nosweargamer Posted September 21, 2014 Share Posted September 21, 2014 Hi guys. I recently bought a modded 7800 off of ebay with a RCA A/V mod. I wanted it to get a cleaner picture than RF and for recording for my youtube show. However, when I tested the console I bought, the picture was worse! I noticed several scan lines and dots and when I tried Pole Position II, it even had occasional horizontal line flickering. What I wanted to know was this: Is this normal for modded 7800 systems since they weren't originally designed for RCA cables, or is this due to a lower quality mod job?

Trebor Posted September 21, 2014 Share Posted September 21, 2014 It could be a fault with the mod job, but it could be also due to the display you are using and how it handles the composite signal. I've seen some HDTV's look good with composite and some horrible. If using a CRT, then I would more strongly lean on a problem with the mod job; however, it is always best to test on another display as well, to definitely rule out the device you are watching on is not the source of the problem(s).

Agreed, recheck all connections and, if possible, plug it into a CRT display. If the CRT display doesn't look clear and crisp then the mod was likely botched.

nosweargamer Posted September 21, 2014 Author Share Posted September 21, 2014 Yeah, the same thing happened with both my HD and CRT tvs. I even tried with different RCA chords. So I'm guessing it was a lower quality job. If you have a modded 7800, do you notice a cleaner, better picture? Quote Link to comment Share on other sites More sharing options...

I can't verify this, but I believe the composite (RCA) mod should look just as good. Quote Link to comment Share on other sites More sharing options...
Trebor Posted September 21, 2014 Share Posted September 21, 2014 I have a composite mod from Yurkie, a Best Electronics composite mod, and one from Electronic Sentimentalities...They all look great on CRTs...Varying results on HDTVs depending on the display.

yell0w_lantern Posted September 22, 2014 Share Posted September 22, 2014 I have an Electronic Sentimentalities mod too. It looks quite good. I did have to install the switch for disconnecting TIA pin 9 when in 7800 mode. Quote Link to comment Share on other sites More sharing options...
Andromeda Stardust Posted September 22, 2014 Share Posted September 22, 2014 Mine is the AV mod from Best. No switches to mess with; 2600 and 7800 both work fantastic. Sound is noticeably cleaner than on my 4-switcher RF. Some 2600 games looked a little off or over-saturated, but all my 2600 homebrews display correctly. I realized many early Atari games had gut-wrenching color schemes as they looked bad on my 4-switcher too. Quote Link to comment Share on other sites More sharing options...
