    when i turn it on it is fine for about 1 minute. Then the scree turns red with dark red horizontal lines and it turns itself off.

Tv turns on red and then turns off.


It sounds like you have a shorted red CRT and it caused phoshor burns on all three CRTs because the blanking circuit could not blank the picture fast enough at time of shut down.
It can be repaired but all three CRTs must be replaced. Cost of doing this is too much for the age of the set. I would invest instead in a LCD projection or LCD flat panel.
Hope this helps,
