I have half a dozen of these 2600 units and as Tony says the cart connectors are notorious for needing a clean , even the slightest bit of grot is enough to make the unit squeal and coloured lines appear.
8x out of 10 its a slot fault , I don't think ive ever had a 2600 unit fail on me in all the years ive collected and used them.
I do actually own a very rare Atari 2600 Test console myself which is usefull for checking joysticks and other bits n bobs.
They were issued to the retailers/service depts. so not on sale as such.
