when I use any of the video inputs the screen will flash completely black for a second and then go back to normal. what could cause this? the only input in use that I haven't tried is the DVD input.

I have a toshiba 57hx93.

Could you give us a tad more info? What is the source, SAT-Composite or SAT-S-video etc....... Are you using the internal OTA or Cable tuners?

How are you switching? Pressing the 'input' button then selecting 1 or 2?

I checked my set and it does go to black for just an instant when I switch inputs. Video 1 or 2 and HD1 or HD2.

Not sure if you are having a problem

ok, here goes:

I have an external STB - motorola 5100

it is connected via coax from the box to my vcr then to ant1 on the tv.
it is also connected via the component video as well. this goes directly to the tv, not thru a reciever.

my reciever is plugged into Video 1. this is where my vcr connects to the tv. my vcr is plugged into the reciever.
the STB is connected to the Colorstrem HD2 input.

when I switch I just select input and go to #5 for hd or #0 for cable. the flash is present on these inputs as well as the input that the vcr comes into.

as far as I can tell, this is not present on my SAT system which is also routed thru my reciever and comes into Video 1 as well. - the same as the vcr.

It seems like this is only present with my cable system and anything that is connected to it.

I also have a vcr which is used for recording that just has the cable go directly into it(via a splitter) and it does it on this as well.

if I record something this flash does not record. It can happen during playback but if I rewind it will not be there.

this black flash just comes and goes all the time, not just when I change inputs. I can just be sitting here watching a show and the screen will just go black for a second then return to normal.

if you need more info please let me know.

The only "black dropouts" I see are on the HD channels. They last a second or so and the image comes back. Not sure if this is what you're talking about since it sounds as though you get it from SD material too.

I seem to be getting it on all channels. could this be a weak signal coming thru my main cable line?

[chrishicks]

could I also have a bad cable, splitter or something?
