ok... so i got all my soldering crap set up and ready to give the steps in the youtube video my 100% best.
the pictures get bigger if you click them.
i cleaned the area to be soldered with rubbing alcohol, lightly wirebrushed it, applied a no-clean flux, and used my AOYUE SMT soldering station to heat and spread the flux.
then i added solder to each and every contact point down the line.
that's really all they did in the video besides resoldering the connector pins. i also did those but i'm skipping writing about that.
after following the video, i went above and beyond. i unsoldered the tin shield from the board so i could inspect the connectors at the glass
they looked OK from what i could see.
but i went ahead and lightly wire brushed those and added a bit of solder anyways. it may look slightly messy but it's magnified 36x, and glass/heat scares me, so i was trying to heat these minimally as to not shatter the screen.
after that i wanted to see what was on the mysterious hidden middlecircuit board.
just a lot of LED's on there. you can see a few in the pic.
while i was looking in there, a red plastic diffuser lens started to fall out. so i temporarily removed because i'm not one to quit while i'm ahead (if you didn't notice by now).
this is how the screen looks without the diffuser behind it, just in case anyone was as curious as i was. and yeah. 3:23 AM.
next morning, all back together, the "1" in my radio station "103.5" is still funky.
today(below) it works perfectly. i assume later it 'll be back to looking like the picture above.
so now i'm thinking that there is a bit of corrosion under these press fit connectors where they contact the edge of the glass. i feel that glass is prone to condensation, and therefore corrosion. i also feel like this is why the screens sometime get better or worse when you tap on them. i want to remove these and attempt to clean the contact points, apply grease, and see if that does the trick.
they look like they just clip on/off, but i don't know and i'm a little nervous to start yanking on things. i may sign up on an electronics forum and direct them to this post. (EDIT: I asked the gentleman in the video and provided a link to this.) maybe he will be able to give me some confidence moving forward. if not, i'll drink a bit and get some liquid courage.
