I get the small screan but no picture in the small screan. The larger portion of the screan is okay. What I do get on the small screan is faded patterns and I am unable to distinguish valid pictures.
Any help would be greatly appreciated.

there may be dust behind the screen & also on the reflecting glass. u will see that upper back portion cover is removable. remove it & see that glass there is glass on inner side of cover. clean it, also clean the screen. u will see there are 3 picture tubes faces on bottom side, clean all of them.
if it does not work then u can increase brightness of tv by increasing "screen" control of tv which is on the lower back portion of tv. this can be done by any tv repair expert only.
a lot of these just have bad solder connections, but its a convergence failure either way. http://www.fixya.com/support/r5001731-convergence_diagnosing_convergence Let me know if I can be of further assistance.
Several possibilities, if you use a set top box to get your signal like a cable box or satellite receiver they will have settings that effect picture size. It could be a high voltage problem inside the TV causing an effect called blooming, if that is it you can usually change brightness and or contrast and see the picture get smaller and larger. I don't recall that set having any customer settings that could give that symptom.
is this a new tv what ever the problem try to see what settings you are on like factory or custom
okay if on factory put on custom and try to adjust to your likings what i like to do is take the color settings all the way down try to make a black and white tv like the old days then start bringing
the color up see what happens okay good luck
I have Mitsubishi TV CS-31303. It has transient issues. At turn on, it shows horizontal fringes for some time along with picture, then single horizontal line only and then after some time finges at the 1/3rd bottom and then clear full picture. After some more time the clear picture turns into horizontal fringes at the bottom 3rd of the picture and picture rolls and then again the picture is very clear. Some one said that there is an issue in the signal PCB. Where is it and what componets are at fault. I do have service manual which shows circuit diagrams.
