  Kent.  I happen to be here at work where we have Five 32" flat screen monitors.

  I tuned to 144.390 on my Yaesu VX-150 and ran it by each.  No signal interference.  They are different brands and models with the oldest being 6 year old Plasma Sony units and the newest being Winbook and Sceptre.  

  If you are still under warranty I'd get a tech out there.  They will try to pull Part 15 out on you but you hit back with Part 97.  What would they have to do if this was your neighbors set under warranty and you made an FCC complaint about it?  Last resort is to actually make that complaint yourself.

  Sweep the set with a service monitor if you have one and note all the other frequencies it radiates.

  Good luck
