HTPC TV Issue - TV has No Signal

post #1 of 17
Thread Starter 
Our HTPC, http://www.overclock.net/system.php?i=65804, has been working, for the most part, wonderfully. We use Boxee and WMC for our media needs and SyncBack for our server backup needs. However, we've been having a rather annoying problem.

Sometimes when turn the TV on, the HDMI input shows No Signal. The HTPC is on; I can remote in just fine. Turning on and off the TV doesn't help. Restarting the HTPC works fine but when this happens multiple times a day, that isn't really an acceptable solution.

Any ideas?

Does this happen at any particular time? IE, after hibernation or sleep mode?

ok sorry just saw your link, it sounds like driver related to me but to be sure, what drivers are your running? and how long have you been having this issue?

It happens intermittently so I can't say for sure when it began. I'll update the drivers and see if that helps though I thought we were on the latest ones. Can't be too sure.

you can try the updated drivers and if that doesnt work i would look for downgraded drivers, like the 9 or 10 series drivers, but that might be tough as they use the same as the mobility drivers.

Sound like a HDCP issue. HDMI straight to the TV or is their a receiver?

HDMI goes straight to the TV. Audio goes optical out to receiver.

What kind of ports does it have? I.E. Does it have VGA and DVI along with the HDMI or is it only HDMI? If there are DVI I'd try
1. Checking to see if the cable is good by trying another. (if you don't have one buy one don't completely unwrap it and use it then return it if it's still not helping. It may not work depending on how far away the PC is from the monitor.
2. If the cable is ok try an adapter the circuits leading to your port may have an intermittent short, bad solder or something.
3. Have you tried another graphics card or are you just using the integrated?

Can you post some pics of your setup monitor, cable and distance from case,etc? They would be a nice reference.
