Atari Lynx Bennvenn screen mod version 6 scanlines

[runner2019]

Hi!

 

Got this kit a few days ago from Zedlabz. Being version 6 it's got not a "backlight" pin at the rear to solder the scanlines wire to. Instead there's a "brightness" pin in the same location. I was told by the guys at Zedlabz to solder the wire here. I installed everything and soldered the wire both ends (the other end fourth upper pin on the motherboard). The screen works ok, but not the scanlines. The backlight or the brightness buttons on the lynx does nothing when pressed. Question is...there's a pin at the rear at the bottom of the screen labelled "scanlines" which wasn't present in previous versions. Do I have to solder the wire here instead of on the "brightness" pin? I threw the question to the Zedlabz guys a coouple of days ago but I think they're busy...Thanks

Hello there =]

 

According to the second photo, it definitely looks like an IPS V1 Rev3 (latest release), not a Rev6.

The first thing would be to confirm that, by simply checking what's written on the PCB (can't read it from here, it's in the shadow on the photo).

If that's indeed the case, just solder that blue wire to "scanlines" instead, and leave the "brightness" pin alone.

That's of course assuming the lynx motherboard isn't a C104129-001, be sure to check that as well beforehand.

 

If everything went well, you should end up with a working brightness wheel, and the backlight button (regular presses, no need to hold) should cycle through the 4 display modes (regular, scanlines 1, scanlines 2, and VGA-out).

Hi,

You were so right. It is a Rev. 3 (I don't know where I got it was a Rev. 6 from lol). I just soldered the wire onto the scanlines pad and it works and shows scanlines perfect now. Thanks so much!
