I don't know of any video tutorials, but i'm sure there are some on youtube. This is basically how i do it though:

All you need is a soldering iron and solder. heat it up, now add some solder but not too much, and apply it on that part underneath the removable strip near the bottom area of the panel. Don't be scared to heat up a certain area for a long time. You should be able to see what's happening on the screen as you're doing this. Make sure the contrast is set correctly. It may take a few tries, but just move the soldering iron across every few seconds, back and forth consistently, and you'll see every single line come back. I'm pretty sure that should do the trick.

Horizontal lines are the ones that can never be fixed, i've tried before and it was awful. i tried to heat up a paperclip and gently press it against the horizontal screen ribbon to heat it up slightly, but instead it cut right through it like butter lol.

I didn't use solder when I did this but I used a hot soldering iron and it did make the lines reappear but every time I lifted the iron, the lines would disappear again.  Kept trying and trying but it never works for me.  Tried it on numerous DMGs before I gave up.

Sometimes the lines disappear when you remove the iron, only to come back when the solder underneath cools down.

You might have some flux residue afterwards, but that's easy to clean.

Interesting. I've repaired more than 10 "broken" DMG's from craigslist with vertical lines and every single one of them have stayed permanently fixed for years now.
I've found that it definitely depends on the amount of heat being applied consistently with the iron.

Maybe it's just the different extents of damages that we've had to deal with, but you guys can feel free to buy full price gameboys all you want
