And likely dry solder joints on the power feeding the left two lcds. You can often see a feint but visible ring in the solder and if you do reheat the solder and add a touch of fresh solder. If it is the right spot theres a good chance of bringing it back to life. No idea about the insides of these but thats a typical generic fix for most old partly failing electronics.

I agree that, that’s often the case but I couldn’t spot any, I’ll post some pics tomorrow

Thanks for posting that link the1, I had no idea about that thread, what a great read
