Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

SOURCE: tv bravia kdl 40v3000 problem turning on

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...

SOURCE: MY SONY KDL-40S4100 IS ON STAND BY AND THE RED

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Where possible, please refer customer to Sony Website -(or ) and search for relevant model to download correct update. If the unit is in Workshop, please perform update as per Instructions.

Hi Gerard,
3 flashes of the led light on most KDL series is a power supply malfunction. To confirm the error code, lets access the self diagnostic screen by following the steps below.

Unplug the unit from the outlet for 30 minutes and then plug it back in and check if the symptoms remain the same. Wait until the led light stops from flashing and then press in rapid sequence the "Display", "Channel 5", "Volume (-)", "Power" button key on the remote control. Self diagnostic screen will be display. Let me know the result.

Sony KDL-40s4100 flashes and error code of 2 after about 7 seconds, then nothing. The backlight was on for about 2 seconds.

Have the same tv with the same problem. Changed the power board - no help. Next I changed the inverter board - no help. Only thing left is the LCD screen. I junked mine out. Hope I helped you out even if it wasn't what you wanted to hear.

No Picture on TV when Power is on

This seet should provide some diagnostic help. The standby light should be blinking a repeated count with a pause. Post that count here. Also, is there sound?

The above info will indicate the problem circuit which will then suggest the remedy.

Thanks,
Dan
