I've been working on a light sixer. I did the A/V mod, replaced the power switch and an LED power light mod. The problem is that I will switch it on, anywhere from about a minute to 5 min the display and audio go off. The LED stays on but nothing else. I'm not sure what else to try. I've used the power supply on another Atari and it works great, Any ideas would be appreciated, thank you!
