Sony XBR-65A9F 3 Blink/Flashing help

@oldturkey03 Thanks! I’ll isolate the speakers, mainboard and see what error codes are thrown afterwards. I think (?) the T-Con board on this unit is a part of the mainboard. Honestly, there is not much to this TV all I see is two boards the power and the mainboard. I’ve added a pic of the power board that I replaced to the original post. Prior to replacing the mainboard and power board I had the same error code (3 blinks/flashes) as I do now once I’ve replaced both boards. I’ll dig into it tomorrow afternoon and report back. Do you know if I can enter into the service menu while it’s throwing the error codes? I’ve also tried a hard reset for Android TV’s per the instructions on the Sony site and nothing. When doing the hard reset, the TV boots and responds but after about 30 seconds it “clicks” at the power board and it throws the 3 blink/flash error.

Since both boars are new I figured that it is something that has not been changed that causes this. In some of the manuals I have it mentions that the audio can shut it down as well. Just trying to do this by exclusion. If it would be a software or firmware error it would not shut off like this.

@oldturkey03 I isolated the boards from the panel and I’m getting a white light with no errors when pull the blue ribbon cable from the mainboard; restart with the ribbon cable attached and it boots for 30 seconds does the full android start up with the Bravia logo then the power board clicks and its back to the 3 blinks/flashes. I’m getting the same 3 blink error when I pulled the speakers and the center channel input from the mainboard, with everything besides the speakers attached. There are only two boards and there is not a separate t-com board unless it’s between the frame and the panel. 1 of 2

@oldturkey03 For giggles I put the original power board back into the unit and the left speaker started clicking when everything was connected back together. I don’t think the original power board is bad, because that’s where I’m getting the white light with no errors when the blue ribbon cable is off the mainboard. I’m going to research and see if there’s a T-Con board hiding between the case and the panel. It could be the t-con board?

I uploaded new pics to my original post. Any thoughts? I’m really not wanting it to be the panel but it’s looking that way. It’s just strange it’s throwing a power board/audio error instead of a panel error. 2 of 2

I was surprised to see that speakers are listed as a cause for the three blinks as well. Follow the ribbon cables from the main board and see where they terminate
