Do NOT try to move a SMD device without heating all the pads. You will
break something. Go to the local hobby/hardware store and get a heat
embossing tool. Mine cost me 10USD from amazon. Or use a low temp
alloy like from ChipQuik to remove the device then clean and
reinstall.

I have this problem too. What is the best solution? I have not hot air gun, only regular fine tip solder.
Heat Q103 drain tab and squeeze a little with the pliers to the left? Any chance to do so?

Don't even need sewing needles! Armed with the cameo schematic, normal probes on gate and drain of Q105 should read about 100k if no short between drain of Q105 and that BSS123 so close by.
Mine reads 95 and 99 point something either polarity convincing me I don't hafta slide Q105 to the right and maybe my QMX won't catch fire on first power up!
Thanks, boys, for providing this topic and solution!
