Hey guys.

After having watched half a dozen movies on my new marquee, a "flickering" of the picture is starting to occur. sometimes the picture goes completely black for a second this can happen 10 times within 30 seconds or 30 minutes plus the picture afterwards look kind of disturbed. primaryly these 3 observations.
-the entire picture sort of shakes now and then
-The entire picture sometimes shifts from a normal colorshade to a sligth lighter colorshade
Another observation Ive made is the blackshade. Its like the smoothness of the blackshade is not there. Its like the shades of black are divided into to blocks and the picture shows the 2 shades divided like that.

Im getting pretty annoyed with my marquee. Any suggestions whats wrong?

When that problem comes, try hit # key on marquees remote and see if internal testpatterns are ok. If they are, there can be something wrong with "digital" connection between VP-50 - Hdmi input card. Probably groundloops, that can mess up hdmi signalchain.

Then trye put VP-50 testpatterns on and if those are not ok then start unplug sources from VP-50. Usually groungloop is formed between earthed components. Many times culprit is source that has antenna connection ( earth of antenna network is not at same potential as power outlets are)

it could be the CLM/DPB chips need cleaning as well, this should be the FIRST thing any new marquee owner should do. Then also clean the daughter board on the HDM.

Can you define "cleaning"? Is there a thread that describes this process?

And here I thought the FIRST step was checking/fixing the LVPS filament. Or is that the FIRST FIRST step? Smile

No no no. The first first step is to curse at how heavy they are and how much your back hurts after you move it. THEN you move onto the other stuff.
