Hi Bronco5

The set is shutting down into protection mode because it has a problem that will need to be repaired. It is likely that a power supply has a fault, or an associated power section of the set has developed a fault problem. Because of the complex nature of Sony power supplies and isolating the fault, If you are not an experienced electronics technician familiar with these circuits, I suggest taking it to an authorised Sony service center to get a quote on repair. Sorry this is not perhaps the solution that you were hoping for, but is the best advice in this case. Feel free to ask any questions you may have, and I will try to answer them for you. Good Luck

Seems to be a problem with the power board. Most likely a failing flyback autotransformer. You will most likely need to replace this part.

It is best to call a TV technician for this kind of job, especially if you are not experienced in this. There are voltages inside that can kill.

However, if you think you can manage a DIY, please try THIS site. They have spares and provide online chat assistance and you will have unlimited professional support so you can diagnose and repair your television yourself.

Should you have any further queries, please post back and I will be more than happy to assist you further.

Hope that helps, and good luck!

    Try changing the Scart cable. It seems that may be defective. If that does not work, it could be that the Scart jack on your TV may have some bent pins. Try using a needle nose pliers to gently bend the bent pins back in shape.
    You can also try cleaning the contacts with a bit of cotton dabbed in isoporpyl alcohol.

    If you are still having issues, you will most likely have to get the Scart jacks replaced. Or you can try connecting the cables using the RCA connectors.

If it goes in secure mode immedately after power up then it is probably a problem with the power unit, in need of replacement.
If the power led is blinking a certain number of times it can be also a problem with control board.
Tell us if you have led blinking or any additional symptom.

Hello 0279737,

This problem is caused by a shorted Horizontal Output Transistor. I would suggest that you have this TV checked by a qualified TV technician. This type of problem requires dealing with dangerous voltages, and repair should only be attempted by a trained technician.

I hope this helps

Thank you,

This may be a power supply, and or a high voltage, or a scan ampplifier failure. The set would have to be properly trouble shooted by an experienced TV tech to determine the exact failure. This is not something you can fix yourself at home.
