Atari 7800 Powering On / Off issues...

As stated in another blog, I have a few 7800 sent to me for repairs and eventual upgrades. This 7800 had an interesting problem where as soon as you plugged in the DC power to the console, it would immediately power on and would NOT turn off. While there are a few components in the mix that can cause, this, I've found really only two components well technically 3 that should be looked into as possibilities:   The first component and the one most people already know about, is the power

Get those Game Gears Recapped!!!

I know...I know... you hear it everywhere that everything in excess of so many years needs new capacitors and that will fix everything.

5200 with very odd keypad / fire button issues

I've done a video on something similar to this but here is a rundown on what I was encountering: A 5200 sent in for services had a note stating that top fire button wouldn't work on the console. This is an issue I've run into before and in fact have created a video on it. It can be due to the controller having a broken trace of course on the flex circuit inside it. But... it can also very well be due to a faulty 4052 MUX chip inside the console located at U13 or A13 depending on the age of
