The lcd on the kpa 500 shows onlty test pattrrn except when I upgraded the firmware to version 1.54 from ver 1.38 today during the upgrade the lcu showed Mcu Load like it is suposed to do. When done the unit restarted and the damn test pattern is back all the time.
Prior to upgrading thr firmware I suspected the led driver chip U6 PCF8576DT to be at fault since it has the power on reset function which I thought was causing the test pattern, now not so much. Anyway it works 100% otherwise just have to monitor it from the pc port. All other front panel stuff works I suspect the buttons for the menu pwr current and temp work also but I cant tell since the lcd only shows test pattern. Looking for Don or Wayne to comment I put in an email to the mothership yesterday with few details but today much happier I dont have a brick.
