repair Lost Vape Thelema Solo DNA100C repair

[skatingnobody]

Hey all! Not sure if this belongs here, but I’d figure y’all would know best. 
 

I have two LV Thelema Solo 100C’s. 
 

the first one, eventually the error message “Check atomizer” just kept continually popping up, and it no longer measures ohms on any tank. 
 

That one is is picture #1 disassembled… I have no actual idea, but it seems like that the shielding/sheathing of the black wire has slowly becomes exposed to bare wire over time. This may be the cause, but I’ve also dropped it many a times. 
 

I’ve looked/gotten into the actual board as much as I could without risking breaking the plastic carrier house holding the chip, and all seems fine on that end. 
 

Photo #1 and #2 are the second Thelema 100C I got to replace that one. 
 

Currently, the screen is extremely dark and just barely visible… but all is fine other than that. When I put light pressure on the bottom half of the fire button, without actually depressing the fire button, the screen just blacks out completely. 
 

I’ve been through Reddit and it seems that the cause is the silicone button shielding beneath the physical button but above the physical switch is actually being depressed into the screen’s video cable, causing that issue, but I’m also not quite sure. 
 

Since the #1 100C, I can take it apart successfully. 
 

So, my question/s is/are: 

 

What would be the most economical solution? (I haven’t got any electronics tools like soldering irons)
 

I’ve already got a cheaper Geekvape Solo 3 headed my way, but should I:

 

Save up for the electronics tools to re-solder the 510 connection on 100C #1 to it’s wires to check if it’s not the board itself? 
 

Should I attempt to use the functional screen in the 100C #1 as a donor for the 100C #2?

 

Or should I disassemble #2 and cut away a small part of the silicone switch shielding so that way it no longer interferes with the video/screen cable? 
 

Thank you folks

Yeah, good idea. It's already got a good bend it (#1), so it shouldn't touch the fire button in #2.

You can get a new replacement screen here;
