Hi guys,

  was prepping my Lynx 2 for a McWill mod last night.  Pulled off the caps, moffit, Zener diode and then went after Q7/Q8 transistors.  Of course, with my luck, I pulled the pads off one of the transistors.  (sorry, can't tell if it's Q8 or Q7, i THINK it's Q&)

I'd like ti fix this of course, so I can trace the botton pad to the via easily (part of the pad is still attached and I checked for continuity.  For the top pad, it looks like it's directly connected to R74 (sorry, didn't get it in the pic.. http://atariage.com/forums/topic/183941-atari-lynx-ii-mosfet-q7-m6-or-l6/). Is this correct?  I could wire something directly there, or use a dental tool to remove solder mask to expose a new line, would that be better than directly connecting to the resistor?

 

 

 

So much more complex than adding a backlight to a gameboy!

I would use a wire to the resistor. In this case trying to solder to the trace makes a very weak connection compared to  soldering a wire.

Thanks, I checked continuity between that resistor, the one right below and the pad, they're all connected, so i'll connect a wire between the resistor and transistor.  Thanks!

Follow up..wired to resistor and it worked. Got my McWill screen installed and is working perfectly. Thanks.
