Anyone have any ideas what is happening? When tuned to DAVE channel 19 the picture momentarily blinks every minute or so, apparently at random.
ONLY ON DAVE. All other channels inc Dave+ are perfect. The box is an old-ish DTR-2100. I have tried cutting down the signal strength, which is otherwise 100% (from a home distributor amp). The lowest I can get with 20db attenuation is around 62%, at which point "signal quality" starts to drop, but all channels still work as before, including Blinking Dave.
BTW he (Dave) does not blink if connected to the TV tuner directly... HELP
I have seen the problem reported before.
