The sound on my Proscan TV stopped working. The picture is perfect, but when the volume is turned up a popping sound is produced. I switched the TV to external speakers and hooked up stereo speakers and the same sound resulted. Is this an easy or inexpensive fix or should I look for a new TV. The TV is 8 years old.
Thank you for your help!

Re: The video works perfectly but there is no audio
The best part is that you like the picture and that makes it worth repairing,before you call for an estimate tap on the side of the set and/or the jack panel to see if the sound comes back if it does react you are looking for a loose conection and the repair should not be expensive but if it does not react you might be looking at the stereo amp board and that can be expensive depending in your location,If you are familiar with tv service you can go as far as removing the back cover and taping on the chassis or in the area were the internal speaker wires conect to the chassis or the amp board but if you are not too familiar be safe and call for assistance from a servicer.

It sounds that the audio output section circuit to your TV has the fault. The audio output IC, or speakers should be suspected. Contact any service technician. If you're sound in electronics, and wish to get more details,
check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic
/ Time slide, can be selected by the drop-down list, at the top left

number/IC used, in the search box at the top right of the display window.
This is not how you explain your problems to others. It should be precise. In this case, you could have said that you connected the cable between the RF out put of set-top box and RF input TV. Or Audio/video output of set-top box to Audio/video input of the TV. Also you did not mention, to which port you had connected the Vedeo recorder and DVD which are working good. Now, it may the volume level of the set-top box at low level which you can try to increase by using the remote control
If you could not sort out the problem explain how you had 'dismantled everything'
Check all your channels. If you are getting sound on some channels but not others it is a good possibility that your SAP setting is turned on. Simply go into your audio menu and disable the SAP. Not sure about your model tv but some Tv sets had a switch on the back to disable the speakers and some have a setting in the menu to disable the speakers. If you have a digital cable box hooked to the tv it is possible the cable box volume is turned all the way down which will override your tv volume. Check these options and hopefully one of them works for you.
My panasonic did the same thing. turns out my coaxial cable hooking up the cable from the wall was bad. Once i unhooked it from the wall, the sound popped. I wiggled it a little on the receiver end on the wall and got sound. So try replacing your cable box cord and see if it fixes it.
Hello! Try the audio out. Run the audio to a receiver to see if the audio is there. If it is, then I'd leave it hooked up to the receiver and save yourself some money. If there is not any low level audio out then I'd fix the set. The only Sony set I've ever seen that was not worth fixing was a 32" model from the early 1990's that had bad picture tubes after only 5 years. I am a Sony factory trained tech. Good Luck!
this is a very common problem just unplug tv for 5 minutes it
should fix it . simple fix most of the time with rca and proscan.
If that does not do it go into menu scroll down to audio and then press on .
If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on. If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
These are the answers straight from the dell manual.
Ensure that the audio cables are firmly connected to both the audio input connectors on your LCD TV and audio output connectors on your PC or Video player.
If on certain TV channels you receive a picture but no sound, this means that you do not have the correct TV system. Modify the SYSTEM setting.
Check if TV volume is turn off of muted
Connect the audio cable securely
Audio cable is connected incorrectly
Verify that the audio source is selected correctly in the OSD
