Messed around with my broken DTVPal DVR again tonight before unplugging it for the night and here is what I saw tonight.
Plugged it in, then I turned it on, the red and green light stayed on for about 8 seconds and then went off. The HD then started spinning.
Eventually the green light came back on, but I never got any image or sound from the HDTV. Strangely, I am able to turn the green light off and on with the remote. As far as I can tell, the HD is spinning all the time as it usually is.
Almost seems like the unit is working but there is something wrong with the units HDMI output. I know the HDTVs HDMI input is fine since I already tested that with another DVDPal DVR. Gonna try the other audio/video connections tomorrow and see if they work.
Thanks again to everyone who has helped me with suggestions via this thread and via PMs.
