There are multiple posts on this forum of these LCD’s crapping out. Some people recommend trying to clean and reseat the connectors. Some people say you need to replace the LCD or the ribbon cable.
I can not find any replacement parts for this online so far, and I definitely do not want to replace the entire cluster just for this small LCD.
I emailed some guy in one of the other posts that said he repairs these asking for a quote, but I don’t feel 100% comfortable sending money to some random guy on a forum with promises that he will fix it.
