Hi,
1. When I turn on my T.V. after it hasn't been on for a while the screen starts shaking. When that happens the image moves really quickly up and down the screen. Then after the tv has been on for a while it stops. But after about an hour being off when you turn it on it does the same thing.
2. The color is messed up sometimes. Sometimes when I am watching the tv something that is supposed to be blue turns green.
Please let me know if you know what is going on.
Thanks

After 11 years???? OMG This set is a tired pup and should be put to reast. My experience with older sets and your complains are all capacitor problems and is only gonna get worse as the first time around repair will take several capacitors to repair. This set has no user serviceable parts inside so you should not attempt a repair suchj as this on your own.. This repair if you decide to go through the first time will be About 300 to 600 bucks the first time and cost will continue to raise till the sets put to sleep. Good luck

I Can Assure You That This Problem Is Associated With 2 Capicators On The Power Supply Board.
SOURCE: shaking screen
Check the 9v regulator Ic2p01 on the signal board for correct regulation 8.9 to 9.1 volts. If voltage at the output is under 8.9v, replace the regulator Ic. Always replace C2p05 100 Ufd 16 V on this set and that should take care of the shakes but you may want the tech to go ahead and ESR some of the other troublesome caps throughout the Tv. He'll know what you mean. Many of the 100mf caps replace automatically. Several others will have a questionable ESR and should be replaced. Caps are inexpensive, but probing with an ESR meter is somewhat labor intensive so you miht discuss with the tech just how far you want him to go testing for bad caps.
A Mits is a great Tv and this repair is clearly worth it..

I had the same problem. I deducted that if my TV worked fine for an hour or so and then the colors became bad (green, people's faces purple...), it must be a overheating problem. Simple logic, right? So, I picked up a few tools and a small vaccum and went to work.
I went first for the main source of heat: The lamp. Just a few screws, and I removed it. The lamp cage has a fine screen to prevent the dust to cover the lamp. Mine was covered with dust! And the fan behind the lamp was also covered with dust! Bingo!!! That's my problem! I cleaned everything and vaccumed all the air vents on the the back of the TV. I put the lamp back and checked that the fan was working. The TV works like new since!
Before you are out of a TV for days and spend an arm and a leg for a "Technician" to fix it (replacing expensive parts that didn't need to be replaced in the first place), try what I described above first. It's very simple and it takes only 15 minutes.
Since my TV is 2 1/2 years old, I purchased a replacement lamp. I know that one of these days it will burn out. I'll be ready and my TV will be working again in 15 minutes!
Since my problem was solved, I didn't go to the next step. There must be one or two other cooling fans inside the TV, but they must be working...
Good luck,
