Does the front light stays green ? Or goes back to red ? The back-light going on/off maybe the problem, but it shoul return with a red blinking led (4 times ?) and if so it can be a power inverter problem.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

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

That symptom may cause by the main board or t-con board, I suggest you do software up grade first.

Hello, thank you for your question about the front lights. When I turn it on, the light in front comes on to green for a split second and then the red light comes on for a second and then back to green which stays on. Thanks!
