Cannot read directions

Check and replace the picture tube connecting socket at the base card circuit board, directly plugged on to the neck of the picture tube.

Some of your electronics parts were worn out. Like capacitors may have leaks that need to be replace
as use stated that the word focus were very clear it means that your tube is still okay. or you adjust the focus knob on the compartment. To tune in the 3 colors.

when its hard to read words its usually the sharpness which make the t.v.'s look either blurry or sharp or right in between. you can fix this by adjusting it thru your tv's menu either on the tv or your remote, look under the picture tab in the menu and there should be a sharpness adjuster there. adjust as needed

if you are viewing from a projection tv, chances are you have to go thru the menu of the tv to 'picture tuning'. here it gives you different things that could be fixed. one to look for is 'lamp alignment'. It should show all the colors and lines with directions to bring them into focus. This should fix the blurriness and 3-d red/green/white separations. hope this helps you!

You have loose solder connections on the convergence amps.This is a common problem caused by heat within the unit.If you can solder you can fix it.

sounds like a convergence repair is needed that is what happend to me! and the cost is pretty high $300-$400 unless you can do it your self

The convergence integrated circuits have failed and most likely the 2 5A fuses have opened as well. I would find a local Mitsubishi service shop.

This sounds like you have the contrast setting too high, go to your menu and find the contrast settings, and adjust to your requirement. As for the words being blurry, this could be because your tv is HD ready, and unless you view a High Definition channel then the picture will be a liitle blurred.
Hope this is of some help?

you can try to clean the mirror and lenses. or try to adjust the focus for each CRT(picture tube). also could be a convergence alignment issue. check the main menu for convergence alignment feature.
