Has anyone noticed a problem with what appears to be waves as the camera pans/scan vertically in a scene during a HD broadcast---not there or noticeable with SD broadcast. Could this be a convergence problem or some other manual adjustment that I can make to my set OR would it require a "specialist" to correct?

I have a Mits 55807(2mos old) and a Hughes HIRD-86 STB (2wks old)----actually didnt notice it until I got the STB and could receive HD broadcast. Mainly just an annoyance because the picture is terrific otherwise

HDBob,

I have a Mits 55905, and just noticed something similar the other night while watching The Patriot on HD-HBO (Dish, sat 61.5). It was evident at times during the movie, and very obvious during the scrolling credits. Looked like a ripple about a 1/10 of the way up the screen, all the way across.


As I've been watching HD for nearly a year now and never noticed this on any other program, I tend to think this was an anomaly originating from the transfer or something in the HBO/Dish pipeline.

HDBob,


The problem you describe sounds like a problem with the geometry of the set. This is assuming that you see the "wave" on all HD material, and not only on a single movie like davestill describes. The set has seperate memory for each mode, which explains why you are only seeing the problem in the HD mode. Setting the geometry accurately is a process described in the service manual, and is generally performed by a professional (although it usually doesn't require any special equipment so it could be attempted by a brave owner equipped with a service manual). After setting the geometry, the base convergence will also need to be redone.
