Have sound but no picture at all... not even the channel indicator or only visual using the TV remote. Don't projection tv's have 3 bulbs (blue/green/red)? if one burns out, wouldn;t the other two still work? Any ideas. Bought the TV from Tweeter but their 800 repair service has not bee responsive.

Its definitely not the CRTs. More likely a problem in your deflection circuit Horizontal or vertical. Could be the vertical output as well. your not getting deflection if you don't have any menu or channel indicator.How are your trouble shooting and soldering skills?Let me know if I can help you further.

A brief history: fixya helped me change my bulb (been receiving a "replace bulb" message for awhile until my picture went black). The picture now is snow, not black which seems to me to indicate the bulb...

Since you do have sound but snow for picture is your TV 54J or 54U chassis the PT50DL54J chassis shows 4 tuners also Have you look for Leaky or Bad capacitors if they are puffed up on top they are Bad 2200uf 25v 1000uf 25v Look for bad capacitors on tuner Boards, and I have seen where they are on Power supply board that will affect Picture.

Menu will not display

If the channel and volume visual display was not set up on the menu to display on screen , neither will show up even if either the remote or set front button are used. Make sure that the tv button is selected on the remote to access the menu .If that does not work ,then either the batteries are dead or the remote is dead.If it is you will need a new remote,sadly. Then you can press the m button , select sound and then select "display volume" and check "during adjustment". The channel display settings are found on "features" from the main menu. Hope this helps.
