I think you are right about the seal issue - check there is no play in the door - most likely causes of it being loose would be a loose latch or worn hinge guides / bent hinge pins. Replace or tighten is hard to say from the info i could find, my guess is it will be much easier to tighten it than to find the spares, although many xg-as are advertised on e-bay "for spares".
One way to test for sure is to put in new film, then tape the door shut as solidly as you can, and tape around the edges with black PVC electrical tape - see if this helps, if not, there may be a problem in the optics, possibly not worth fixing.
There could feasibly be a problem with the shutter sticking slightly, or one of the plates of the aperture could be bent away from its neighbour. Have a look, be gentle.
Only other thing I can think of is the film itself - was it good, new film you had the problem with? old film could feasibly show those symptoms, although unlikely,
Hope this helps, please ask again if you need more info :)

You have a thin horizontal line in the center of the TV. You, in this case have vertical IC that has bad grounds. Resolder the vertical IC pins and check the capacitors in the immediate area and replace these caps as necessary. If you still have a horizontal line, you will have to replace the vertical IC. Find a TV tech or someone with electronic experience to do this for you. Should be reasonable to fix. Thanks for asking and Good Luck!
Do you have a thin line in the middle of the screen running left to right and no picture above or below?
If so read below
This is an easy repair if you've ever soldered or it would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.let me know if this helped. -VOTE
Sounds like a resistor in the convergence circuits or covergence amp ICs them selves. Usually the ICs will distort the picture. My guess would be the flame proof resistors near the ICs 1 or 2 may be oen. Let me know if you need anything further.
Hi Shailendrar , your problem sounds like vertical collapse , the whole picture has collapsed into a thin , very bright centre line ? maybe the result of dry solder joints , does banging on the side of the tv temporarily fix ? if so , the circuit board requires inspection for bad solder joints . Alternately the vertical chip/transistor may be blown , replace as required. Cheers T
