For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.
THE TUBE IS REPLACEABLE, HOWEVER YOU MUST VERIFY IT IS BAD FIRST. THERE ARE 3 OTHER PROBLEMS THAT YOU NEED TO ELIMINATE FIRST BEFORE YOU SPEND $250.00 ON A NEW TUBE.
Your blue picture tube is brighter than the other tubes. Try to do a convergence on it. If that doesn't do it, it sounds like you blue picutre tube is getting ready to blow. It is the same principle like a light bulbs. You know how they get bright and in a next few days they blow. That stands true to a picture set.
model number is located on bottom rear cover, your convergence circuit has failed but without model nobody can give you further info, re-post and we`ll try to help, video-tek
After a typical picture tube ages it gets a coating of chemicals
(carbon, phosphor and various metals form heater filaments) on the red,
green or blue electron guns. This degrades any one or all three guns
over time. There is a process to "zap" or rejuvenate the picture tube. A "good" TV repair
shop will have the device to do this. The cost should be between 1 to
2 hours of repair labor. That equates to $75 - $150. The only thing is
that this process does not clean the guns effectively
and they can "cake up" again. Think of it as a coronary cleaning, it
does not mean the "plaque" can build back up. It will, and usually
within 1 to 3 years depending on how old the unit is and how long it is
on per day. The other alternative is replacing the picture tube. 2 - 3
hours of labor plus parts. An average picture tube (after technician's
mark up) costs anywhere from
$100 for 13'" set to thousands. Looking at your model, it's a 31". I
would guess at $400 - $500 just for the picture tube. I like Mitsu's.
A good machine. Right in line with Sony on up. (and better in a number
of occasions I have seen) When the cost of the repair is over 50% of
the cost of the unit, that's when I declare it replaceable at the hospital system where I worked. (Over 900 TVs) You should weigh the price too.
Hope this insight helps - Let me know if it did.

The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?
1 5 oz bottle should be enough for each tube. The small picture is caused by bad opto-couplers on the large signal board. Let me know if you need more info on the couplers and where to get them
