A solder sucker didn't work and I have to order the de-soldering wick so I haven't tried that yet. It is both the battery pos and neg terminals touching the usb charging terminals.

I have a DNA 40 chip that has solder going from one connection to another. How do I clean off the old solder in between the two connections? Nothing I've tried seems to work.

Thanks for everyone's input.. I'll get the knack of this yet. lol..

What can you suggest for adhering the chip to the screen. For now that's my only option. Thanks again

Thanks Dave I appreciate your response. I've done pretty much all of what you're saying except for the poss and neg leads. I cut them to length then solder and place the battery tray in place. Building the boxes is my expertise but the electronic portion is a bit of a challenge yet. Im no stranger to soldering but I am on such a small scaled item as these chips. Why the lED came off the ribbon I don't understand but evolve will repair or replace the screen for me for a minimal fee. My issue now is securing the screen and the chip to the wood boxes I make. I've been told double sided tape heat range 200deg. +, silicone, glues etc. I wanted to get the 3d chip cradles and such but they wont fit in my boxes due to limited space. Im now looking for the best adhesive to use, and where to purchase it. Thanks again

tyvm for your help. Much appreciated.

Just my luck then for its a small screen and being nearly 60 yrs old my eyes aren't like they should be. LOL.. maybe Evolv will repair for me for a fee. Thanks guys

Finally found the issue and everything worked great so went to do the final install and the darn LCD screen broke loose of the cable..

While installing a DNA 40 into my box the lED screen broke loose of the cable. OH OH.. would it be repairable or is it toast now?

thanks awsum140 but while soldering I leave the battery out. Once I get one wire soldered then I'll install it and make sure the board itself is working properly and do the same for each wire soldered. That way if something acts up Id know which wire it giving the problem. After all the wires are in place it all seems to work great but I find that later in time when I go to continue to hook up the switches i'll test it one more time and POOF, there it goes again for no apparent reason...

I also noticed on occasions the screen would read "Atty locked press up and down" I would press the power up and down at the same time but nothing would happen..

This is the first box I've built from start to finish but having issues with the DNA 40 chip. I get the wires soldered on the chip and everything seems to work fine when I use the onboard buttons. All of a sudden the screen flickers and the power down mode seems to kick in with no off board switches connected yet. So I take the wires back off in fear of maybe a strand of wire is crossed to another terminal. I've done this 3 times now and seems to get better each time. The 4 time I rewired it I was able to start connecting the 510 connector and continued to the fire switch, the power up switch while checking the chip after each connection. When I got to the final switch (power down) it suddenly started to do the same thing. I disconnect both power switches hooked up the battery and turn it on and each time now it powers down to 0 without doing anything. Does anyone have an idea of why this is happening and what would be the cure? I hate to take all the wires back off again and start all over if I don't have to. Just about at my whit's ends here. I don't see any solder or wire strands crossing over any where.. Heeeeeelp!! lol

I noticed while trying to solder the recommended wire to the dna 40 chip the 24 awg wire fit well in the contact holes in the chip but the recommended 18 awg wire would not without fraying. I've tried both the solid stranded wire and also purchased the silicone wire which neither could be twisted enough to fit through the holes. So do you drill the holes larger or lay the wire on top the holes in the chip and solder over them? If the wires don't fit what purpose do they serve? Thanks

Thanks for your help. Much appreciated

Im getting ready to wire up my first DNA 40 chip. Before I do does it matter which 2 prongs out of the 4 I use on the C&K tactile switch for the power up and down? Also does it matter which one is used for the positive side and the negative side?
