Hi,
I have a Sony kdl-37u4000 which has suddenly died. The green power light comes on for a few seconds, then a very quiet 'powering up' sound which stops almost instantly and the red timer led starts to flash four times.
I've tried to find the fault codes online but a lot of stuff on the web seems to refer to codes for Sony CRTs.
I've taken the back off and there are no obvious signs of damage / overheating etc, even under the cover on the inverter board.
Any advice on what the four flashes mean and how to fix would be much appreciated.
Thanks
Google
