Check the filter capacitor to the supply to video output card. You can locate this capacitor at the CRT base card to your Sony Trinitron. Replace this electrolytic capacitor.

U have a soldering iron,desoldering pump or a roll of desoldering braids,a roll of solders?Can u do basic soldering and uderstand basic electronic?FBT- the flyback transformer,the big black block of a plastic with a red wire with a cap hook to a CRT-tv picture tube.Near the big block of a plastic with a red wire with a cap hook to a CRT picture tube.Inside to the right of the FBT,there are 2 power supply ICS,those 2 ICS are dead.Replaced these 2 power supply ICS near the FBT,will solved this tv LED power light indication blinking and will have stable tv power again,and tv will work.

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.

It sounds like it might bbe a fuse. Take the back off and check the fuse for open,(blowed). Replace it with the same amps. ...Hope this helps...

do you have any audio? if you do the it's usually a fuse for the video circuit. if no sound no picture, then main fuse power supply out

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.

Sony Trinitron TV. Worked well last evening. Now picture won't go on. When power is turned on, standby/timer red light flashes, but picture or sound does not work.

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.

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.
