1 Answer

TV sounds is very low

Hey experts -- my TV is having some audio issues. From normal cable via coax,TV volume has to be increased to full to hear even the slightest bit of audio. When using the DVD player through a standard Red/White/Yello RCA cord, volume works fine. Any suggestions?

The following pertains to most sets of this type. I am speaking generaly and not model specific.

The fact that you can have sound from a direct baseband source, tells me that the fault is in the sound demodulation areas.

If you can have a cable TV box with A/V output to the TV, then the set would not be dependent on the tuner and sound demodulator. You would also have a nicer cable picture and better sound than what its tuner can do.

--

Before worrying or going drastic, check that the set is not in the SAP mode. It must be in the MAIN or Stereo mode. You will need the original factory remote to verify this.

In the IF module there is a sound demodulator circuit. If I remember correctly, this set may have another daughter board or another circuit area for the stereo processing.

I have had a number of sets come in for audio failure. In most cases we replaced the IF module to fix the fault. In some cases it is possible to service the module, but this is difficult without having the proper setup to troubleshoot and service it.

After the IF module is replaced, the AGC setup has to be performed. There is reference in the service manual for the setup of the AGC.

You may find it more feasible to have a Sony service tech service the set. This way you don't have to start buying modules and parts to try.

It may be cheaper and better for you to get a cable box for your cable service, and feed the set A/V baseband from the box.

With the advent of the new LCD and Plasma technology, you may want to put the repair cost in to a new and better set!!!

No audio,tried menu items and selections,nothing.The sound just went out,what do you think it might be?


There is no sound or low volume coming from the television speakers.
Solution Follow this procedure to troubleshoot when there is no sound or low volume coming from the television.

NOTE: Because each of these steps represents a possible solution to this issue, check the television status after completing each step.
Increase the volume of the television. Ensure the television audio has not been muted. Ensure no headphones are not connected to the television. If using a set-top box with a volume control, increase the volume of the set-top box.
NOTE: If the set-top box is connected using an Audio/Video (A/V) connection, ensure that the A/V cables are connected securely to the appropriate video input on the television.
Verify that the MTS settings of the television are set to MAIN or STEREO .
NOTE: If the source device is not set to stereo or is not capable of transmitting a stereo signal, sound may come from one speaker on the TV only, and the volume will sound low. In this case, adjust or replace the source device.
If the TV has a Simulated effect in the audio menu, turn it off . Ensure the televisions speakers are not set as the center speaker.
NOTE: Some televisions allow the televisions speakers to act as the center channel speaker when using a multi-channel receiver.
Verify that the speakers are set to ON in the television menu.
IMPORTANT: If the television has audio output jacks and they are connected to a stereo system, then the speakers on the television may be turned off. Some televisions require the internal speakers or the center speaker setting to be off before audio can be sent out to a stereo receiver via the audio out jacks.
Ensure all audio and video cable connections are properly connected to the television.
Test the television using another source like a VCR, DVD player or Blu-ray Disc™ (BD) player.
Reset the television to the original factory settings. To reset your TV to factory settings, turn the TV ON. Then, while pressing the UP ARROW button on the Remote Control, press the POWER button on the TV. The TV will turn itself OFF then back ON.
NOTE: If your remote control does not have a RESET button or the procedure did not reset the TV to the factory default settings, perform a power reset.
If the issue is still unresolved after completing all the troubleshooting steps suggested, service may be required.

Toshiba CN36X81 television.. NO Sound... Great Picture. Using the TV2 output of a DISH Network HD receiver... TV2 output is std def, coax output. Using a different TV I get picture and sound... but not...


IF coming in via, the "Dish" networked receiver, please check that this volume is turned way up, on the TV. and then control the the Volume, with the Dish Remote, often this is a problem, as one is turned down, and the other cannot turn that up, simply try syncing the Volume controls, UP on TV, control the Audio with dish remote. thats all i can think of. Check by feeding a signal IN from an AV, source, ie: Yellow, Video, & Red& White, Audio. Turn TV UP and check, IF it responds to this all is well. If NOT then you do indeed have a fault, with the TV.

My tv got no sound..but if connect a video/dvd via rca ok.


Sounds like you have a tuner or an antenna problem. If you are using a DVT converter box to watch off the air TV, the signal has to be very good to get sound and picture. Try connecting a VCR or a DVD player trough the coax cable and see if it you get sound an pic on Channel 3 or 4. If you do, it is an antenna problem.

No volume


Things to check,

1. are you using an external cable/satellite box.
if the answer is yes , verify if you have the audio out of the reciver connected to a surround sound system
If you do have it connected to a surround sound system , verify the surround sound systems volume is up and on the correct source input on the surround sound system

2. if you do not have a external cable/satellite box and and or your not using a surround sound system, and the cable line is connected directly to the television via a coax cable.. then verify that in the audio settings configuration of the telivision you have not accidentally disabled the internal speakers, some tvs have this option , please consult your manual.

I cant hear the tv


Hello drive2darim,

OK first check you converter box, Cable TV/ Satellite TV volume control and turn it up to 100%.

Then check the menu on your TV for audio settings and set them to there default settings. This should take care of this issue.

I hope this helps,

Thank you,

I hear sound but no picture or video dont know why


It all depends on what you have connected to your TV and how you are connected. If you're watching a DVD via the composite (yellow, red, and white) it is possible your video (yellow) is connected to a different input on your TV than your audio. If you're connected via coax to a source such as an antenna, the most likely answer is your TV has a major issue.

Philips 27PS55S/121 sound level decreases


Yes, the dynamic range on DVD's is enough to cause the high and low passages to be somewhat annoying but, sounds more like a movie theater. This kind of dynamic range showed up first on Beta HiFi and VHS HiFi VCR's because of thier range as well. If there is a feature in your audio menus on your TV such as "audio expansion, SRS, Wide mode, etc." turn it off and let the audio be processed without expansion of any kind as that will amplify your dynamic range alot more. The lock up issue could be something Philips is aware about and if under warranty contact them. Otherwise not much you can do except manke sure the voltage going to the TV is failry stable between 110 volts and 120 volts. Sometimes dramatic drops and or increases can cause lock up or confusion to the microprocessor in the TV.
