just switched TV brands, now getting DUI message flashing on STB....

Message 1 of 7

I use a hdmi cable for my non DVR STB, and i just switched from a Vizio 780p to a Olevia 1080i Tv. It works fine, but when the STB is off, a DUI error message constantly flashes on the STB . When you unplug the HDMI from the tv or the STB, it immediatley stops.

Resetting  the STB or HDMI settings on the box will make it go away for  a few minutes then it returns.

I assume this is from some lack of synchronization between the TV HDMI and the STB and I can use component cables instead, but I would prefer to use HDMI and not have the error message constantly flashing as it is very annoying.

 

Has anyone else experienced a similar problem or know any ways to get rid of this? Thanks!

Which model number of STB are you using?

 

 

If you are using a 7100 or a 7216, this is an error with the internal card on the stb. it needs to be resync'd. Call Verizon tech support and ask them to initialize the box with a cable card reload. They will know what this means (or at least they should). Once the internal card is re-sync'd it should stop with the DUI

Error exists between keyboard and chair.

Had the same problem with mine after they upgraded the channel guide.  First, the set-top box kept rebooting itself.  They replaced the box with a new one.  Now, when I turn off the TV the set-top box alternates between dUI and EF01 but doesn't reboot.  In speaking with tech support, this is a known problem and they are working on fixing it, but it likely won't be until after the holiday.

it is an HDCP handshake issue. Try a different port on your TV or receiver, and if that doesn't work the only known permenant fix is to switch to component cables. they are also HD 1080p rated cables and you should notice little to no difference in pic quality.
