Flashing Amber and Green LEDs [Solution]

Post by rippetoej »

I recently had to replace the BA board (the one with all the AV inputs) in my girlfriends NSX-40GT1. Upon powering on the TV, I was greeted with two LEDs on the front panel of the unit flashing in sync. The power/standby LED was green and the sleep timer LED to its left was amber. Because this particular LED code doesn't appear to be officially documented anywhere, I had to do a bit of digging around on the internet to come up with a solution. Since these forums were so useful in helping me get everything I needed, I thought I would post what I did to help others avoid having to do the same. This process should theoretically apply to the other models of this TV (24, 32, 46), but I cannot say for sure. As always, you should also proceed with caution when flashing firmware to your system as being careless could brick your device.

After some searching I came to the conclusion that the TV needed to have the system firmware reflashed, something that is likely done when Sony services the devices (explaining the lack of documentation for the LED code). Before the board was replaced, the TV was running the latest stock Sony firmware from 9/17/2012, so I downloaded that from this thread here. While I can't say for sure, it would likely be a good idea to reflash whatever firmware you already had on the TV before, especially if you aren't replacing the main processor board. Every Sony OTA update is available in the NSX-40GT1 wiki on this site through a link found under the USB update section.

To do the update, I followed the instructions found here which I have replicated below. The file will need to be renamed according to the particular firmware version that you downloaded. For me that ended up being "package_list_DMA-1_ASURA_2012091701_AAV_ORSC.zip". Asura is the codename for the TV and Eagle for the blu-ray player.

Getting the update started is where things got a little hairy for me. I followed the instructions below to the letter and was expecting the update process to begin and a message to appear on the screen telling me it was doing so. Instead, after powering on the TV I continued to see the two blinking lights on the front of the set. At this point I left it on and turned around to do some more research, only to turn around about 5 minutes later to find the expected "upgrading" message and a status bar indicating the process was nearly complete. The sleep timer LED was still blinking amber, but the power/standby LED was now solid red. At some point the system must have recognized that there was an applicable update stored on the USB drive and begun the update. After the update I was pleasantly surprised to find that this process does not wipe your user data, so no initial setup was needed.

I hope this can save someone else the time and agony I spent!
