Re: projection tv problem lens
As you stated very few companies provide the rubber seals.
The best thing to use is silicon, place it where the seal is. Remove the CRT from the unit, drain the fluid, clean area, replace with Ethylene Glycol. Make sure you let the silicon to set up, about 24 hours.
Good Luck, Day, Big Irish.

This TV is garbage! Finally through mine out in the garbage - replaced the lamp cost from $100-300 - both lamps exploded - replaced optical block twice - lens very distorted - plain old garbage! I will never buy sony products again especially since I paid 4,000 for this tv it was new tech at the time and I was desperate for a tv - sad I am!
First I have to say that the fluid is what keeps the tube cool, if you use the TV without replacing the fluid, the tube will eventually burn out. Now the fluid has to be replaced, I would suggest that you have a qualified TV technician do this. The fix for this problem is to reinstall the seals on the tube refill the coolant, and reinstall the tube. Coolant can be purchased from the manufacture or from a parts supply store.
This is a problem with the AKB circuit. Are you comfortable working with TV circuits? Can you solder? If so, please update this and I'll look up the most likely parts late today and post them for you.
how old is your set?. This TV uses A bulb for its light source...(LCD Projection). If your tv is a few years old, and has over 4000 hours of use on it...your bulb may be on it's way out. The first sign of the bulb getting weak is loss in brightness of picture. Also make sure you vaccum the back of the set regularly, as there are fans to keep the bulb system cool, and if the fans and vents get full of dust, the bulb won't cool as well leading to premature failure.
