Standby light flashing but no pic no sound on

try some of the solutions on this link hope one will work for you. http://www.docs.sony.com/release/KDL32S20L1.pdf look under troubleshooting for no picture good luck

Hi,

Flashing green standby led light at the front panel is an indication that the unit waiting for the lamp to turn on. Since the lamp led light flashes, the unit sensed it already burned out.
Faulty lamp driver has a different error code which is "flashing of the standby light 5 times".
Your unit will back to normal operation again after the lamp replacement.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

The service manual lists 3 blinks as the light cover not being secure. it has a micro switch behind the cover so if you hold down the switch you can see if this is the problem.

how many times your ligth blinks?
5
if so you need to check your g2 voltage
let me know so i can get you more details

Sounds like the lamp is bad. Might be time to replace the TV.

id take it and have it repaired. people on here can tell you what they think it is but no one knows for sure what is causing the problem. a repair shop can guarantee the repair.

The STANDBY light is flashing on the television and there is no picture or sound. Solution
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.

1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
   
2. Unplug the television power cord from the electrical outlet.
3. Let the television remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
   
5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
