Picture flutters After warm up the picture starts to flutter or flicker, also colors blead

This sounds like one of the 9 volt regulators on the small signal board is going bad, supplying less than 8 volts. I have seen this is several of those sets. The IC needs to be replaced and if you do not have experience in servicing projection TV's then I suggest letting a qualified tech handle it for you.

SOURCE: horrizontal fluttering when warmed up.

1. HORIZONTAL PULLING AND TEARING, MAY ALSO HAVE VERTICAL ROLLING OR VERTICAL BLANKING BAR LOCKING IN THE MIDDLE OF THE PICTURE. CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB. 2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 (9-VOLT REGULATOR) ON THE SIGNAL PCB

The same is true for rear projection. There may be an adjustment for vertical hold in a hole in the back of the cabinet.

Good Day, monarchdr272;
Sounds like you may have a bad comb filter. Yes things can be repaired. Good Luck, big IRISH.

In case there is a loose connection and the convergence board is not damaged. This is what I did and worked out "perfect".
My Mitsubishi HDTV Medallion 1080 has been with us for about 7 years.
The TV started showing distortioned colors and images and even when I used the convergence options from the main menu, it would not show clear images until it would be working for around an hour or if we would hit it until the image would fix. It got worst over the time at a point that it would require 2-3 hours working and several punches and kicks.
No doubt dust has done it's job, well, a vacum with a brush end can help resolve the problem.
1. Make sure the TV is off and disconnected from power.
2. Remove the rear cover at the back (it is clear wood colored and is at the lower part of the cabinet)
3. Using a vacum with a brush end, vacum all the dust that you will find. Be cautious not to hit the components and do not or apply preassure while doing the work
4. On the left side, you will see a card over a mother board, make sure to vacum it well and that it is well inserted in the slot (I did apply some preassure to make sure it was fully inserted)
It took me around 15 minutes and my tv is working like NEW.
While you are removing the dust with the vacum, you may want to vacum the 3 lenses as well, again, using the vacum, no need to clean them with a cloth. I saw a thick layer of dust over them and could remove it easily with the vacum.
Hope this will work for you.
