my tv powers up for about 1 minute and then shuts off what could be the problem,

No solution for you...but I have the same problem. I also had the green blob problem which sony fixed earlier this year. It happens on an intermittent basis. Screen goes off, standby light blinks green, then comes back on. Its off for maybe 1-2 min.

It sounds like to me you have a bad Optical Block. It is a expensive repair and you may want to call Sony at 1800-222-SONY and see if the would assist you in repairs. Due to the age of it, they would probably only cover a partial amount of the repair.
Hope this helps,

it sounds like the projection unit went out. if it is still under waranty then i would take back and get it fixed for free. if anything i would contact sony and tell them what is wrong with the tv.

does your power light blink red 3 times?

posible solution is adjust the screen to low.also check the trimer if it is working.check the resistor in the heater line...weng

Sony has a code for those blinks indicating the problem area. Count the blonks till the pause then google Sony blink codes for the area to fix.

Any speakers too close to set?
