RRF vs PanelDue compatibility?

@tgarr said in RRF vs PanelDue compatibility?:

Ok, I guess I'll try to return it.

The only other clue I can offer is that if I just plug in the 4 wire I get a white screen, if I power on and then plug in the ribbon cable I can reliably get the flickering.

Please check that there isn't a solder bridge between pins of the ribbon cable connector on the PanelDue.

@dc42

I don't see any bridging of solder:

Is there anything else I can do short of trying to get a return or exchange? This thing is effectively brand new (it did sit in the box for a month before I got around to trying it).

When and where was it purchased?

@Phaedrux

I had to look it up, Covid time flies, I guess it was more like 2 months sitting in the box.

July 30th through Printed Solid.

Please contact your reseller and request a warranty exchange. Include a link to this thread as authorization.

@Phaedrux Thanks.

Is there anything else I should / could try to make sure it's not the duet2 board first?

Phaedrux · 29 Sept 2020, 02:20

Not that I can think of that hasn't already been tried. Unless @dc42 has any other suggestions.

If the voltage at the PanelDue power input pins on the 4-way connector is a steady 4.98V even when the display is flashing white then the fault lies in the PanelDue.

My guess is a badly-soldered diode DA2 or inductor LA1 (or just possibly LA1 is the wrong component). If you wish, you could check that by measuring the voltage between each end of LA1 and ground. Both places should be steady at about 4.5V.

@dc42 Before I do anything stupid...(I'm a mechanical engineer not a sparky), which side of those components should I check on?

I'd assume the side opposite of the 4 wire connector, is that correct?

As you are not sure, I suggest you just ask for a warranty exchange.

@dc42 FYI the new PanelDue got here today, I plugged it in and it worked, so good call there. Thanks.
