it's a plasma TV, not lcd.
it's a PN50B850Y1F
firmware is 1013, apparently the latest on the samsung site (although from 2009).
i'm having a chronic problem with my samusung lcd monitor and several sony blu-ray players-
in the middle of streaming netflix via wireless connection from cable modem, i get a black screen with " no signal" displayed. if i unplug the HDMI cable, it says "check cable" instead. it doesn't happen playing blu ray discs, or the cable box, or when i watch the same netflix stream on a computer monitor at the same moment. i thought it was the blue ray player so i replaced it. no better with the new one.
it seems like an HDMI handshake problem, and very frustrating.
Any fixes out there??? it makes it unusable.
