Question about Philips 37PF7320A 37 in. HD-Ready LCD Television

1 Answer

Audio switching rapidly between mono & stereo

I operate a small CATV plant. Some of the channels in my lineup are mono (news and such) while others are stereo (premiums, music channels, etc. One of my customers has the Phillips 37PFL5332D/37. He's experiencing severe audio distortion, but only on a few channels, and only on stereo channels. One the channels with the distortion, pressing the "info" button on the remote reveals that the audio mode is switching rapidly between mono & stereo. I ran him a new home run (signal strength is decent), and even brought in a nice Holland line extender to see if a hotter signal would solve the problem, but no luck. I'm beginning to think it's the TV itself. Has anyone else ever heard of this issue? Thanks.

How do I get my rca truflat tv to get out of mono?


Hello
Press the MTS on the remote control handset to select STEREO, MONO or SAP. All the options will be available only when the current TV channel is broadcasting that option. Channels will not always carry programes, that have all MTS options. If "STEREO" appears on the screen when you select a channel means stereo sound is available with current programme. You can hear sound from both speakers. If broadcast is not strong and clear, stereo sound will not be available. Press "MTS" button to change it to "Mono". This will eliminate the noise. If "MONO" appears on the screen when you select a channel, stereo effect will not be availabe, even though you have set it to stereo. If "SAP" appears when you select a channel 'Second Audio Programe' [SAP] broadcasting is available for that programme. Press the "MTS" button to 'SAP' and you can hear that programe in different language or some other kind of audio.

No output from one ch on old JVC VN-300 audio amp in stereo mode, power stage seems ok as both ch work ok in mono mode.circuit diagram, anyone?


The stereo/mono switch in most amps mearly feeds one channel to both channals when in mono. However it does mean that the Power Transistors (or whatever does the main output) is working on both channels. Therefore the dead stage is in the pre-amp part. Remember that the two channels will have the same parts as each other. The advantage is that one will have working parts and the other wont. So you can compare the two channels with voltage tests, using a multimeter.

No sound on some channels, other channels fine


Your SAP/MTS function is most likely turned on. This feature has 3 modes: Stereo, Mono and SAP. Stereo and Mono are easy to understand, it's the SAP that can get you. SAP stands for Second Audio Production. It is used to provide weather, information or an additional language translation of a program. Some broadcasters simply transmit the mono audio over the SAP audio channel when the are not using it for other purposes. Other broadcasters simply do not use it, which does not give you any audio. Look on your remote for a SAP or MTS button. If you do not see one, look in your TV user menu for this feature. If you are using a cable box, look in the audio menu of the cable box. You are looking for something set to SAP... just change it to STEREO. I hope this was helpful.

Audio with digital channels, no audio with analog channels


I was getting a constant mono setting for all channels with no option to set it to stereo. I called Sharp, and they said that in order to receive stereo sound, you cannot use a standard coaxial cable. You need an S-Video or HDMI cable. This not only resolves the mono audio issue but also resolves the analog (vs. stereo) issue. Hope this helps!!

Can't view all my channels on LXI series TV


For anyone with a set with this problem that is older----IT DOES NOT HAVE THAT PART OF THE CABLE BAND BUILT INTO IT--only solution is either to put a cable box to it or buy a new set.

Installing PA5422 in two channewl mode


Since your first paragraph is leading to your question paragraph, I'll adress that. "what is the difference amongst the MONO/STEREO/L+R switch options available on both Front and Rear AMP X-over Sections of the PA5422?" Mono is same sound output on each channel, stereo is what you want as it gives out stereo sound, and L+R is most likely blending the channels together.
