    I have a Toshiba 42 flat panel hd tv. Has beautiful picture and sound on all but channel 15TBS. Signal is almost non-existant for only this channel. Had repair person out and they updated the software, but no fix. Suggested problem could be with cable. Going to try to change older cable that was in the home when we bought it with newer type cable and connections as we were told by the cable man when he installed it, if we bought a hdtv, it might hamper the signal.

    I have a Grundig Xentia with a similar problem..It has great picture quality and sound on all channels.  recently one channel does not have sound coming through.  for a few weeks it would sometimes work but recently no audio - the rest of the channels are fine.  All channels share the same cable as far as i can tell.  If anyone has a solution I'd love to hear!

I had the same problem... try toggling through the "SAP" (multilingual audio feeds) for the channel. Mine was somehow set on "audio 3 of 3" for that channel, but there were only 2 audio feeds.

Channel 3 is normal for that. Always have it on channel 3 on the TV set. Then you can work with it. Check your stuff and see is there a switch to set for channel 3 or 4, if none present, put it on 3, then start from the menu to set it up with remote.

We have a TCL 32"


It sounds as though the battery backup for the memory has failed, some sets use a cell battery like the ones in a pc or some watchs, some have a plastic cover with a cble which connects to the circuit board. Have a look around inside if you are competant, but be careful, make sure the set is switched off and if you dont know what something is then dont touch it. Even when switched off, some tv's can store enough voltage to kill you.

Only channel 9 no picture but got sound in LCD TCL BRAND


Make sure in the menu that you are using cable instead of antenna - then do a channel scan if you are using a coax and not thru a cable box. Have you tried any other inputs to ensure they are working properly? Please reply if you need additional assistance.

Thanks,

I have a TCL L42M61AZ LCD TV. I find that the "Channel 9" programs in Adelaide, Australia, namely GEM, GO and Channel 9 DTV will not show a visual picture, only play audio. All other programs are...


A firmware update from TCL will fix the problem. Call them and they will send out the firmware and a serial cable (required for update) for free.
I did the update yesterday and it fixed the problem (sound but no picture).
You will need a PC or laptop with a serial port (RS-232).
