    I posted a few days ago about some substance I found on my CRT Chassis (Sony 1271QM)

    I've since found that the coolant has leaked from the Green tube. The other 2 tubes are full but the green is missing some from the top - approx. 3 mm from the top of the raster.

    Is this leak going to continue and can I repair the tube?

    Gag this is beyond me. Never tried it. Go to AVScience and ask Curt Palme specifically. He or Chuck Williams have best knowledge of Sony 12xx series.

    I'm not aware of a way of recovering this. The seal between the tube and the coolent glass has failed and the fluid will be squeezed out as it heats up. Typically the seals fail when an image is projected too large or too close to the edge of the phospher surface.

    Is your projector ceilling monunted? you mentioned that the corresion was in the chasis which means it must have been table mounted at some stage. (just trying to establish if something has changed.)

    The good news is you can use the PJ provided the coolent doesn't drop too much more. The bad news is. You will have to get a replacement at some stage.

    I asked on the AVS Forum and by all accounts it's repairable. :)

    Apparently the seals can be repaired with Silicone Sealer and I just then need to top it back up with new fluid. I've found somewhere who'll give me some out of a dud tube.

    The projector was originally table mounted I believe but I intend to ceiling mount it once I can get hold of one of those damn Sony mounts :mad:

    Fingers crossed and thanks for the replies.

    It's worth a try I agree.
