Flickering tablet screen has me stumped after a basic repair
I'm trying to fix an old tablet where the screen keeps flickering. I opened it up and made sure the ribbon cable was connected tight, but no luck. I've even tried a different battery in case it was power related, but the problem persists. Does anyone have ideas on what else to check before I give up?

My neighbor's Kindle Fire was doing that crazy flicker thing after I replaced the battery. I swear, cleaning the connectors with alcohol did nothing at first, and I was ready to toss it. Then I read online about gently rubbing the gold pins on the cable with a white eraser, which sounds weird but it worked. It took a few tries and I had to blow out all the eraser dust, but the screen finally stayed solid. Honestly, sometimes it's just about getting all the tiny bits of grime off, even if you can't see them. Don't give up yet, try the eraser trick on both the cable and the board.

Mentioned cleaning the connector pins with isopropyl alcohol. Did you check the ribbon cable for any physical damage, like small tears or bent pins? A close look under a bright light can reveal issues you might miss. Also, make sure the connector area was completely dry after cleaning before you plugged it back in.

Had the same flickering nightmare with an old galaxy tab. What finally fixed it was carefully cleaning the actual connector pins on the board (not just the cable) with a tiny bit of isopropyl alcohol on a q-tip. A tiny bit of corrosion or dust in there can cause havoc. Reseated the cable a bunch after that, and somehow the third try it just decided to work, go figure.
