I get sound on new channel but no picture with invalid format across the screen. Why ??? What does this mean


the format used when you tuned is incorrect
the correct way is to go to the onscreen menu and find the tune section and go auto tune
allow time for the auto tune to find all channels then exit

On one channel...PBS we do not get any sound. Sound is ok on other channels and works on the other tv in the house


This television must have the ability to broadcast channels in SAP. Look for an SAP or MTS or AUDIO button on your Sylvania remote. The audio menu might be the place to find this setting as well. You want to remove the SAP and have the tv in either mono or stereo.

New LG 32LD350 - Allowed TV to auto-program channels, and for some reason, it skipped past channel 4 during the tuning process. When I select channel 4 in the tuning options, it comes up as no signal. On...


When you are auto tuning the system will not store a channel which is week by its standard ( at least 60% signal strength ) This done to avoid grainy picture and hissy sound.
You can go into manual tuning and store it.

Lg tv has no picture nor sound just the backlite, the remote control works, because when I press any key the power light flashes


The sound and video signal on LGs are driven directly from the mainboard which suggests a faulty mainboard..If the channels were tuned in previously to the fault then this solution is futher backed up. If the channels were not tuned in prior to the fault then you wont get any sound until the channels are tuned in, and it would not be possible to see the menu to do so. The prescence of REMCON pulses suggest the PSU is delivering power to the mainboard..Id go with a new mainboard but providing the channels are tuned in ok with no sound.

Any idea why on my new sharp 32" lcd tv, all cable channels except 57 & 58 (CNN) work fine, but on these channels the sound goes off and on, like there is a short in the sound. all other tvs and cable work...


If you do not have problems with picture and sound on all the other working channels, then the problem you are having with 57 & 58 cannot be a short. The problem you are having is that those channels will not tune in properly through your tuner and this is why you get intermittent sound when they are trying to tune in. The sound tunes in easier than the picture. You said that you have programmed the channels again and I am assuming you are talking about the autoprogramming mode. Try to program those channels individually by deleting them and then readding them. If you cannot do that then you need to take the tv back since it is new or have warranty service look at your tuner and setup your tuner by making adjustments to it directly. Good luck and God bless.

I have a poloriad flat lcd tv now channel 40 is the only channel where their is not sound all other channels have sound. We have cable and our other tv on channel 40 is ok but on the poloriad no sound on...


Could be the tuning of channel . Try doing an automatic channel search again and see if it will tune in more closely and get the full audio level.

Also, you might try a hard reset of the internal soft codes by unplugging it overnight to allow all the internal emproms to reset.

If the cable is passing through a vcr, could be the vcr at fault, too.
