"Searching for Signal" with HDMI cable When I connect my HD cable box to the TV with an HDMI cable, when switching HD channels, I get a "searching for signal" message on the TV. Takes a while to settle in on the signal and produce the picture. When I use the component cables instead, I don't have this problem. Anyone know what the issue is?

Thanks for your reply. It happens to us when we go from non HD to HD and from HD to HD. Very annoying. We've dropped back to using the component cables, but I sure would like to use the HDMI. I was hesitant about complaining to Samsung, since our cable is so sketchy, but now I think I will.

Just got off the phone with Samsung. They directed me to get DIRECTV to change out the receiver. I will let you know.

my new samsung was working perfectly last night and now has a "check signal cable" notice. The cable box is showing 480p; how do I change it to 1080i?

Rum,Thanks for the info! It solves all the issues with HDMI input and flashing delays when changing channels. Simple solution for a big problem with Hi-Tech.

I'm on my second cable box. Same problem on both, although the second box does get a better signal for the non-HD stations. Let me know how it goes.

Short answer: NoLong answer:Because this cable does not actually convert the signal from analog to digital, if you did hook up your box with this cable to the TV the signal received by the TV in the HDMI port it wouldn't understand, and would not display anything. (The output of your box being RCA outputs an analog signal, while HDMI is a digital signal.) Hope this helps.

I know exactly what the issue is. There is a setting on your cable box/sat box where you tell it what resolutions your TV can support. Some cable boxes allow you to pick multiple choices (e.g., 480p, 720p, _and_ 1080i at the same time). What happens in this case is that the cable box will automatically output the signal at the native resolution of the broadcast, provided it is on your selected list. This usually results in the cleanest picture, but of course it causes your TV to have to change resolution modes to match the input every time you change from a channel with one resolution to a channel with another resolution. On my Samsung DLP, I chose to put up with this constant switching because it resulted in the cleanest standard-def picture (my cable box sucks and upconverting SD signals internally). However, if it bugs you, just set your cable box HDTV menu such that your TV only supports 1080i. The result will be that the cable box will internally upconvert all broadcasts to 1080i prior to sending it to your TV, and your TV will no longer have to switch modes all the time. Hope this helps!

Tom, Like you, have a Samsung HD cable box from TW. Connected HDMI to my Pioneer Plasma. Problem I am having is when changing HD channels picture is scrambling for about 5-10 secs before coming in. Analog stations change without a problem, just in HD. I switched out the box twice, same problem. Had a techinician come over, he switched out the box again, same problem. Put the component connection and works fine. Tells me it's the monitor. Pioneer says that's ridiculous, it's the cable box. I have been reading numerous threads about this problem. It's the TW cable box, it does not have the proper software to support HDMI. You have to call TW up and complain and see if they will fix the problem. R

That happened To us and we had to use an hdmi cable and it fixed the issue. We we used a cord connect the cable box to the TV instead of the hdmi, we had that issue. Hope that helps!

Thanks! That makes sense. I did get a message that said something about HDCP. Can you recommend any HDMI cables that are HDCP compatible? I was trying to avoid spending a ton of money on one, but maybe I just have to. I also read on avsforum about firmware updates, etc. I guess I'll try a new cable before contacting Samsung.

I'm sorry, I've only tried HDMI, but that works fine. Can you try that connection, just to your tv temporarily to verify everything is working?

You need the cable to get your cable box connected to your TV for the best picture quality if you subscribe to High Definition channels. A regular cable can also be used to connect your TV to your cable provider. You can use the HDMI to connect other things like a DVD player or Video Games consoles. Hope this helps!

To the best of my knowledge HDMI cables should be backwards compatible, it'd be weird if it wasn't. Is everything else plugged in and connected properly, right TV input etc...Do you have any other HDMI cables to try out?

you probably have component cables hooking it up from your cable box. Just get a $10 HDMI cable and problem solved. The component cable signal is too close to the amplifier on the TV. That signal is much slower than HDMI causing distortion in your picture. HDMI cable will work trust me. I had same problem

I had the same problem. I hooked up the rca to see the screen with rca selected on the xbox cable and maybe under settings too in a menu. Then back to componet and turn the xbox on and off with componet. Worked ever since. I have an old xbox 360 with no hdmi so not sure if the new ones have the selector on the connection when it goes into the xbox, but basically after switchin back and forth the componet worked and no problems since.

I guess one thing to rule out is the input. If you have component cables instead of hdmi, you might have one of them loose. Also like they have said, to reset your pictures setting to default. Also try different sources if you can (Cable, dvd, blu ray) to see if it does it on all of them. The off brand one I bought has a slow warm up time and randomly starts to flicker the screen slightly. I learned my lesson and I will buy the more expensive factory replacement when this one goes out. Let us know if you still are having trouble after trying these things.

Thanks for the feedback, just to update the situation I bought a more expensive HDMI cable made by Belden, same problem no signal when using HDMI. I was going to switch the box as well but I guess this is useless. I guess all you can do is complain until verizon fios comes to my area

After checking all cables are correctly installed be sure you tell your TV where the signal is coming from. Example: On Samsung remote you have a 'source' button to select signal source//On LG you have an 'input' button to select source. If this doesn't solve the problem you may have a bad cable between TV/DVD. Swap cable with another and see if that cures the problem. Good Luck Susan.

I would try a different HDMI port on the TV. Some tv ports are not equal to others in the earlier TVs. The message sounds like a TV issue.

Have not had that issue. I have an issue with a 3D TV where the HDMI handshake on the TV end is problematic. It's mainly an annoyance as I can either delay turning on the cable box until the TV is fully up or just turn the cable box off and back on. Other than that it works fine. I would suggest trying another HDMI input device if you can for a test to eliminate any issues with your current device and try a different cable for the input. If you have more than one output device connected start with just a single output device until you have it working solidly. Also make sure that the power adapter if firmly plugged in. If the power LED also comes and goes then it might be power related. If you have another power adapter with the same plug size and polarity you might try that just to eliminate any power issues. The vendor was very responsive (as was Amazon's tech support) with troubleshooting my HDMI handshake issue so try them too.
