@Ceaser,
If you are going to own an Amiga system, you MUST NOT be afraid to remove and reseat chips and components. That's common sense 101 when dealing with vintage computers.
Using a very small flat blade screwdriver, you may carefully pry up one end of a chip (I.C.). When you feel the pins have moved up slightly, you may then press down on the chip to reseat it. That "fixes" most chip/socket problems. If not, the more aggressive thing to do is remove the chip completely (working your screwdriver from one end to the other carefully and slowly) and press it back in again.
Save 2600 though you are a long time amigan and vintage collector I dont think this is good advice at all especially for a noob.
1. If you are NOT comfortable working on your vintage machine yourself Please DO NOT do so and get an expert who can. Preferbly a dealer or former service tech.
2. DO NOT use a "screwdriver" on ANY chip extraction if you can help it. Use the proper tool. (an ic chip puller) Not sure why he recommended using a plcc pullern (which is correct for socketed PLCC chips - even though this Can be done with a screwdriver if you are foolish) and not recommending an ic puller instead of a screwdriver for the other chips..
