Intermittant lost of HDMI signal to TV

by jerseydevil495 / February 9, 2009 5:51 AM PST

I have a Samsung LN46A550 TV and a Samsung DVD/VCR combo, DVD-VR375. My cable box (Fios) is connected to HDMI 1 on the TV, an LG home theater is connected to HDMI 2 on the TV and the Samsung DVD/VCR is connected to HDMI 3 (video out on the DVD/VCR) on the TV. Anynet is turned on and the TV sees all my attached devices.

Here is the problem. When using my Samsung DVD/VCR it seems that every few minutes (not all the time but often) the TV loses the HDMI signal from the DVD/VCR and displays the message "searching for signal" and then the signal comes back again a few seconds later. I've tried switching HDMI cables, switching HDMI ports on the TV but nothing works.

I read somewhere that using component cables stops this problem but won't I lose the upgrade features on the DVD recorder if I use component cables?

Also, why does the TV, when checking "sources" show my attached DVD/home theater devices as both HDMI 2 and 3 respectively and also as Anynet devices? Is there any difference?

HDMI intermitttent loss of signal

I'm not sure why it is giving you a "searching for signal" message with the DVD player. It could be a setting in the DVD player to a bad cabe, either the cable itself or the connection in the DVD player or the television. It definitely sounds like a handshake issue, and any of those possibilities exist in that scenario.

Does turning off Anynet+ solve the issue?

Component cables don't have the handshake issues that HDMI ports do have, but they also don't send the direct digital-digital signal, as component cables have a digital-to-analog-to-digital transfer that happens. So it would still send a HD signal via component, but there will be a technical loss of picture quality. Some people can see that difference, others can't.

I have the same problem. I tried disabling Anynet+ but the problem persists. I tried different cables and different Blu Ray players (Regular player and ps3). So it's pretty much certain that the problem comes from the TV.

Like i said, disabling Anynet+ didn't solve the problem. I called Samsung and there is no firmware upgrade for my model (LNT4665F)

Any ideas ?

No signal

I also have this problem no signal on my direct tv box that's been working for 3 months then all of a sudden stopped working. I moved to different ports and nothing. I swithced cables and it worked temporarily and then stopped immediately. I'm really hot about this because to pay 2800 dollars for the 8000series 55inch LED and then it has problems 3 months into it??? Talk about dissappointed already! I can't see buying another Samsung if this doesn't get fixed. And the entire houston area will know if it's up to me. I called customer service and they were very rude and make it seem like it's never possible for a Samsung to mess up yet I search the internet only to see that Millions of customers have the same issues???? They need to make this right because this is just a horrible situation. People work hard for their money to only buy something that doesnt' work as intended that is very frustrating.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
