Have a shop look at it, there is a power relay that either is causing this or something right around it is, seen this about five times over the last ten years in Hitachi sets. I had one customer who had it connected to a wall switch and from time to time had to unpower it several times but once on it was fine.....
If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.
If i remember correctly ten blinks means a high voltage error. The only thing you could try is unplugging the power cord then plug it back in and try turning on the tv. If it still won't turn on try unplugging the power cord for five hours or longer and try again. If it still won't turn on it would be best to find a local repair shop that works on sony tv's and have them repair it for you.
Hit the front of the tv near the blinking light... give it a good rap or two. See if this helps. Helped mine. I had the same problem and the tech who came out to the house told me that it would work and it did! I could hardly believe it but it worked.
The DM power supply board,probobally have those dying leakages gases about to be dead parts call capacitors.U have tools and know basic soldering?Tries website like Tvrepairworld.com to buy a capacitors kit,to replaced those dying capacitors belong in the DM power supply board.
Pull the three connectors to the yokes on the convergence board. If the set powers up, it's a good chance the STK392-110's need to be replaced. I fixed one today, and it has been running for 6 hours now.
You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!
