Sony and comcast HDMI Problem

ogersbronco · 10-06-2006, 11:50 AM

About a week ago I bought a sony KDL-40S2000. The Tv works fine until
I tried to hook in up to the Comcast dvr model #dct3412. The problem I

am having is that I when I switch between an HD channel and a SD
channel the Tv goes blank. If I my TV off then on again it will show
the channel. I can switch between a HD channel to another HD channel
and it is fine but if I try to go to a SD channel the screen goes
blank. I am using a HDMI cord. I called sony and Comcast and both of
them don't know what to do and have never heard of this problem. I
tried component video cords it will work fine but I want to use the
HDMI cord because my component video slots are all full

I am on box number two from Comcast. And I had the problem with the
first box and now the second box.

Please Help

My only suggestion is to get their other HD DVR box that has DVI and not HDMI. Im assuming you probably have a DVI port as well as HDMI. At least my tv does. But honestly, sounds like theirs a compatibility issue between the box and your tv. Your prolly farked. Or its time to get a DVD player that does hdmi and use the componant slot on your comcast box. I have one tv with componant and one with HDMI. You cant tell the difference in picture quality. Both look great.

no I only have a HDMI port in the back of the tv

you just get the tv? Take that shit back dude if sony cant help you. I would. Unless you want to look into dish networks or dtv. I dont think theres anything you can do to fix this. Have you tried another HDMI cable for shits and giggles? you really dont have too many options to try here if both the manufacturer and the cable company are telling u they dont know. Swap out cables, swap out the box, which you already did.

no I am going out tonight get get some cables becuase my dad saw mine and he brought one. So I will try that and see if that helps. I called sony and they said it was comcast's problem and comcast said it was sony's problem. The HDMI cable works fine with my computer hook up.

davecramer74 · 10-06-2006, 12:12 PM

ya i dont think its the cable, but might as well exhaust all you can. You tinker with different display combinations at all? Like zoom, etc?

ogersbronco · 10-06-2006, 12:14 PM

I can't figure out how to change the setting on the cable box. I read somee threads but they tell me to do change the setteing but I can;t find the settings to change.

davecramer74 · 10-06-2006, 12:18 PM

i think before you turn the box on, you click setup if i recall. Ill post back here late on when i get home and let u know. Do you get the screen where its just grey background and the words are in black? or u just going from the normal setup menu when the box on?

ogersbronco · 10-06-2006, 12:19 PM

ok i will try messing around with it after I get home from work

Which cable box do you have? I have the SA 8300HD for Cablevision, but my buddy with Comcast has the same box. If this is the one, you can push up on the "Settings" button on the remote twice to enter the "advanced" settings menu. There might be something in there that needs to be set.

I have a motorola dct 3412 from comcast.

davecramer74 · 10-06-2006, 12:48 PM

he's got the motorolla

davecramer74 · 10-06-2006, 08:26 PM

hey i just got home, i have the 6412, not the 34, have you asked them for one of these? Or does it depend on where you live for what you get?

ogersbronco · 10-06-2006, 10:17 PM

I found out how to change my setting. I started changing things. I found out that if I change the cable box output from HDMI to DVI it will work fine but the picture is not as clear. So I don't really knows what that means but hopefully someone does. So how do I get the HDMI to work.

ogersbronco · 10-09-2006, 02:56 PM

I also had my computer hook up through a DVI to HDMI cord. Do you think that may have cause the problem I am having with my TV??
