SunSynk Touch screen
My Touchscreen panel does not seem to respond to touch commands - seemed to start when I plugged in the WIFI dongle so i assumed that it was expected behaviour but now I am not so sure. the up/down/return keys still do some screen changes but with no cursor or anything it's guesswork.
Any suggestions on how to correct this?

Try unplugging your WiFi dongle to see if you screen works again. If so check the dongle connector plus inverter plug and give them a clean could be some dirt in the connector or a faulty dongle. You can always raise a call with sunsynk support
