Hi!
I am trying to repair my childhood Intellivision console, a PAL 3668 revision. It has been in storage for over 30 years, and I have not yet plugged it in and tested it. I want to inspect the board first, and see if there are any potential errors before running power through it. I have very little knowledge of electronics and soldering, so obviously I have some questions..
First, I found this component that seems to be leaking:
I did a search, and this seems to be a 4.000 Crystal Oscillator. Does that mean a 4Mhz crystal like this would be a valid replacement?

Here are photos of the board from the top and bottom:
The underside has these brown splotches that look like leaks as well. Should I be concerned about these too?
Should I also open the RF housing and inspect it?
Any help would be most welcome!!
