Sony Bravia Standby Light Blink Code 4

I recently had an issue with my TV and I received a blink code on the standby light 4 times. And despite my internet search I was unable to figure out what the fault was from that code. I called Sony tech support and they told me I needed to have the TV serviced. So much for the support. So here I sit waiting on the TV technician who basically got here and called Sony Tech Support and gave them the work oder number and told them the blink code. Shortly after breaking one of the plastic pieces holding in one of the power supplies he asks for a paper clip in order to jam it into the connector to check the power supply.

What I’ve learned. I have a bad power supply board in my TV. Blink code 4 on the Standby light on a Sony Bravia is a backlight problem. So that can be one of a couple things. Either the Power supply board or the inverters that drive the light. If it’s the inverters you pretty much need a new TV. If it’s the power supply board it’s about a $250 part plus the labor. The output of the Power Supply Board in the Sony Bravia should be 18V. Mine has a 7V output, so that seems to be the problem. The yellow board in the picture below is the Power supply.

The Power supply board is connected by 3 connectors and is screwed in. If you have the means to get a new board. It’d save you almost $300.00 in labor costs. You don’t get the limited warranty if you replace it yourself, but there you go. Hopefully this will help some of you out.
