The problem could be in the controller module, I've heard of the USB port developing a cold solder type of problem where if you wiggle the USB cable, the video may come on again. The problem could also be in the bird itself not transmitting the signal, in the link between the camera and the drone, or like you suggested, in the video module in the camera which at this point seems to be the most likely scenario. It can record the video to the micro SD card but it can not reproduce it. I can see how many videos have been recorded to the micro SD from the controller but not play them back.
The problem was there before I performed the FW updates. Yes I did have the RC transmitter on as well.
If you still have the SD card with the update on it , try and look at the log, it will be the one on the very bottom of the page . Bet you it says"device Not connected " on lines 0800 and 1500. If you still have the SD card the data will be on it . If you dont have the SD card then you could try to reload the SD card with the UPDATE that you did last and then try and read the log. Hopefully you have the original SD card as sometimes trying to load the SD card to the AC wont work if you have the 'Device Not Detected " on lines 0800 and 1500 .
IN the future NEVER have the RC transmitter on when updating the Aircraft, ( I know you say the problem was already there , just for futrue reference ) I would still just return it and start over otherwise you will need to send the camera into DJI for repair and that can take weeks .(This was not your fault ! ) Dji instructions are terrible .
If everthing else works, you can start the motors and you get telemetry data etc and can record to the SD card JSUT NO LIVE VIDEO then I say with near certaintly that the problem is. a corrupted video module on the camera that happend as a result of having the RC transmitter on when updating the Airicraft ( or other reason ) . It wont happen every time but I have seen a significant correlation in the two. DJI does not put enough empahsis on this and I think it is a dam shame .

before you do any updating read my tips page and it will help you .
I will give you two links , one is how to read the log off the SD card and the Other is Tips on updating the RC and AC . Also Always update the Aircraft first .
Tips: Loading NEW firmware to RC and AC- Insp. 1 Phantom ADV & PRO
How to View Hidden Files: Diagnostic tool for SD and No Signal Issue
***The problem is NOT in the RC transmitter , I consider myslef almost an expert on this particular problem and can almost say with certainty ( Anthing is of course possible ) that the Encoder module has failed on the Camera itself . If you can check the SD card we can confirm this , lines 0800 and 1500 .
***ON the go app with the entire system on what versions of FW do you have on the system ( go the "about " tab on general settings , it is towards the bottom can you please take a screen shot or just list them ? AC -RC - camera - and go app versions please . I have one other idea possible but if you are up to date it wont matter . sample below ( Not current fW on the sample but gives you the page I would like to see )
