We (a nature-lovers club) have five mobile trolleys each incorporating an HD1020 connected to an ELO ET2243L monitor via HDMI with USB for the touchscreen. The content, mainly JPGs and MP3s, is loaded by SD-card. One of our trolleys is reported to occasionally show "colored stripes" instead of the presentation. Powering off and on fixes it but of course we want a proper solution. The equipment is less than a year old so under guarantee.
I have not yet seen the problem, nor has anyone made a photograph, but I talked to some who have seen it and they talk of "blockiness" which might suggest a JPG artefact. For now I make no assumptions and suspect any of the HD1020, display, cables and SD-card. I swapped the HD1020 with our development rig which I have at home, it has now run for two days without problems and I have heard no reports of problems at the site.
Does anyone have any troubleshooting tips?
