Just a copy from Sony:
5X Blink - TCON & HFR Failure
The 5X blink protection mode indicates a communications error between
the TCON/HFR board and the MT5388 microprocessor on the A-Board. First
replace the TCON/HFR Board if the 5X protection mode blink pattern
occurs. If the TCON/HFR Board does not repair the problem then replace
the A-Board.

This can indicate a problem with the high voltage circuits. Since this is a new set, it should still be under warranty. DO NOT open up the unit as that will void the warranty. Return the set or request warranty service. Note the 8 blinks when you request service as that should allow them to bring the correct replacement parts.
Keep us posted.

Hello,
Unfortunately, this is a failure of the balancer board for the backlight. The unfortunate part is that the balancer is not available by itself anymore, and the whole panel must be replaced, as Sony only has the balancers attached to new panels. You can contact Sony directly to ask for assistance, and it usually helps.
Hope this helps you...

Hello,
There is some confusion on the model (KDL-40W500 vs. KDL-40V2500), so I will direct this toward the 40V2500.
On the KDL-40V2500, an 8X blink means the scan processer has gone bad, and the BU board needs to be replaced. If the problem is intermittent, the the AU board might be the problem, but if it all the time, bank on the BU.
A competent repair shop should be able to help you, or you can try calling Sony directly for assitance.
Hope this helps you...

Hi,
There is a power fault with one of the PCB's inside, contact Sony if you are still in warranty, if not contact a Sony service center as it will need an engineer to open it up to repair it.
Thanks
B+ over voltage protection (OVP), unit goes to the standby mode then
displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
Have you set the output voltage correctly?
