Black screen - audio works - hp logo on start - then goes black

Suddenly when watching - the screen went black. We had paused the cable DVR & this happend when resuming play. It is possible that our cable remote may have been bumped at the time. The audio works. I can change inputs - but of course cannot see what is on the screen. Something similar happened several years ago & we somehow reset the TV & it worked. I have tried the recommended HP reset (unplug everything / hold power button for 5 seconds - then plug in) & it does nothing. Once when experimenting - I saw a 'wake up' msg on the screen.

It is either the power supply or the backlight inverter board finally failed. You will need to do some voltages checking inside, also see if you can see any bad caps in the power supply.

No picture on intermittent basis -

If you have tried using different input devices, looked for loose contacts

Trying to dub from dvr to vhs vcr

Is L2 for composite video (yellow) or S-Video? Try watching a video on L2 with the composite video plugged into the back of your TV, if it works, then do the same with the DVR, if that works, then run the DVR composite video into a receiver, then the L2 from the VCR to the video out on your receiver. It's possible that the VCR won't record anything that isn't an applified signal. That's what the receiver does.

HDTV goes blank when connected to Fios HD-DVR or Fios DTV recvr.

If you can first connect the Fios box via component and that will rectify the issue and still allow HD. HDMI is funny, if there is anykind of communication issues between the TV or the Fios box you see what happens. You might also call Samsung to see if there is ANY firmware/software updated for your TV specifically to fix such an issue with the Fios/Mortorola connection. If there isn't then the issue is the cable box since the TV works ok on HDMI with other devices.
