bright, press the CVOL button; if the picture is too dark, press the VOL B button

The color setting controls the intensity of color.

No. It can't.

They should be able to help you with the tint on your television not look right. A member of their site should be able to help you with the menu and other problems you might be having, and they do it for free :)

This fault is called one color predominant screen. The cause might be to its video output card itself. There will be some loose solder terminals around the Green video output transistor. Check this card for any loose solder terminals. Just re-solder all the suspected solder terminals by applying a little more solder, without making any solder bridge short in between adjacent solder terminals. This card can be located at the neck of the picture tube [a rectangular board], will be directly plugged on to the back of the picture tube.

I would open it first and look, a lot of those had both the screen and drive controls on the PCB at the end of the picture tube, at least look there first.

You are dead on in looking for the screen controls, if you find one it should only be a tiny adjustment due to age and the Crt changing a bit.

A explanation that may tell you what is happening:

Some of their sets had this issue. The picture tube has a metal screen inside directly behind the stripes that make up the phosphor coating on the inside of the picture tube.

It is called a shadow mask. It has perforations that line up with all the stripes on the screen (look close--red-green-blue stripes all outlined in black--tiny).

What is wrong is not fixable even if the tube is replaced----the metal used in these sets for the mask contains iron which causes it to expand in areas with real bright scene changes--

No need to remove question as I saw it and answer questions for most TV area problems.

I actually ten years ago worked for Circuit City--saw at least 5 sets (all larger Toshiba sets) with this issue. On seeing first one called our support staff and someone explained to me the issue---that set was under extended warranty and since the customer was angry the set was "exchanged" for a brand new set and the old one was disposed of.

Code 5 is "AKB error". AKB, or auto kine bias, is a cicuit that monitors the three color guns of the picture tube (red, green and blue) and tries to adjust them for proper color balance. If it can't, the picture is blanked (usually) and the timer/standby light blinks 5 times. When the color drives aren't balanced, you see a color tint in the picture like you're describing.

There might be a problem in the AKB circuit, or the picture tube may just be old enough that the AKB circuit has run out of adjustment range. If the tube is at fault, you should consider replacing the set. A new tube will cost nearly as much as a new 32-inch LCD TV, and you'll need to pay someone to install it and set it up. There are special tools required to perform the convergence which gets the color guns aligned with the face of the tube so they hit the right colors.

If you'd like to try tinkering with the service menu adjustments, this site explains how to access the menu and gives a list of settings.

sounds like you may need a new tube

My picture would go out after several minutes but I still had sound. I took the rear cover off and blew all the dust off with compresed air.I did this for a few times over several days nothing happened.I also took off the rear circuit board that attaches to the tube with a round pin socket and blew that with compressed air and put it back on. The TV has now worked for two days without the picture going out. It worked!!!!!!!!!!!!!!
