ewokmic Posted January 13, 2013 Share Posted January 13, 2013 Hi All, Quick question. I bought a Jag from eBay a couple of years back and had it shelved for a while. The below image is what I am seeing through RF cable now. The game is working in the background but image is a mess. Tried fine tuning on more than one TV so that's not the problem. Any suggestions? Thinking of building an RGB cable - worth the bother? Thanks! Quote Link to comment Share on other sites More sharing options...
Gunstar Posted January 13, 2013 Share Posted January 13, 2013 It looks like you have it on the wrong channel for RF. The Jaguar has a high-low switch next to the RF plug, sometimes these are set (on various game systems) as channel 2-3 or 3-4. try changing the channel and/or the switch.

ewokmic Posted January 13, 2013 Author Share Posted January 13, 2013 Thanks Gunstar - new question - where do I find this switch? Using a plain RF cable, no switches or anything (been using it on my ST today too so working fine). Standard Jaguar official power supply.I can't find any switch on the console itself apart from the on off button. Inside? Happy to grab my screwdrives if that's the case.

+rdemming Posted January 13, 2013 Share Posted January 13, 2013 Is it a PAL Jaguar or NTSC? PAL Jaguars don't have a channel switch. If your TV has scart or you have an RGB monitor than an RGB cable is definitely the way to go because the picture quality is so much better than RF.

ewokmic Posted January 13, 2013 Author Share Posted January 13, 2013 It's PAL. Yeah I want to use RGB but worry that it will be a waste of time making one if the Jag is actually broken. Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted January 13, 2013 Share Posted January 13, 2013 Try adjusting your TV tuner a little either side of channel 36. You should get a better picture then. Quote Link to comment Share on other sites More sharing options...
ewokmic Posted January 13, 2013 Author Share Posted January 13, 2013 Tried on LCD and two CRT's but nothing better than in the screenshot. Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted January 13, 2013 Share Posted January 13, 2013 Did you try auto tune on the TV menu? Quote Link to comment Share on other sites More sharing options...
ewokmic Posted January 13, 2013 Author Share Posted January 13, 2013 Yeah, been tuning it using all known methods. Just had another try on a 12 inch CTR and no luck - similar to above picture but no colour. You can tell the game is running fine in the background. I'm thinking it's an internal issue for sure, but an easy fix or not, and would it be unrelated to the other non RF output (i.e. RF module may be broken but RGB would work???). Thanks all!

Actually, it just might work to change the cable. I had a problem with my S-video output on my Jaguar, color would go in and out and that progressed to the complete picture going in and out until it didn't work at all anymore. I had a home-made RGB cable on hand and tried the Jaguar with it and a monitor and it worked fine (I had tried to fix the S-video cable multiple times at first, even though it was never the problem). I've been using the same jaguar via RGB ever since and it's worked like a charm. I never did look to see if RF or composite video still worked, I didn't have the cables anymore. I did look at the motherboard at the time too, but there was no visible damage and no cold-solder points, though I never did check components, even resisters. RGB worked and that's what I wanted anyway. Edited January 13, 2013 by Gunstar Quote Link to comment Share on other sites More sharing options...
ewokmic Posted January 13, 2013 Author Share Posted January 13, 2013 Yes tried a different one and both working on other systems. Hmm. Well think I will build a RGB cable when I find some time and find out. If that doesn't work it will be hard to tell if its the system or my poor job, but we will see. Thanks guys.

Zerosquare Posted January 13, 2013 Share Posted January 13, 2013 (edited) Try a composite cable first. There are only two wires to solder for the video. http://www.atariage.com/forums/topic/156550-av-modding/#entry1921604 Edited January 13, 2013 by Zerosquare Quote Link to comment Share on other sites More sharing options...

Sorry, I meant to change to a different video output cable, like RGB, not just trying another cable of the same type. I'm with you that it is the system, and not the cable, but a different video out source may bypass the problem as happened with my Jaguar.

ewokmic Posted March 29, 2013 Author Share Posted March 29, 2013 Hi all - just to close of the story, I never did get the RF working, but I made my own AV cable (red/white/yellow) and the picture is perfect! After trying on so many TV's I guess the RF modulator thingy must be shot. No worries though because the AV is great! 4 Quote Link to comment Share on other sites More sharing options...
