Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

1 Answer

DVI / HDMI problem

I recently connected my TV (Samsung HCN4226W) to my cable box (Scientific Atlanta-Explorer 8300HD)using a CVI/HDMI cable and it works fine until you shut it off and turn it back on. When the set comes back on a messahe displays "DVI signal can not be found". While the set is on, I unplug the 24 pin DVI connector form the back of the TV and plug it back in and the set works fine. It appears that when the set first comes on, it doesn't see the DVI signal until it is unpluged and repluged. I verified all of the connections and they are correct. Is there a programing step that I missed? Thanks for your help jegunz

This problem is almost certainly on the 8300HD side of your setup. URL for the 8300HD, just in case you need it: --> Dittos for the TV, just in case: --> You're using the HDMI-to-DVI cable to connect, and I see that the manual warns on the bottom of page 11 that some DVI connected HDTVs are incompatible to the signals that are output by the HDMI interface. First thing to try - when you change the settings in the 8300HD, in the "General Settings > Audio", see if you have this problem with all of the possible selections, or if it's only with the "Dolby Digital" setting. Since the HDMI also contains the audio signal, it may be interfering with the DVI recognition in the TV. OR - See if you still have this problem when turning the TV on first, then the 8300HD. Or vice-versa. The power-on order of the two devices may make a difference. OR - With the TV on and with the 8300HD off, press the GUIDE and INFO buttons at the same time. Using the on-screen menu, verify that it is set to HD mode. Press the POWER button on the 8300HD when finished. OR - Replace the HDMI-to-DVI cable with a PrPbY/V component cable, available at Radio Shack, Best Buy and other electronics stores. One of these options should solve the problem. If not, you'll have to start sending e-mails to Sci-Atl and Samsung. Hope this helps! ;)

How do I connect a Sony DVD DVP-SR210P to a Scientific Atlanta Explorer 4240 HDC and a Sylvania TV C320SLX?

I am not sure you can connect your DVD player to your cable box. You should be able to connect both your cable box and DVD player to your TV set with two HDMI cables. This link is a pdf_usecares file of the TV manual that shows how to hook up your dad and cable box.

Hope this helps.

HDMI cable hooked up, now CLOSED CAPTIONING is stuck on!

It has got to be the box. I would try to contact Scientific Atlanta if any way possible. The TV doesn't choose what inputs it shows CC.In other words, it would show it on all Inputs if it was the TV. Good luck and Thanks

"cable box to tv is hdmi cable"

Everything I've read on the web says cable box to tv connection must also use component (rgb) cables. The error is coming from the cable box (STB). All the Scientific Atlanta (SA) cable boxes seem have this Digital Rights Management (DRM) bug and the only way to be totally rid of the error is to replace the digital connection from box to the TV with an analog connection.

Cable box remote doesn't work when tv is turned on.

I am having this same problem with our Mitsubishi LCD Flat Panel TV, Model LT-46246 ans our Scientific Atlanta remote cable box, same model as yours. We cannot use the remote at all to change the channel. I called Mitsubishi and they said they have never heard of this. I find this incredibly hard to believe. Time Warner, our cable provider says that it is not the box because it works when not hooked up to the TV. What a pain. I would love to hear if anyone else is having this problem or has a fix for it.

I have the following hardware: Marantz SR-4003 Receiver, Samsung LN52A650 HD TV, Samsung BDP-1500 Blu-Ray player, Scientific Atlanta Explorer 8300HD cable box, two Paradigm Millenia 20 LCR Bookshelf...

Remove the HDMI cable (out) to the speakers from the receiver.
Connect regular speaker wire from the receiver to the speakers.
Of course, remove the (now extra) HDMI cable from the tv.
That will remove the loop.

HDMI->DVI cable won't work

Are you using a HDMI to DVI cable or are you using a HDMI to DVI adapter? Sometimes, though not on all products you have to go into the menu and select which out put your using for each source and whats going through it. You might need to go into your dvd player menu and tell it not to try to run audio through the cable. That way it's not trying to force a signal through the cable that cant be accepted by the TV. That might possible solve your problem for the DVD player. Let me know if it works
