HDMI problems, Comcast box and Samsung tv
by Bruins17 - 2/10/08 2:28 AMHey guys,
Hoping someone could help me out with this problem...I bought a brand new 32 inch Samsung LCD yesterday. I decided to go with the HDMI connection.
I have Comcast service at home, with a Motorola DCT3416 I box with Firmware 16.20. The picture is beautiful when it works...however:
The problem: Everytime I turn off my TV and I turn it back on, the screen is just blank. If I go to the back of the cable box and I unplug and plug back the HDMI connection, picture to the TV comes on immediately.
I've played around with all the HDMI settings on the cable box (turn the box off and press menu) and nothing seems to fix this problem.
I shouldn't have to do this everytime I wanna watch TV right???
Thank you for the help in advance.
Bought it yesterday?

There's HDMI and then there's HDMI
by samkh - 2/10/08 8:50 AM In reply to: HDMI problems, Comcast box and Samsung tv by Bruins17Because it implements HDCP, the source and destination may not be handshaking properly (thinks you are trying to steal the content). Did you try powering off the Comcast box when turning off TV and then power both on again?
yeah...
by Bruins17 - 2/10/08 4:33 PM In reply to: There's HDMI and then there's HDMI by samkhi've found that if i power off the box and power it back on, it works the same as if i unplugged the hdmi cord and replugged it back in...the picture comes back up immediately.
but i shouldn't have to do that right? what a pain to have to A. unplug and replug back in the hdmi cable or B. power the box on and off everytime i want to watch tv!
there has to be a fix for this...
I had same problem with my sony kds-xbr150
by brianj112561 - 2/10/08 8:04 PM In reply to: HDMI problems, Comcast box and Samsung tv by Bruins17I had the same problem with my sony.Every once in a while I would turn on my tv and got just a green screen.It's funny that as soon as I bought a new tv xbr2 the problem dissapeared.I believe its a hdmi and communication problem with you box.The only thing you can do is to go back to component video cables until they come up with a fix.
CURIOUS TO KNOW OLD THE SONY KDS-xxXBR150 MODEL IS..........

LOL.

I am just curious...
by stuntman_mike - 2/11/08 9:03 AM In reply to: HDMI problems, Comcast box and Samsung tv by Bruins17when you say you powered off the cable box and then back on again, are you talking about hitting the power button on the remote or doing a power reset by unplugging the box for 10 seconds?
If it is the latter, I can definitely understand how annoying that would be. But if it is just turning the box off when you turn your TV off and then turning both back on, I would not see the big deal in that.
Cable boxes and HDMI can be very funky. I don't have Comcast so I don't know about that box, but maybe they have a newer (or older) box, or one from a different manufacturer, that you might swap with and see if that helps.
If not, then the last option would be to get a different TV which is obviously not the best option.
Call Comcast though and see if they know anything about this issue and to also see if there are other options for boxes.
Good luck
Same Problem
by bill.krueger - 2/12/08 6:12 PM In reply to: I am just curious... by stuntman_mikeI just bought a 19" Samsung LCD TV a few days ago and I'm having the same exact problem! I also have Comcast with the same box. There has to be a solution to this problem, it is really annoying... Anyone else been able to fix this?
Get them to switch out the box
by Bruins17 - 2/18/08 1:41 AM In reply to: Same Problem by bill.kruegerHi Bill,
I had comcast get me one of their new DCH boxes, with firmware 18.34 and that has fixed my problem completely.
Their old DCT boxes with firmware 16.20 was the problem. They had an attitude too when I tried to switch out my box so don't let them get snippy with you! They all try and pretend that the DCT boxes are fine when they in fact know that the 16.20 firmware is crap.
Good luck!
Any other solution...
by Lummer1 - 2/23/08 4:40 PM In reply to: Get them to switch out the box by Bruins17I am experiencing the same issues, I tried a new HDMI cable and I just tried swapping out Comcast cable boxes with the newest model they have, and still no luck. Either the picture just comes in and out or no reception at all.
Really frustrated to think that my 46' Samsung HD LCD tv just gets plain old 480 feed now...
Anyone else with any solutions?
The new box fixed it
by bill.krueger - 2/25/08 7:38 AM In reply to: Get them to switch out the box by Bruins17Thanks Bruins --
I just spent the last week dealing with all the incompetent people at Comcast attempting to get a new DCH-3416 with the 18.34 firmware. I finally went to the service center and got one myself, and when I got it home it was stuck in some ridiculous reboot mode. After going to the service center two more times (the first time they said they didn't have any DCH boxes and tried to tell me the DCT box was fine, like you anticipated). Finally, I got a working DCH-3416 and the problem was indeed solved.
It's sad when we know more about Comcast cable boxes than their employees do....
Box...
by Lummer1 - 2/25/08 4:53 PM In reply to: The new box fixed it by bill.kruegerSo, the cable box actually solved it? I thought I eliminated that possibility by swtiching out two boxes and still no picture. After I switched out new HDMI cables, I just figured it was now my HDMI input for the TV...arghh so frustrating, I simply went back to coax cable. But down the line I guess I will have to try a new cable box again...
Check your firmware
by bill.krueger - 2/25/08 5:01 PM In reply to: Box... by Lummer1Make sure you get the DCH-3416 box, if it is available in your area. On your current cable box, you can check the firmware version. If it is 16.42, it is not new enough to resolve the box.

yeah that's the page i used too...
by Bruins17 - 2/26/08 7:16 PM In reply to: Check your firmware by bill.kruegerHey Bill,
Yeah that page on wikipedia is great...i used that page to realize that the firmware 16.20 was the problem and that the new DCH boxes should solve our problem.
It really is sad that Comcast won't work harder to just phase out the old boxes. They've had the DCH boxes since like June of last year. I really don't understand their business model.
Why keep unhappy customers in the dark when you have a newer and better product? And then treating us like we are idiots and that we don't know what we are talking about?
Very frustrating to say the least.
I have a DCH3416 still exhibits same problem
by blhahn00 - 3/14/08 2:16 PM In reply to: yeah that's the page i used too... by Bruins17I just swapped out my DCT3416 for the newer DCH3416 after mine started giving me troubles this past Sunday. Not sure what the firmware version is (will check tonight), but I still have the same problem. I will more than likely switch back to Component.
