Well it all started off with a bunch of red lines thru out the screen (alot on dark picture) then the picture went out. i have had no other problems but this. really can't afford to purchase a new set right now so any help would be greatly appreciated. thanks!!!!!!!
I have the same problem. I had someone come out and take a look at it they told me it was a DM module or signal board. Unfortunately Mitsubishi does not make the part anymore!! I'm very upset. I'm not saying this is your problem, but look at it as a possibility...

Your blue picture tube is failing. Invest in a new TV. "If" you can find a new set of tubes(you have to replace all 3 red blue and green) they are around $800-1000. Not cost effective. Run the TV into the ground if you want to wait but do not invest any repair money in my opinion.
Even if a convergence problem exists you should still have a picture, a bad one but a picture----call the menu up with the Mitsubishi remote and select convergence and then advanced---a grid of lines will appear in green---got dramatic red and blue showing and you have a convergence issue.
Do that first----presuming no hookup is ok (try a dvd player) the set does have the OPTION menu(can tell you how to get there) that is based on a 4 digit number code--may have that for this model or not).
It will not correct any convergence problems but will do a hard reset of the set back to factory original.
Let me know what you find---it sounds like 2 problems exist.
Yes, either some resistor has changed and it's pulling down the blue and green or depending on how much red it could be a short on the red line. Also you can open back of set and try this. Each CRT's have a Focus Block with Screen control. Maybe you can turn down red and align up with blue and green. The professional way of doing color is to get a good grey scale, meaning black and white picture. THis is turning down you color on set to zero and looking and adjusting to black and white as good as possible. You can try this but if there is a serious problem it may not help. The problem may have to be resolved first. Be very careful in touching anything while set is on, unfortunatly you have to have the set on to properly adjust. but you can use something plastic or rubber end screw drivers
