There are many existing post and replies on this topic, I suggest you use the forum search to try locate theem and the answer you need is probably already on the forum somewhere.

You might want to follow the flowcharts in the Atari 2600 Field Manual to help diagnose what the issue could be.

This has been covered in lots of posts in these forums over the years. But I will give you one place you need to start with. You stated that the power supply is good yes? Then the next step is to verify if the voltage regulator on the system itself is working. As from the left pin to ground it should show that input voltage from your power supply although might be a bit less given the extra load from the 2600 when plugged in. And from the right side pin to ground you should see around +5v. If you aren't, then you know where you need to start. Again, the first rule in stuff like this is.. to ASAP.
