I picked up my first Lynx and about 30 games at the weekend. It's a Lynx II in great condition, and with it came two other brand new and boxed but non-working Lynx IIs. They were dead on arrival when they were new, so even if I can't get them working they might be useful for spare parts. Dead Lynx A completely unresponsive: I tried with both fresh batteries and a Lynx PSU and there is no response when I press the 'on' button. I tried connecting the negative battery terminal to the negative (ground?) pin of the speaker jack (which I saw in a YouTube video) - when I did this the screen backlight comes on but there is still no response. Problem Lynx B works perfectly except for the screen display being fixed solid black. The backlight switches on and off, sound plays, buttons respond etc., but the 'brightness' setting does nothing. Again I tried both batteries and a PSU. I tried switching over the motherboards of these two machines, to see if Lynx B's problem is just with its screen, but there was still just a solid black image. I was wondering if I could swap a McWill screen into this machine, but I'm not sure if this problem would persist with that screen too- is there any way I can test whether that would work? Is there any other A/B testing I can do between these two machines to help identify the problem components? Are there any other standard things I can test for? Thanks in advance!
I had just done a McWill update and everything was working great. It ran fine for a few hours and a few on/off cycles, then I couldn't turn the Lynx on. I assumed the MOSFET has failed, ordered a couple, put it in and then POP, TP18 blew up real good! Perhaps I didn't purchase the right MOSFET, or just a coincidence? This is the MOSFET I ordered from Digikey: NDT2955CT-ND NDT2955 MOSFET P-CH 60V 2.5A SOT-223-4 Assuming nothing else blew and I have the right part, I've heard there was a zener diode I should be replacing as well, but I don't know which one or it's value. I, of course, need to replace TP18 -- what part is that? Thanks in advance to you all.
