Hi all.
My 2nd light sixer, a Sunnyvale this time, arrived at home. It is affected by black screen problem. So I used the psu of the first 2600 I own, which works perfectly.
Nothing changed.
I've put the sunnyvale's TIA on the working 2600.. Black screen on it.
Placed the working 2600 Tia on the Sunnyvale.. Black screen. Sometimes shows colored vertical lines. I've try to Reinsert the CPU and the other chip.. Nothing. The voltage regulator put its 5v on the board, and 5v arrive on the connector of the shielded board too.
Suggestions? May I swap all chips from the working 2600 to the Sunnyvale?

I agree with osgeld the cpu is probably bad. I've had quite a few bad cpus in 2600s but no bad tias

yes they are all the same for the most part (as long as your not mixing regions on the TIA)

Damn, I've see that both junior version have chips soldered directly to the board. These are the cheaper versions of 2600 I can find on ebay
