Need to check D647 which is a diode sony part number 6-500-567-01 even if it checks good probley need to replace. Also need to check Q 691 part number 2SA933AS-QT which is a transistor may check good but should replace, it crosses to a ecg part number 290A . Also should check D 645 which is the same part as D647 it looks like you cand use a ECG diode part number 552 for theses diodes. If u dont know anything about tv repair u might want to take to a shop for repair. There is high voltage inside your tv that can hurt you, if you are going to try and do this yourself then be sure and unplug the tv from ( AC ) still there is a good chance that there is still high voltage in the set even after you let it sit unpluged for a day or longer.

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.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please let me know if I can be of further assistance.

You have what is commonly known as a shutdown problem. It's an overload in one of the internal circuits. It needs to be looked at by a professional tv reapir person.

Tips for a great answer:

Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen slightly.
