No digital sound. Digital picture, analog picture and sound are fine. cable checked out ok. Every now and then weak and distorted sound will come on for a few seconds and then go off again.

If you actually have the Zenith model TV (B25A24Z), the trouble is not in your set. This model has only an analog tuner, and what it sounds like you are describing is digital pixellation. This is what happens with a digital-to-analog converter box when it gets a weak signal, with rain fade or heavy snow on a satellite dish antenna, or when a digital cable system has some signal problems. The converter equipment locks the last complete frame (or breaks up into blocks and freezes) and the sound is muted.

You'll need to look for the cause of your trouble in whatever is feeding the TV. If you have a digital converter box for off-the-air broadcasts, make sure you have a good antenna and all the connections are tight. If you have satellite TV service or digital cable service, you might need to contact your service provider for help in troubleshooting and fixing the trouble.

Check the Image source if well shielded. Weak or broken shield in cable will affect the video-sound quality. Try different cable and analog video source. Once you ensure that nothing is wrong at input side. Uninstall-Reinstall the driver and the accompanied software also update driver and the software from Pinnacles support website.

Good Luck

possible weak digital cable or digital satellite signal from cable line or satellite antenna.

If you have an analog tv you will have a weak or no picture and sound. You will need to have cable (e.g Virgin) or Sky before 2012 because after this time all television broadcasts will be digital

if u have placed your DVD next to your tv ... just maintain distance between then and check out

When the Government decided to make all stations go digital, most places we're telling about the change over. But what they forgot to mention to the ones like you that you may have to change your outside antenna. They make antenna just for picking up digital signal. So you may have to change that also. be Sure and check the cable going from the ant. to back of the converter box is in good condition or may have a break somewhere that could cause more trouble. If you see any bad places on the cable you may want to replace it now when you do the antenna.

Sounds like you've lost your red video signal (chroma) somewhere along the line. This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. The analog has all your inputs on it, except DVI and RGB which go straight into the digital board. The digital scales (upconverts) the signal to HD (1080 or native) and sends it to the DMD or light engine. See which inputs are distorted. If only DVI is clean then you problem is the analog board. If you menu and everything is distorted then suspect the DMD board. If you run component or DVI through the resolutions (480i, 480p, 720p, 1080i) you can get an idea between the digital board and dmd. The menu is generated on the digital board. Somewhere red is getting lost.

Check your battery, if your battery was low it may cause picture distortion. ^_^

A few questions... What components are involved? How are they connected? Can you hear sound from the speakers for any other input device i.e. radio, cd, vhs, etc.? I suspect that there is an issue with the way the system is connected. I have the Surround sound output from my DVD player connected to the digital surround sound input on my reciever. I'm using digital coax cable (looks like a "normal" RCA cable), not the optical fiber connection. I had to buy a special cable for the digital surround sound. A normal RCA cable would not work. I don't know why. If you're using a similar connection, that could be your issue. make sure that the output and inputs you're using are compatible. A digital surround sound connection (in or out) can't be connected to an analog connector (in or out). Remember, Digital to Digital with a Digital capable cable; Analog to Analog with an Analog capable cable. If this is not your issue, post back here with more info and we'll see what we can figure out.

Are you getting this on all video outputs from the DVD? the yellow analog out + the red/blue/green + the S video? Did you try connecting a different source? a digital cable TV tuner, or another DVD player? sometimes DVD players get screwed on some outputs, while the rest stay fine. I have a DVD that has an analog video out that shows an only black and white picture, while the red/blue/green works fine. Good luck
