My Sony TV KV-27V40 just stopped displaying a picture and the standby/timer light is repeatedly blinking 5 times. Any thoughts?
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.

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

Please let me know if I can be of further assistance.

The most common failures are the flyback transformer assembly and sometimes some of its support components, and or there is the possibility of a short in the CRT electron gun. In either case, the power supply is going in to protect mode, and the uPC is sending this flashing error code to the front LED.
I have no idea if the flyback transformer assembly is still available, but I am very sure the CRT is no longer available. In any case you will find the cost of servicing your set to be expensive for its age. The last time I checked, the cost of the CRT exceeded the replacement cost of the set.
