Tv keeps turning itself off and the white in the picture looks alittle off.

To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.

On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.

Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.

Faded and out of focus picture

Your TV has a burnt CRT base socket. Replace that, it is not a tough job, but make sure that you get the exact same type of base socket.

Click click repeatedly faded then red blinking light

Go to the video menu and turn the color control to minimum. Determine if you have a black & white picture or is it green & white. If the picture is greenish, you have a problem in the screen circuit or possibly a bad picture tube. If the black & white is ok then I would suspect a problem in the chroma circuit such as a bad video jungle IC or a crystal. However, because your set had a red blinking issue prior to your existing condition I would lean towards the picture tube as the source or your troubles. You can try a simple test to determine if you have an intermittant short . Take the back off the set, and with the insulated end of your screw driver, very very lightly tap on the neck of the picture tube near the socket. If you see green flashes or hear loud snaps in conjunction with your taps or the green tint goes away, chances are the tube is the cause. If so, you might try installing an isolation transformer on the picture tube. Good luck
