There are fuses in most TV's... and in some cases, it's nothing but the fuse. BUT, the fuses are there to protect the circuits... so unless you know that there is nothing wrong with the TV, you shouldn't simply replace the fuse and plug it back in. However, if the TV is an older TV and it's either fix it by replacing the fuse or get rid of the TV... then I'd certainly take out the screws and check the fuses in the TV. But many times the fuse blows to protect it when something else fails... so if you find a blown fuse, look around for other signs.

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.

Picture color is distorted.


Try turning off power and let set cool completely. Then turn back on. Letting it cool complety re-arms the autmatic degaussing circuit. It may take several cycles to completly clear it up.

Tv doesn't turn on.


Does this have a replacable lamp? If so it will do exactly this. If it does it's probably fried.

That generally means that the CRT is weak and is putting out low emmisions. This is confirmed by the fact that the color quality is not that great when you can see a picture IE: not enough red, green or blue. This is very common when these CRT's age.

Power on no picture no sound


the 2 bilnks is a fault code for a (b+ overcurrent), you could have a bad horizontal output check q506 or q505, varies by modle. I have also run into a bad color amp ic1751. use a multimeter to test the h. o/p transistor, as for the ic, easier to replace than test.
