DLP Experts: have you noticed this before?

I would like to ask all DLP experts in the forum who have used the technology for a long time or who know a lot about the technology to help me understand a issue I noticed only once in my new PJ.

I have posted this in the other forum as well. But since this is more related to the technology I thought of posting it here as well to have a better chance of response.

I have an Infocus IN80 1080p DLP and it is an awesome machine. Absolutely loving it. I have clocked up around 68 hrs so far on it.

Last night, when I turned it on with the Blu Ray player, I saw some short vertical stripes at the lower half of the right hand side of the screen. I thought that there must be a loose connection or sync issue so I pressed the auto image button and then the bands covered the entire right hand of the screen from top to bottom.

I then connected my laptop via HDMI to see if it is there in another source and I saw the same. I looked at the Internet but couldn't see any problem or issue mentioned anywhere. I took a few handheld screenshots to show the issue (see below). I have already emailed Infocus about this but thought of posting here to see if anyone has experienced this before.

I restarted the PJ after resetting all cables and connections and it was all fine from then.

What I would like to know is
1. have anyone seen or experienced this before? or know why it can happen?
2. Is it related to loose connections (i remember the HDMI cable wall pulled by my friend's kid before this and the PJ was off that time)
3. Is it an early indication of any problem?

Appreciate your thoughts on this. probably it is just a connection issue but wanted to clarify if there is something bigger than I am thinking.

Screenshots of the problem

Thanks to all of you who responded so far. Expecting a call from Infocus soon.

On restarting the problem cleared up. Will check again today.

Meanwhile look forward to what others have to say.

The HDMI cable pulled by the kid was the Blu ray player end and not the PJ end. The player and the Pj is separated 7 mtrs apart and there is some slack as well. I just thought if a improper connection could casue this, But when I saw the same thing on the laptop I was convinced it is not the connection and Georgeb's and f300v10's post are convincing as well. Infocus appears to be very good in this part and they are swapping a new Unit soon

Thanks to all who responded. Infocus did a fantastic service and they just replaced my unit with a brand new one. Great service.

Thanks to GeorgeB whose response is now with Infocus and they will review the fault.

On a whole this is a rare issue and I have noticed it only once. Now I have a new IN80. More movies...

Cheers
