Unfortunately that's an indication of the crt going bad in a Sony.
You can turn the G2 voltage down on the flyback or have a tech rejuvenate the picture tube but either of these are only a temporary fix..
The flyback is the rather large transformer with a red (anode) wire coming from it and attaching to the crt. (looks like a suction cup).
There are two adjustments on the back of the FBT, one is screen (or G2) the other is focus. With the unit on turn the G2 counter clockwise just a little and the picture will get slightly less bright. That should stop the picture from blinking out - or doing so as often. But again, it's only temporary!
Good thing Santa's almost here... :)

Mitsubishi Rear Projection TV Model WS-55311

Rear projection TVs are dinosaurs. Sell it if you can get anybody to buy it and get an HDtv they're pretty cheap now not to mention thinner, lighter and better for your eyes. Imagine the space you'll save if you mount it on the wall and the cost of electricity. Not trying to be a jerk but it's time to move into the 21st century. The picture is waaaaay better.

My sony tv stars blinking 5 times in a row, then the picture goes black for a second comes back then goes black again and it keeps doing it non stop

tv has a blanking picture mute circuit. adjust the screen controls which are located behind the speaker grill in front of set. there will be a access panel to unscrew in center and then you will see a black 4 inch square box with 6 physical knobs. 3 control screen the other 3 controls focus for red, green, blue. turn them down and slowly start turning them up. fixed.

The tv just randomly turns off by itself

Check to see how many times it blinks when turning off and then look for the codes for Sony tv blinks. this will tell you what's wrong. This set is notorious for Shorted tubes.
