KDL-40XBR3 turns itself off; STANDBY light flashes 9 times

Five times blinks to Sony Bravia is related with an IRK error. It is related to its main digital board. In most cases, the main board might need replacement. It will be best to contact the authorized service center for Sony.

I am experiencing exactly the same problem. TV turns on but within 60 seconds the screen goes black and the red standby light blinks six times. Were you able to resolve this problem on your TV?

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

I finally managed to solve this problem by unplugging everything - scarts - HDD cables - power etc and left it for an hour. When I turned it back on again the problem had sorted itself out.

Replaced circuit board under warranty.

Seek professional serv technician. No listing for 13 fashes only up to 9.

Are you sure about the 13 flashes. Error code only goes to 8 flashes.

This sounds like a power source problem! (faulty transformer) I would pack it up and take it back for a new one!
This is a problem you can not fix yourself unless your a pro!
Please rate my response!

hi have you check the sleep timer on the tv cause it might be on and you need to turn it off

Replace the BU Mount pcb. Sometimes they are called the FB pcb.
