Re: tilted tv screen
The complete convergence for the Philips projection sets usually requires a clear plastic overlay which fits over the screen and has many precisely spaced black dots. The remote is then used to enter the service mode and converge all 3 colors onto the dots, and then the settings are stored in an EPROM IC. This should only be done by someone with experience with the Philips sets.

If the tilt is not that bad, I would leave it be. The reason is yes you can straighten the tilt out, but it requires a mechanical alignment to all 3 CRT's then you will have to align the convergence on all 3 as well. Please take a few moments to rate my answer. Thank you.
Yes, you do need to set up the convergence in order to get the picture geometry correct. the antenna and maybe some other settings will need to be restored through the appropriate user interface screens. You will need your owners manual for a guide.
you have convergence menus
Coarse Green Tilt
Coarse Red & Blue Tilt
the TV should have a Crosshatch or convergence signal
green done first to make it level
then blue and red to match the green
be carefull not to change any other setting other than the Tilt; because you can really mess up your convergence
if the menu adjustments dont do this for you:
you have a light box assembly inside the set that has the Red, Green and Blue Guns mounted on it: it can be mis alaigned as a whole causing what you are discribing. Also, you have a mirror that relects the guns onto the back of your screen: less likely but it could be misaligned..
Just be carefull not to touch any of the following:
wires, circuits, circuit boards, heat sinks, and especially the three Big wires that go to the 3 picture tubses... they have high voltage
the heat sinks could also be live .. Just be carefull !
make sure you have really good lighting and room to work and you should be able to fix this without a problem.
no its not true, you can lay them flat to move, it sounds like the convergence is out of whack, download the owners manual and redo the convergence manually for the red and blue, then go back and do the same for the multi point convergence for the red and blue, also if the color looks muted or flat, the projector lenses might need to be cleaned as well as the mirror in side of the unit.... very easy to do, just use caution and DO NOT SPRAY ANY LIQUIDS INSIDE THE UNIT.... spray the cleaning rag outside the unit the wipe off the mirror and lenses....i got this same TV free from craigs list here in pa, put a new mirror in because the original was shattered and re did the convergence and this TV pic is AWSOME.... very crisp and clear...hope this helps you
If evrything lines up when you tilt the set backwards , you may just need to make sure the mirror is tight. The clips may have loosened over the years therefore throwing the aim out of alignment. If the mirror is tight ,then I would suspect a loose connection. You might try having a mirror and try moving some wires with an insulated tool from behind while you look into the mirror to see if it has any affect on the convergence. Could be something as simple as a loose plug. Hope this helps.
