tater1337 Posted April 13, 2019 Share Posted April 13, 2019 HiI went to a hamfest/swapmeet the other weekendand there i saw it a TI 99 4A, the first computer i ever bought, back when I was 13I thought 'I'm 50 now, I can afford to splurge on something nostalgic, considering it has formed my career life since I got it'bought it, hooked it up, no light on RF modulatorhmm, maybe I should check on the net to see if there is some infomany google searches later (and all the youtube videos and a purchase off craigslist for another unit) I go to a forum and post HiI went to a hamfest/swapmeet the other weekend.... so I am not quite sure where to start(FYI, din plugs from amazon are on the way to build cable to test while waiting for delivery of other 4A unit) Quote Link to comment Share on other sites More sharing options...
jaybird3rd Posted April 13, 2019 Share Posted April 13, 2019 The original TI external RF modulators were and are notoriously flaky; even back in the day, I had a lot of trouble with the DIN-5 connectors and went through several replacements. Fortunately, the DIN-5 port on the 99/4A outputs clean composite video and audio signals, so with a simple cable, you can connect it directly to the yellow/white inputs on newer TVs without having to deal with RF at all. Here is one such cable (not mine): eBay Auction -- Item Number: 142838271907 1 Quote Link to comment Share on other sites More sharing options...
xabin Posted April 13, 2019 Share Posted April 13, 2019 (edited) We have that kind of problem, too. No one told us that the RF modulator were flaky. We'll feel really dumb if it turns out it is the RF modulator, this time... To the OP: Are you having the same visuals we're getting, ie. snowy/black screen with an audio buzz?

To the OP: Are you having the same visuals we're getting, ie. snowy/black screen with an audio buzz? none at all but i did some tinkering and got a cable to give me video, if I hold the wires just right like I said, I am waiting for the 5 pin DINs to show up and i'll make my own cable. played a few carts, the 2nd 4a has a boatload of carts Quote Link to comment Share on other sites More sharing options...
Airshack Posted April 13, 2019 Share Posted April 13, 2019 Even a working RF modulator is vastly inferior to the composite out. I’d recommend ordering a composite cable. The C-64 and Atari 800/400 cables work on the TI-99/4A as well. Sent from my iPhone using Tapatalk Pro 1 Quote Link to comment Share on other sites More sharing options...
