    On my Visio XL 32 most of my channels pixelate and the sound skips. I hooked the TV up about 5 days ago with no problems. The problem started out of the blue.

    I have an Hitachi 55HDS69 TV and one of the HD channels has no sound? The picture is fine but it just has no sound. If I go to the regular channel and not the HD channel it works fine? All the other HD channels seem to work ok also? Cannot figure out why only one HD channel does not have sound? Anybody have this problem?

Is this a HD channel? This is usually caused by a hiccup in the streaming of HD from the cable/sat company. How long has this been happening?

I am getting no sound out of my Panasonic Viera TH-50PX80U Plasma TV


Are the speakers' cables connected correctly? (p. 37) Is "Sound Mute" active? (p. 13) Is the volume set to the minimum? Is "Speaker output" set to "Off"? (p. 22) Change "SAP" settings. (p. 16) Check "HDMI 1 in", "HDMI 2 in" or "HDMI 3 in" settings. (p. 22)
Hope this helps, page# refer to your manual.

Connect with componet cables.


The only digital audio input for this TV will be via the HDMI input. Of course, even with HDMI in, you're only going to get a simple stereo output from the TV. You can use the analog L & R audio inputs for a very similar sound from the TV speakers.

The digital multi-channel audio (Dolby Digital, THX, 5.1, 7.1, etc) encoded in the program should be connected to a suitable multi-channel amplifier with either a TOSLINK (optical), RF (coaxial) or HDMI cable for theatre-like sound. This can be done by (a) cabling from the source (DVD, BluRay Disk, Set Top TV Tuner, etc.) directly to a multi-channel amp and speakers, or (b) from the HDMI output of these devices (DVD, BluRay Disk, Set Top TV Tuner, etc.) into one or both of the TV's HDMI inputs. This will provide only stereo sound output from the TV speakers. You should connect the TV's TOSLINK optical "Digital Output" jack with an optical cable to the amplifier's TOSLINK optical input jack to obtain theatre sound.

To listen to the program shown, you would select the amplifier input assciated with the optical, RF or HDMI input that is connected to the source (DVD, BluRay Disk, Set Top TV Tuner, etc.) if connected directly. If the TV HDMI input(s) are used, they are output to the TV optical output and should be connected to the amplifier optical input. The amp input associated with the optical input should be selected to hear the program with theatre-like sound.

Here's my setup: 46"Panasonic Viera


I'd call the cable company, it sounds like you have an issue with the cable box.

Can i connect my panasonic viera th-42px8ou plasma tv,to my vista desk top? my tv has hdmi on it,my vista tower also says it has 1 hdmi connector on the back of it


You can buy an HDMI to DVI adapter (around 20$) to connect your HDMI computer cable to your TV. You will need separates audios cables, right and left, to bring the sound to the TV.

Got a svga/hdmi cord and hooked up for my panasonic viera plasma to my computer but nothing shows on my component 2. also wondering if i'll need a cord for audio - i have double red/white/yellow...


You probably would need the extra audio cords seeings as normal svga connection won't suppost sound streaming. mixing and matching connections is always a pain to perfect.
If you are using the HDMI end on your plasma, then you will have the video show up on the HDMI channel. Then get an RCA red and white pair - 3.5mm jack and plug the jack into your PC's audio connection port and the RCA's into the Audio In ports in the back of the TV.
Once done the TV should display video and play sound from the PC. Failing this, try a few different configuration but always keep the audio plugged into the same Audio in port on the TV. Bacause then you at least know the channel that the audio works on ;D
Hope this helps mate, any more q's just ask!

Just bought a 50 panasonic viera, when we hook up ps3 on hdmi cable, we have sound but no picture.


Plasma TV normally do not have the resolution required for PS3 unless the plasma TV is fullHD( 1920x1080p) pixels.

HD Ready Plasma = 1024 x 768p
PS3 Outputs = (fullHD)1920x1080 or (HDReady) 1280 x 720p.

LCD TV accepts the resolution matches the resolution the PS3 is outputting.
