    Hello,

     

    I have a 1702 that has a slight video defect. It's noticable; it bothers me; I don't know how to fix it. (It's been re-capped but the problem persists.) Beyond that, it takes up a lot of space.

     

    I'm hoping some folks can chime in here with flat-panel model suggestions, preferably with SVideo. I've seen a couple of suggestions (an RCA model at Walmart for $120) but they're only composite. A friend suggested a particular Samsung, but it's a security monitor and the current going price is $389. Sooo... no?

     

    I'm not married to any particular size screen, for whatever that's worth.

     

    Any suggestions appreciated!!!!!

    Ok. Isn't that an automatic computer/TV switch, rather than a RF modulator per se? I would assume it can be made to work with the C64 too, so there is a risk yours has gone bad after all.

     

    Correct. It's not an RF modulator. Even though there's a suspicious black box along the cable, I believe it's just a cable. Since it works with the Atari (which also has an in-built RF modulator), I imagine it would work the a C64.

     

    I've got a few things on the way to help test it. I have a replacement PLA on the way, better video options, among other things. We'll see. I verified the voltages today and did some probing with a logic probe and it's making all the right voltages and sounds so far. I'm hopeful.

     

    Thanks for replying again!

    What kind of cable does the Atari modulator end with? RF 2 Coax sounds like some sort of F-type adapter for the signal.

     

    If you would have a composite video cable suitable for e.g. an Atari 800XL, it would be usable on the C64 too. Or if you're handy, you can solder up one yourself if you have spare parts and don't want to pay for a cable just in case. What you'd need is a 5-pin DIN, some cable and suitable connectors in the TV end, usually RCA/phono plugs but I suppose it depends on your TV. Ground is on pin 2 (middle), video is on pin 4 and audio on pin 3. You can search for a more visual guide elsewhere on the net.

     

    Here's an image:

    This cable and box is the one that connects to the RF output of an Atari 800XL to a TV. The coax adapter I mentioned plugs into the coax input on a TV. The other end accepts an RF signal from a cable like this. I know the cable works with the Atari 800XL to this same TV. The 800XL also has an internal RF modulator.

     

    Does that help?

    The C64C has built-in RF modulator, that is the phono jack. Thus you don't need an external modulator, just plug the cable straight into the antenna input on the TV.

    What kind of cable can I use, though? Just RCA? I don't have an antenna input on my TV but I do have an RF-2-Coax converter.

     

    Thanks for replying.

    4 pins are normal. 2 are 5v and ground and other 2 are 9v AC.

     

    First, I would check the power supply. Stock power supply are garbage and they usually fail. If you don't have 5v DC on the 2 pins furthest away from the top (notched shield), it's dead.

     

    9 out of 10 times C64 has a blown chip when the PSU goes bad. Fortunately they are easy to troubleshoot and fix.

     

    http://personalpages.tds.net/~rcarlsen/cbm/c64/ has LOTS of useful into on C64, repairing and troubleshooting guide, etc.

     

    Thanks a bunch.

    I bought a C64c. It has a power supply, but there are only four pins on it which may or may not be suspect. The computer LED comes on. I connected it to a TV with an RF modulator. It's an Atari modulator, but I guessed it might be okay to use. The output, however, is a solid gray screen. (I don't have a monitor, otherwise I'd try that!)

    I don't mind if I bought a project. I'd like to try to troubleshoot the problem.

    I have a logic probe, a multimeter, and have some soldering and desoldering experience.

    Can anyone give some tips on what to check?

    I probably remember Demons and Diamonds mostly because it was one of the few Atari games I didn't understand within a few seconds of playing. Most Atari 2600 games had pretty simple concepts and controls. Sure some took a little (or a lot) longer to get, but this one seemed counter intuitive for me. I shoot something and it turns into the international symbol for death. It was just strange. I don't recall that I picked it up when it was new.

    I googled Pete and Pete. If that's what he was going for, he nailed it!! Pure genius, one of the greatest Youtube videos I've ever seen. Would love to see more videos in the same style and with the same type of narration.

     

    Wow Rhindle, I'm glad you like it so much! I'm really glad we have a fan. My video is up there too with my interviews from Bo Peep Show. Yes Pete & Pete is what he was going for, that's what he told me. Happy to hear that you'd love to see more videos in the same style because they are in the works they just take A LOT of time to make. Also cartoons are being made that are very ridiculous but funny I think you will enjoy them

     

    Thanks again :D

     

    Please give that man back his Atari Video System X, Joe. :D

    I can't wait for Test Drive 2 to come out, but beyond that the company could could broke and I could care less.

    What you acctually mean to say is I couldn't care less, saying that you could care less means that you do acctually care and could stand to care less than you already do.

    There are some phrases I can let past my inspection but that one is just plain stupid :P

    Turned out my PCB was bad, popped a nice rebuilt one in and I now have Galaga in my ghetto-cade, sweeeeeeeet!post-9102-128976791218_thumb.jpg

     

    Congratulations! What's really cool is you have the lower front artwork. It looks pristine.

     

    But what about that ultra-rare reverse-Galaga to the left of the machine? That's gotta be something, too, right?

    You can figure out Raiders pretty easily, especially if you use the hints in the manual. I know I did.

     

    The Swordquest series on the other hand, is pretty much completely random. Oh I know there are "clues" in the comics.. but give me a break.

     

    Looking back, I honestly don't know how my friends and I figured Raiders out. It wasn't a simplistic game. I can't remember the details, but I imagine we used the hints in the manual.

    all of the seaquest games, pac-man, ET, all the best

    You be trollin? >: o

     

    Why not try ET? It has a reputation but that doesn't mean you won't like it. I happen to think its reputation is largely undeserved.

    What are my chances of getting hold of one? ;)

    There were about 125 of them given out and just under 100 still out in the wild

    You know there has to be a box of them sitting around somewhere, some of the extra copies that were not handed out or just unwanted by the rich executive that didn't give a shit about Atari so they passed on the free gift. Unless they were destroyed which is possible.

    Maybe, :ponder:

     

    Do you have a box of them? :lust:
