HDMI Connection w/ Time Warner's Scientific Atlantic 4250HDC

by Bennett Parker / November 8, 2007 7:42 AM PST

Thanks in advance for any help with my problem.

I have a brand new Panasonic 50PZ700U and have Time Warner's 4250 HDC STB. For whatever reason, the HDMI signal keeps going out and T-W's only solution is connecting with Component cables, which although works fine, is not what I wanted to do. When the HDMI cable is hooked up to the TV and the box is re-booted, all I get is a blank screen. I have taken 2 boxes back thinking that it is a bad box, and I have also replaced the HDMI cord (actually Circuit City replaced at no charge after the T-W told me it had to be the HDMI cord, since everything else on box checks out

Any suggestions on why I might be getting only a blank screen when hooked up to HDMI? It worked when we first had it installed, but nothing now.

Thanks again for any help.

How long are you waiting?
by 808IUFan / November 8, 2007 8:52 AM PST

It takes approximately 5-7 minutes for an OCAP box (yours is) to reboot. You will probably see L-13, L-12, etc until you get to L-1 and then the time will display. You should NOT touch the box or try to turn it on until you see the countdown go all the way down and the time display. You can turn your TV on and you will see the same display.

just a new TV?
by 808IUFan / November 8, 2007 9:41 AM PST

Have you ever seen a picture? This is a location you had before and just a new TV? How is the box hooked to the TV? Doesnt sound like you have the right source chosen if you have no picture at all.

I agree that it sounds like I had the wrong input selected.....The T-W box is attached to HDMI1 and that is the input that I have chosen.....adn yes; it did work for a while ...but nothing now...

Do you ever see the correct time on the box? If you hook the cable directly to the TV do you get a picture?

I would make sure you have the correct source chosen on the TV. If the correct time is there and the box is on, try changing between a non HD channel and a HD one and see if the 480, 720, 1080 indicator above the time changes. If it does, the box is working fine. You are not seeing the pic on the TV cause you have the wrong source hooked to the TV or Chosen.

I could be wrong about this...
by stuntman_mike / November 9, 2007 3:11 AM PST

but I don't think I am. I think that it is the box.

My brother works for Time Warner, and he told me about their new boxes and how they have all kinds of issues when used through HDMI. From issues like yours, to the TV being displayed in normal aspect ratio (4:3) even on HD broadcasts, and having the options to change aspect ratio say that that action is not supported when you change it.

He told me that it will work fine through component, just like in your case, but I would not be happy with that anymore than you.

I had told him that I wanted one of the new boxes, just because it was new, and he told me not to get one until they work the kinks out.

Like I said, I could be wrong, but I don't think I am. Time Warner is also aware of this issue as all of the techs have made them aware. Hopefully when enough people complain about not being able to watch via HDMI they will address it.

Sorry I couldn't be more help, but I think your best bet is to get your hands on a Scientific HD3000.

Good luck

I work for TW tho
by 808IUFan / November 9, 2007 6:46 AM PST

I have 3 of issues..all HDMI. What we need to know is if there is signal at that location and whether it is good. Sometimes the time will display but if the signal isnt strong enough the box will not boot up. Have been going back and forth with this issue but it is hard to cover everything like this. Did we ever find out if the cable wire is hooked directly to the TV if it has a picture? Has cable ever worked at this location. Did he split the cable and run it a long distance to where this box is?

unplug the cable from the box and hook it straght to the TV to make sure the coax cable and tip is working.

if it works with compnent the box should be working fine, it an HDMI problem, you might try a better HDMI cable, you never said what name brand you had.

TW has found
by 808IUFan / November 10, 2007 1:32 AM PST

That a lot of new TVs have a needed firmware update to make them work. After you try a different HDMI, make sure its no more than 6 ft, try to call the TV manufacturer to see if there is a firmware update. If their is, they will mail you a device to install it.

HDMI Cable
by johnnyblack87 / November 10, 2007 7:11 AM PST

Try a higher end cable. If that doesn't fix it, stick with the cable, it'll be better in the long run anyways. The tv itself has settings labeled "EZ Sync." Check those and see if there's anything conflicting. If that doesn't work, find some cheap component cables and hook both the HDMI and component up. Reboot completely, and then switch back and forth b/t HDMI1 and whichever component input you use. If the component is showing, and the HDMI is not, AND you're absolutely positive that it is NOT the box (test another HDMI source on the TV, or pull a box from another room and test that one), take the TV back where you got it, see if they can repair or replace that TV.

The problem I am having is that it won't show the non HD channels using the HDMI.. just the HD channels come through. My one downstairs which is the DVR works on all channels but not this box. Anyone run across this?
