I'm looking into it but you might want to see if our Service Center is familiar with that symptom. I haven't heard of this before. The phone number is 800-SAMSUNG. Let me know if that works and I'll let you know if I hear anything from my side.
Having just received my new LCD TV, very happy with the picture quality but am having problems with the Menu box intermittently flashing and beeping each time. I seem to be able to resolve this by unplugging at the mains and re-starting but this is hardly practical. I'm not sure if this is connected to the number of items connected - DVD; VCR; Cable set-top box; Broadband modem. Any assistance greatly appreciated or it will be going back to where it came from!
