Sony trinitron kv 32s66 picture goes dark - Sony KV-32S66 32" TV

SOURCE: blinking picture

TV Repairman came out today to look at my Sony KV-36XBR250 today with the exact same problem - he was able to adjust the settings through the service menu, but said it was a temporary fix only.

The picture tube is going and the Sony circuitry has a "video mute" that it uses when it senses the tube is not warmed up enough. The degraded state of the tube causes the blinking on and off as the signal from the tube wavers.

He ballpark estimated the tube replacement cost well above the price for replacing the set with a 37" LCD, so it's going to the dump...

the picture tube is gone.
i repaired 150 sony xbr and kv series with that problem.sony has a single gun not three and has a great pix,but burn out faster.
there is a main screen control that you can adjust ,but the tube is gone.
on the back of the crt there is 3 gun drives r g b .
turn the color all the way down so it is black and white.
if there is a green ore purple tint,one gun is out of balance.
ajdusting the r g b controls so that black and white is normal is what you want to do.
the crt board has the screen bias voltage 800volts on it so be very careful and use an insulated screwdriver to adjust the drive controls.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.
