How do you remove the front screen on the projection TV

When I first bought my SONY KP-51HW40 they had to take the top off to get it into our basement. Now I am trying to move it out of my basement I can only get the back mirror off but the front screen is still mysteriously attached. I can disconnect the wires from the electronic board but can't figure out how to remove the screen there are no visible screws to unscrew?? any thoughts

sounds like you have a bad tube you can attepmt a temporary fix for this problem but is kinda hazardous and does'nt always do any good . but you can remove the front of the tv where the speakers areand tap on the base of the tubes lightly to see if you can get some of the carbon build up loose from inside the tube. also try adjusting the screen voltage for what ever color you see the lines for sometimes turning down the screen voltage can help

Screen shakes / jumps vertically on my Sony KP-51HW40

The jitter is called a vertical sync problem. The problem is on the "A" board. It can be replaced or rebuilt but will be quite expensive to service.

Open up the front of the set by removing the speaker screen and the black piece of particle board. on the bottom right you will see 4 knobs. Turn those knobs slowly till the arcs go away. The 3 knobs on the bottom are for color. the 3 on top are for the focus.

Yes you have bad green and red crt but with an adjustment you can still use it. remove the front panel and you'll see the focus pack (it;s a black piece with 6 rotating knobs on it. Adjust clock otherwise the red and green screen (the bottom line knobs) till the lines has gone. The better way to check it is to adujt in video input with no signal, just black screen.
