Ballblaɀer Posted March 30, 2016 Report Share Posted March 30, 2016 Just scored my first Lynx for cheap. Lynx I with the OEM carrying case and about 10 games. Super excited. When any game is inserted and the system is powered, the speaker pops, and the screen comes on, but blank (backlight only, I suppose). No sound, no *insert game* message, nada. I've looked through a lot of old AA (and other) posts to try to figure out what may be wrong, since it seems this is a common symptom. From what I'm reading, it seems like a voltage regulator and/or zener diode may have failed, and unregulated 9V could have fried some important things. Could be something less serious (like voltage too low), but... prospects for a fix aren't fantastic. I opened the Lynx up to see if anything looked out of the ordinary. Couldn't see anything obvious. Nothing looked cracked, burned, or otherwise amiss. I have not yet removed the RF shield; I realize the answer could be underneath. Can anyone recommend a plan of attack for testing/fixing? I am not exactly handy with electronics and have never soldered anything in my life, but a friend who lives close by has enough experience for the both of us together, and presumably all of the material/equipment we'd need. I suppose my questions are:- Is there anywhere specific (other than underneath the RF shield) I should be looking for visible failure that I may have overlooked? - If anything higher than 5V is measured on the +5V rail (i.e. multimeter/voltmeter reading at TP15, or somewhere else?) should we assume that it's a lost cause? - Is there a field service guide or some other type of helpful flowchart/troubleshooting reference (other than the board schematics) to be found? Google didn't seem to think so... Thanks for any/all help! Link to comment Share on other sites More sharing options...
