My sony tv keeps switching off within seconds of my hitting the on button and the standby button keeps blinking (approximately 14 times in total - around 10 if you count after the set turns off - this doesn't seem to fit within the blink-diagnostics). Anyone know what might be causing this or how to fix it? Thanks in advance!
Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board

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.
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.

The power supply board is failing. There are twi integrated circuits in the horizontal drive circuitry that have to be replaced. The original integrated circuits are the same type and you will see written on each..."MCZ3001D" and need to be replaced with Sony # 670581001 or the "D" board with those parts on it needs to be replaced. The cost of the entire board is high-about $375.

Hello,For model KV-40XBR800,
Pls check following area.
Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.
And NOTE: 6 blinks also can be Low B+ protection.
Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.
Good Luck
