Hey guys

I just uploaded a video on Youtube on a possible power issue fix for the Lynx and figured it'd be something you guys woud be interested in:



Basically the Lynx II I got wasn't powering on from the power button on batteries and through googling I found a few threads here that discuss the problematic MOSFET on some Lynx boards. I suspected that until I powered the Lynx from an AC adapter and got it to turn on.

Looking over the PCB, I found two 100uf 35v capacitors that come almost directly off the battery power input, one of which had leaked so I cleaned it up and replaced both for good measure and presto! Worked from batteries again.

I thought it worth posting since I'd not seen it mentioned here and it may help someone else resurrect their Lynx.

The LCD in mine sadly turns out is screwed but any victory is still a victory :)

Thank you. You never know when you´re going to need it. Even if the Lynx is a very reliable workhorse, I know from experience how it is to fix something like this and I remember how grateful I was for helpful instructions, photoshots and video tutorials of minor DIY-console-repairs.

Retro Repair - Do you have any suggestions on how to fix my skewed LCD screen on my Lynx Mark 1:

As you can see it's the top Lynx and the backlight is showing around the top and right as the screen seems to have rotated slightly anti-clockwise. I took it apart and the whole LCD screen is one unit and won't rotate back.

Hmm. I've not had the Lynx LCD apart myself but I can see by doing a quick Google search that the LCD module itself does come away from the backlight unit, so you might be able to then use a bit of double sided tape to set it square before putting it back together.

Either way pay attention to the cable at the bottom of the LCD since if that rips (had that happen before) then you'll need a new LCD which won't be easy to find!

Thanks mate, great advice. I'll try and rotate it while being very careful :)
