Hi Elaine!

Please follow the steps mentioned below to troubleshoot the issue:
If the TV standby light is blinking for five times then you may perform the steps given below:
(i) Turn off the TV then disconnect all the cables from the TV.
(ii) Next, reconnect all the cables after two minutes.
(iii) Please make sure that the power cable from the TV is directly connected to a functional wall outlet.
(iv) Next, you may try resetting the TV to the original factory settings.

Please follow the steps that are mentioned below to reset the TV to the original factory settings:

(a) Turn ON the TV.
(b) Press and hold the Power button on the Remote Control supplied with the TV, then press the Power button on the TV front panel.
(c) Release the Power button. The TV will turn itself off, then back ON again.
(d) Next, release the Reset button on the Remote control.

If the standby light still blinks then the issue may be with the projection lamp in the TV and requires replacement.

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

sorry. Hope you still have a waranty. This is not an uncommon problem with the sony's. 99% chance that the panel went out. Could also be a balance board issue, but usually not. Call Sony for an authorized repair center

We have a 2007 Sony Bravia 46" KDL-46VL130. There is not sound or picture. When we power it on the green light comes on blinking once and then the red light blinking once and then the green light stays on....


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.

The green light merely indicates that power is getting to your TV. The symptoms you describe point to internal power supply failure
