Vertical line on TV with brand new HK AVR354 receiver
I've got a brand new Harman-Kardon AVR354 receiver. 10-year-old, or so, CRT TV. Seeing a single translucent vertical line, though it moves around to various positions on the TV. Sometimes it goes away, it's rarely there at receiver power-on (from cold), but appears about 2-5 minutes after. It's there regardless of signal source (I tried cable box, Wii, DVD player, etc). Also tried a 2nd, similar TV (older), different cables (using S-Video and/or composite) with the same result.
Is this receiver busted?
