Based on title, before 2019 I bought HDMI ports for slim / pro with serials. Install them, test them, jiggle them with no issues. Now since 2019 anything I buy for slims / pros result in cut outs when jiggling. I am going crazy. I have cleaned them with IPA and contact cleaner resolving the issue for only 20 minutes and it happens again. I have purchased from ali express and trusted sellers, still same BS. Maybe 1 out of 4 will not show issue. I think its the result of junk sealer on port pins??? Anyone see this issue???
