davidbrit2 Posted May 21, 2017 Share Posted May 21, 2017 I've got an NTSC Vader, and it's had a fairly dim picture since I got it. I bought a composite video mod kit from ebay (the basic kit with one transistor and three resistors), and it worked great - the picture is much cleaner now - but it's still pretty dim. Is there something I can do to adjust the brightness of the output at all? Are there perhaps some aging caps that need to be replaced?

Jeremy Popp Posted May 22, 2017 Share Posted May 22, 2017 There is a color adjust dial under the shielding on the left. I would recommend marking its current position before adjusting in case you need to return to factory. There is also a resistor mod/factory addition you can add to boost color on 4 switchers. There is a thread somewhere here in the forums. Quote Link to comment Share on other sites More sharing options...
davidbrit2 Posted May 22, 2017 Author Share Posted May 22, 2017 Yeah, I used the Color Bar Generator ROM to calibrate the hue pot, and the color saturation looks okay (maybe even a little bit too saturated), but the picture overall just isn't very bright. My 7800 seems slightly brighter, though it's not a night-and-day difference. Quote Link to comment Share on other sites More sharing options...
