No TV Connected - ATI AiW

masterful · 01-31-2002, 11:54 PM

Ok, I finally managed to get a hard drive that wants to work for me. Got everything running the way I want it, and hooked up my 5" Legacy LCD to test everything out . . . and now I'm stumped. I have an ATI All In Wonder (old version, think it's the 8mg type) and when I go to the 'Display' section in properties of Win98, it says there is no TV connected. This doesn't allow me the option of turning on TV as an option. I am using RCA's plugged in to the purple external jack box thing that came with the card. The 'purple jack thing' I'm referring to seems to have a proprietary DIN type plug that then splits to S-Video, Composite Video, and RCA Audio external to the card. Any recommendations? I've searched the forum, and I'll grant you, I didn't read every message I found, but I did read about 80 out of the 132 found, and didn't see anything. Looks to me like no one complaining about the same problem.

p.s. I know the LCD works, cause I output my DSS receiver to it and it worked beautifully. Thanks for any help.

click on the link in my sig. Notice the part about 75 Ohms resistence under TFT-LCDs

That would explain why I can start the computer with the Video out hooked up to my Sony 36" TV and it work great. Wait till it's up and running, unplug the video, plug it into the 5" LCD, and it work too eh? Needs the initial resistance to tell it that a TV is present, then it supplies the signal. I understand completely, and I appreciate your response more than you'll ever know. One last question . . .

How in the name of God do you guys figure stuff like that out? I suppose it comes with electronics knowledge. Me? I'm just a poor ole Network Engineer/Computer freak. I suppose I should start getting more into the electronics side of things. Almost got hooked back with my arcade machine project (check other posts by 2119), just backed off of it when that project was over, and haven't went back. Anyway, thank you so much.

He He...I didn't think of it either. I just know where the FAQ is

Ok, you're not going to believe this . . .

There is not a single Radio Shack in the entire city of Tulsa that has a 75 ohm resistor. The closest they have is 72 ohm, and 82 ohm. My question is, will an 82 ohm resistor work for this application, or no? Like I mentioned before, I'm a little short on the electronics knowledge, but logic would dictate that if something wants 75 ohms, and gets 82, that the minimum 75 ohm resistance was met, and therefore could proceed. Logic doesn't tell me whether or not the extra 7 ohms will present a problem with the signal, or anything else for that matter. btw, it is an: 82 Ohm Resistor 1/2 watt, 5% tolerance.

Please let me know a.s.a. you can so I know if I'm going to have to drive around looking for another shop.

As always . . . thanks in advance.

Jeffrey.

It should work fine. For confirmation, check this thread: http://www.mp3car.com/cgi-bin/ultima...c&f=7&t=000111

Buy the 72 ohm, along with either a 3 ohm or 3) 1 ohm resisitors. They can be connected in series to obtain the proper rating.

BTW 75 ohm is the standard for all video, and although they will work for short distances/low resolution, DO NOT USE NETWORK COAX CABLE FOR VIDEO They are 50 ohm cables.

I had thesame problem with thesame card and all I did was plug in the computer to a monitor then got a small wire peeled both ends then I stuck one end of the wire in the hole of the RCA TV out cable then the other end is supposed to make contact with outer part of Rca Cable, basically I joined negative and psitive together, then went display settings and TV is now available, checked it, then shutdown computer
then took wire of put computer in car and hooked up composite video LCD and presto.
I guess the video card keeps last settings.

Ok, I gave it a shot (82 ohm resistor was all I had this weekend on my trip to BFE, I'll try the 72+3 option also), and it didn't work. I still got nothing. I'm thinking though, that I don't have a real clear idea about the wiring. I cut an RCA video cable in half, stripped and stripped the wires down. I ended up with the shield wires, and the center pin wires exposed for each half of the cable. I then soldered the shield and center pin wires to one end of the transistor, and the same thing on the other end of the resistor. I'm thinking that I'm not supposed to have the shield wires and center pin wires shorting across each other, but then I don't know enough about it to do anything but speculate. The two information sources you guys have supplied don't really lay it out in 'dumb' enough terms for me I guess.

Someone let me know if I'm crazy here . . . thanks.

I have to do this yet for my lcd, but what I got from reading the FAQ, etc is to attach one end of the resistor to the center wires and the other end of the resistor to the shield wires in the rca cable.

Hey, it just so happens that I can tell you what computer that video card came out of.

It was a Sony VAIO model PCV-130 -or- a model PCV-150. now, that card is made for windows 95 with as far as I know, no support for 98. However I have one of these systems (typing on it right now) and in playing with it and putting 98 on it, I found the same problem that you did, there are no controls for video output in the display settings, but there is an option for it in the display settings help section provided that you downloaded the drivers from sony's site.

hope this helps

--EDIT--

Also, there is a TV tuner built onto that card which alows for watching TV or NTSC video from any source. anyhoo, the extra cable's you were talking about with the strange purple piece, these are video in. Same with the RCA and S-vid connection on the top of the card. the vid out is the inner RCA and S-vid connection.

Hope this helps again.

It is not connected correctly. Nutzy is correct. Look at the diagram in this post.
