Title: LCD interference in display after new touchscreen install...HELP!!!
Post by: theycallmewayno on May 03, 2021, 02:19:40 PM

Please help!!! Our upright game king had a bad touch. So I ordered a touch and decided to be adventurous and make the install. After staying on the issue all day yesterday until 2a.m., I have the touch working correctly. (Thank you to a previous post regarding converting molex to NOVRAM!) What I noticed though immediately after removal of old touch and first of many new touch tests, our LCD had what appears to be interference on the right side (if your facing it) in approx 2-3 inch strip vertically. I added pictures for clarity. So thinking it was new touch, I removed touch attached to its metal frame and just mounted lcd to the mount and powered on. Still same issue. I have looked at all external grounds etc. This was not happening before removing old touch. I feel like it's an internal ground issue inside lcd? Any ideas? It seems so odd to me that it is on the same side as the backlight power controller. I added those pics too for reference. Thank you for your time!

SOLVED! See pictures! The ribbon wasn't attaching at top correctly. When I replaced Touch I obviously loosened this.
Hopefully if y'all ever run across this issue, it will help you diagnose!
