My tv had three screen, what do I do to get it off


Sounds like your convergence board went out. This board aligns the Blue image to impose over the Green image and also the Red to again impose over the Green. This will take a TV Technician to replace and to fine tune your TV's image.

Your other model was more than likely a CRT projector where you coulod manually align the Red/Green/Blue guns. The one you have now is more than likely an LCD projector which can't be readily aligned. Sounds like the panel is failing.

The screen seems to have two of the same image, green and red.


Yes.
The fix is to replace the two Convergence IC's( STK392-110's) with STK392-150's. They are located to the right side of the chassis and mounted to large heat sinks. Be also on the look out for some burnt resisters and or discolored resistors that failed becuase of the IC's failing. These would be located just to the left of the heat sinks. If they are burnt or severly discolored, you will need to replace them with the exact valued resistors. In this high current circuit it is a must.
I hope this helps,

Color is mostly yellow and blue with double images


you have lost the convergence IC`s in your set, this really isn`t a diy repair unless you are very proficient in un-soldering and re-soldering components, once replaced there will be an alignment procedure as well that will require the service manual also, if you have more questions feel free to ask away, video-tek

Double image/ out of focus with green and blue seperation


Your tv is crt-based and is out of convergence. In other words, the settings for keeping the Red, Green and Blue images aligned have drifted and must be reset. This is common with CRT projectors and CRT rear projection tvs.

Refer to your owners manual for instructions on re-aligning it.
