Has anyone had any problems with vibration and their TV monitors? Specifically direct views? I have a Sony KV-34XBR800 widescreen direct view monitor with a Def Tech CLR2002 center channel spkr sitting on top of it. During loud passages at reference level SPL (80 dB) I can see interference (look like dark “waves” on the screen) in bright areas of picture i.e. sky. It is very apparent on the CA: Full Throttle trailer, Tears of the Sun during the bombing attack and the riot scenes in Dark Blue, for example. I placed some Monster Cable Vibration dampers under the speaker but it did little to change the situation. Is this normal for direct view TVs, or is it something that I should have checked by a Sony tech under warranty? I had no such problems with my previous 41” Sony RPTV, but on that set the speaker and CRTs are separated by a few feet. I want to avoid having to build a shelf to place the speaker on behind the TV for a # of reasons, primarily speaker height will be incorrect, blocking of my backlight setup, and the extreme depth of the TV.
