My mitsubishi vs 6047 has been in unheated storage for about 4 years. now picture is very blury. when words are on screen large letters are legible with small white horizontal lines dancing side to side....

Does the picture look like this?

If so I believe your CRT liquid coolant has gone bad and needs replaced.
How to diagnose bad CRT Coolant:

Note: This problem will only affect the GREEN and BLUE picture tubes. The RED CRT is never affected, because the wavelength of the red light does not promote this algae growth
General Symptoms: Washed out, blurry picture, red portions mostly OK, GREEN images have halos, BLUE portions of images may have halos or be missing entirely.Turn the color level control all of the way down and remove the screen and/or the cabinet that contains the mirror. (different for different models) Do not turn the set off or the color level control will reset to preset levels. Look directly into the picture tube lens while the set is on. First look at the RED CRT. Observe the scan lines in the picture. These same lines should also be present in the green and blue picture tubes.
After looking at the RED CRT for comparison, look into the GREEN or BLUE CRTs. If it is contaminated, it will look like there is a layer of film that you have to look thru to see the picture. There may also be swirls and other various contaminates forming. If it is not as clear and sharp as the RED CRT, it is contaminated, and you should change the coolant fluid. IF you wish to tackle this I will supply more information and instructions. This task is medium to hard for non trained people.
Let me know if you wish to get the instructions on changing the fluid.

Mitsubishi VS-60609 60 in. I get sound but no picture. Just a red, green and blue lines in the middle of screen. Looks like a hour glass shape.

That sounds like a bad vertical circuit. Do you know how to use a meter and solder? If so we can troubleshoot otherwise you will need to call a repairman. A good repairman should run you $300-$500 to repair this. Let me know what you would like to do!

No picture

Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at

Since the problem corrected itself initially, it may just be poor solder connections. Try resoldering the pins on the convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If resoldering does not resolve the problem, replace the ICs.

Picture turns red and blue color after television has warmed up

sounds like u are losing green? is that right. could be loose connections somewhere because it works at start up then fails when it heats up. Look in the yellow pages for a mitz auth servicer or call mitsubishi for one near u.

This symptom seems to be a vertical Sweep fault cause what happens is theres a protection circuit in this set that activates when it sees theres no verticle sweep, it shuts off the picture on the set so that the tubes dont get lines burnt in the middle and become damaged. If you know your way around a TV set then you could locate the vertical output IC and resolder all its pins first as well as anything else in that circuit that looks like a cold solder connection. Then i9f it still does the same thing I would just replace the verticle output IC as well as the B+ supply capacitor off the flyback xformer for the sweep dirived power supply. Now if your not knowlegeable about these HI VOLTAGE circuits my advice would be do not attempt the repair yourself as you could get hurt and /or cause more problems with the set as there are no tubes in this set to test except the picture tubes. Contact Mits. at this #800-332-2119 or look in your owners manual for a contact #. Good Luck.
