DVI-->HDMI cable causes tv speakers to hiss and pop
I'm trying to connect my HTPC to my 42LG50 with a DVI to HDMI cable. I have a minijack cable carrying the audio.
When I have the video cable connected, the tv's speakers hiss and pop. The volume control and mute button do not do anything. When I switch to the DVD player on a component input, the sound works normally.
I tried connecting my iPod to the audio in, just to make sure, but that sound did not come out of the speakers, just the hissing.
I connected my macbook to the tv using the same cables and it works fine.
I'm going to try upgrading the video driver to the very latest, but I'm not sure that'll do anything.
My HTPC is running SuSE Linux 11, and has an Nvidia graphics card.

Hi Jatinder Kumar ,
Yes you can connect your computer output to lcd tv through dvi-hdmi cable or vga-hdmi cable.
1. Connect to HDMI (DVI) : just plug in HDMI (DVI) out of PC or laptop to HDMI or DVI TV. Than select source from HDMI.
2. Connect to PC : Plug D sub to TV, select PC in.
What problem are you having? The connection should be fairly straight forward depending on your computer's video out. You can use a VGA cable, DVI to HDMI (check your graphics card manual for single link or dual link on the DVI side), or component video (even S-video). If you have HDMI out on the video card, use an HDMI cable. If you want to connect to the TV's speakers, you need at least an 3.5 mm audio cable (or 3.5 mm to RCA audio).
The DVI cable can be either a DVI to HDMI cable or DVI to DVI or HDMI to HDMI with a DVI to HDMI adapter at one or the other end.
I hope this helps.
Cindy Wells (you will need to go through the input modes to find the signal. Some TVs need to be on (with no signal) before the computer is turned on.)
Your cable must be a minijack to 2RCA. Minijack connected at line out on computer and 2RCA at AV1 in or other available port in on HHTS(Home theatre) (white and red socket). That is sound only. Video will be yellow (or vga/DVI/HDMI depending on graphic card)from your graphic card to AV1 in. same port as sound. Now select AV1 on HTS. If no picture on tv make sure you computer graphic card is set for dual display .

I just bought a Panasonic TH-42PZ800U and had the same problem. 10
blinks and the TV would not start. Then after some trial and error I
solved the problem!
Here is my (apparent) observation and solution:
I had only one input into the TV, which was my HTPC connected via a
DVI-to-HDMI cable plugged into the Panny's HDMI 1 slot. *IF* the HTPC
was already on, then the Panny would have the blink of death. *BUT* if
the HTPC was off, the Panny booted fine (assuming I cleared the blink
of death first by powering off the HTPC, unplugging the TV, and
replugging the TV back in with the HTPC still off).
My solution was to move the HDMI cable from slot 1 to slot 3. After
making this one change, everything worked as it should. No more 10
blinks of death. I could even leave the HTPC on and turn on the TV
last, and it still worked. Tried this 10 times, worked 10 times.
I don't know if this will solve other people's problems, but I hope it
at least provides some clues. I wonder if this is a fundamental circuit
design flaw on the part of Panasonic, rather than a "bad batch of

You have the same problem i have. My Tv just did the same thing 3 nights ago. I unplugged the set, and let it sit ofr about 6 hours, and then tried it again. It turned on and played, but repeated the problem after about 20 or 30 minutes. So far all my research has led me to believe that its a power supply issue. Problem is, there are 5 boards in the tv with seperate pwer supplies, and the 10 red flashes indicate that its all of them. :-(. Im shopping for a new TV, and It wont be a panasonic this time.
You should be able to use this with only the DVI connection as just a large monitor. You can use a DVI to HDMI adapter as I do believe the display is HDCP compliant. Many AV receivers will upscale to the necessary 1920x1080p resolution that the display needs.
