newTIboyRob Posted December 22, 2023 Share Posted December 22, 2023 In continuing with my previous post, this time I have a beige 4/a in cosmetically pristine condition. (Shocking really considering its 40 + years age.) However, when I tested with the power supply and RF box from another system, I just see a blank screen, hear swishy sounds, then a low hertz hum and see no cyan TI start up screen loading. But again, if you like to/want to tinker, or if you need this for key parts or just need a shell in stunning, just-out-of-the-factory condition, feel free to PM me. You will soar in that capacity. 3 Quote Link to comment Share on other sites More sharing options...

Very cool rehoming 99s. I have never had a Beige so I reached out, just in case. Quote Link to comment Share on other sites More sharing options...

I have a similar issue, but complete new Beige TI, but it worked before tested a few times and put in the box, last time I tested only a black screen. Normally it are the video chips having the issue. There are several forum websites talking about it https://www.nightfallcrew.com/22/06/2013/texas-instruments-ti-994a-diagnosing-and-fixing-motherboard-faults/ Quote Link to comment Share on other sites More sharing options...

Appeelicious Posted December 23, 2023 Share Posted December 23, 2023 I'm going to need to order a chip tester at some point. Quote Link to comment Share on other sites More sharing options...
