My 37pfl7605H12 brings from time to time "no signal" on all HDMI connectors. Most after using NetTV.

Only 10 minutes of power off (cable of the wall) brings me the picture back.

My 6 year old Grundig LCD brings a picture over HDMI. The 37pfl7605H12 brings only "no signal". So, my Technistar S1+ has no error.

I think this is a HDMI protocoll error.

Please fix it in the next firmware update.

Or is this a warranty case?
