I just got my Centipede cocktail working I’ve the last few days and I can attest that I hate the Matsushita monitor. Everything on it is hard to work on. Mine is also suffering from brightness; but it’s the blue channel on it. I’ve got it working well now though.
So much so that I was prepping it to sell as we are cleaning my garage full of projects out; but, now my niece love it and wants to keep it. So, it’s only the Asteroids Deluxe cocktail for sale currently.
