Fixed Glithy Display still Glitchy

since they were solder fixed, try pulling the cable out a tiny bit. pushing it all the way in can cause issues due to the dimples that form on the cable. (i don’t know the technical term for this, perhaps someone else can elaborate).

my glitch issues appeared on games with more red, such as some of the ones you have mentioned. games with simpler graphics didn’t give me issues. after i got them solder fixed i also had some glitches. it was dogp whom suggested pulling the cables out a tiny bit after seating them. that fixed my problems.

the black lines could be dust on the LED cover. you can try some rubbing alcohol and a q-tip.

the part you slide into the LIF socket. you screw down the LED part and then the other end slides into that little socket? that is the part, just pull the cable back out a fraction of a mm, instead of pushing it in all the way. what i did was push it in until it stops, then pull it back out a tiny (tiny, tiny) bit.

I second that idea about adjusting the cables in the sockets. When mine had a similar issue post-soldering, that fix worked. If it hasn’t for you, I’ve also heard on this forum somewhere about making sure there isn’t a little grit from your fingertips on the cable itself, since that may affect the integrity of its connection.

Also, I believe I had an issue one time where one of the copper pieces in the cable bent out of place when I put the ribbon into its socket. Maybe check to make sure all the copper leads in the ribbon cable are properly in place and actually going in?

Last thought, one of the cables I’ve soldered needed to be touched up a little while later, even though they looked fine. Perhaps there was a tiny region with a bad joint…I hope this helps!

There actually is a grid of dark red dots behind the logo on the adjustment screen. They’re drawn there on purpose.

I’ve readjusted the display in the slot multiple times, cleaned it, and since they’ve been resoldered, I would like to hope they aren’t the problem

Having fixed them myself, I know that it’s possible for a repair to appear perfect and for the display to test out fine, then start glitching again. All it probably needs is a little more solder and a quick touch of the iron on each wire. Have you asked the person who fixed it originally to give it another go?

I also wouldn’t rule out the LIF socket itself. Besides the “dimpling” problem, it’s possible the contacts themselves are simply not gripping tightly enough, or are a bit corroded. You could try putting a piece of tape along the back side of the end of the cable, to try to make it thicker. You’ll have to be extra careful when inserting it, though. And be sure to also do the “fully in, then pull out slightly” method of seating the cable.

Theres another, much harder to fix possibility. If your cable has a crease in it, like this:

It’s possible for one or more wires to have broken along the crease, due to fatigue. When I do a repair, I always A) check for that problem, and B) put a piece of tape between the display and cable, on the LED side, to take the strain off the cable, like this:

It doesn’t solve the problem if it’s already broken, but it hopefully prevents it from happening if it hasn’t. If your repair guy didn’t do that, you might want to do it yourself.
