Dark Screen Not Dark KNIGHT !

**subshop** · 20.07.2012, 17:56

I was checking my tank's parameters yesterday and I noticed my ALK, Mg, and Ca levels were all lower than I usually keep them. As I was checking my dosing unit I noticed the screen on my PIII was dark. All the buttons were still illuminated but the screen is dark. I disconnected the power supply, which was very hot, and then plugged the unit in again and it started as normal. Within a minute or so the screen went dark again. Any suggestions ... Thank You in advance for your help, Neil.

Looks like the power supply is defective.

I thought so too. But because the buttons are still illuminated, I thought it may be internal ! Wonder if I could use a generic power supply to power the unit and see if problem persists ? Any thoughts ...

If the screen is turning on and off it sounds like the front board or the DCDC converter on the main board, please contact your local distributor for repair.

If you can get a generic power suppy this will speed up Matthias diagnosis or use the power supply from a doser if you have one. Let me know by email, we have PSU's here.
