Re: blown fuse?

Your problem is that the power supply of the tv went out and it wasn't beacuse of a bad fuse. need to take it to a tech service to check it.

I turned the TV on, a mild 'pop' sound, and it immediatly shut off. Now it won't power on at all. Is it worth fixing? Its 11 years old (July 1998). Thanks for any advice!!

you may have just blown a fuse. check and replace with same size and type. if you smell burning, you fried something, and it may not be worth replaing on a 11 yr old tv.

Sony rear projection screen is red then tv shuts off

Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.

Sony Trinitron WEGA won't turn on

6 blink error is either a power supply (g2 board) or a blown thermal fuse. if it came back on, its not the thermal fuse so you would need a new g2 board. if it blinks 5 times, you need a new ballast (lamp driver)

No , if fuse was blown you would not get the popping. How old is unit ? It sounds like your high volt splitter. common problem with rca. repair should not cost more than 250.00. you will want to have chassis number  and manu date for help

Dead tv

Sounds like a power supply problem. I am sure that the pop is the fuse blown. If the fuse is blown, this means that there is a short somewhere. Rear projection TV are like LCD projectors. And all of them use Switch mode power supply. If you are lucky, there is a chance that a protection device (like a varistor) is sorted. This means that removing this, even without replacing will bring your TV to life, however... Most probably the power supply is defective.
