For the past year, more and more blue and green dots have been appearing across the screen. They're about 2 1/2 inches in diameter. I was wondering if there is a part I can buy to repair the problem? Any help is appreciated.
In most cases, this might be a panel problem.

it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected
and if all seems to be ok, the DG board will need to be replaced.
If you dont have any repair skills I would recommend you to take you TV to a repair shop since this is complex repair

Unfortunately your light engine(also know as optic block) may need to be replaced. If your tv is out of warranty, it will probably cost around $1000 to fix. There is a slim possibility that the optics lens could have dust on it and a tech could clean it for much less than that. This is a very common problem in any dlp tv and they are all expensive to fix. I've replaced several of them at our shop, but about half of the customers won't have the tv fixed and will get a new one. Good luck!

I would say the matrix of the screen has a shorted transistor. you can see if it's a thermal problem by shutting it off for a while, and then after it's cooled down. power it up... see if goes away, then comes back...
Hopefully its still in Warranty... it's not a simple method of changing a single part. as they dont make them like that any more. some displays are all "Integrated" with driver xistors part of the assembly...
If you were having a thermal problem, I'd would buy a can of Freeze spray that the techs use to instantly cool a part down for testing... then you would have to spray around the back of the unit to cool it down. hoping it's under warranty tho... maybe you'll be lucky and settle for putting a fan behind the screen if it's out of warranty...

Have you tried lifting the ground on the TV? That set has a grounded (3-prong) plug and sometimes sccrolling lines can be caused by a ground loop in your power lines.Are the green and purple lines very short, like just a few rows of pixels tall, or multiple inches, like 3 - 8 tall?
