Channel F ver. 2 freezing up after few seconds

[frenchmarky]

I just yanked my Fairchild Channel F console out of storage after 10 years and hooked it up.  It had always worked before but now whether I have a cartridge in it or not, it will only work (game loads, buttons work etc.) for the first 20 or 30 seconds after I power up, after that it freezes up with accumulating garbage on the screen.  If I turn it off/on quickly, it just starts out frozen, the game has to be off a minute or two before it will begin to load correctly.  All I have done so far is reseat the one socketed chip inside but no change.  Any suggestions on if it is fixable and what else to check, like the two big electrolytic capacitors are just dried out maybe?  I really want to get this working because I just ordered one of those multicarts.  Thanks!

False alarm, I reseated the chip again and unit is solid now so I'll clean the chip and socket too.
