Most televisions have a setting that controls whether the TV uses its internal speakers or sends the sound to the audio out jacks for an external amplifier or speakers. This setting will prevent any sound from coming out of the internal speakers.
Try going through the settings menu and follow through the audio/speaker selections and confirm that the TV is set to use internal speakers.
Best Regards,
It could be either internal speaker damage, internal circuit damabe or problems with the headphone jack. Try plugging in headphones if you have sound then you have no internal circuit damage. Try cleaning the headphone port with a cut off Q-tip. Also sit it in a warm dry place for a few days. If the sound still does not work the speakers may need to be replaced.
I'm not familiar with your exact product, but Parts Express sells all sorts of replacement in-speaker amplifiers. I've replaced several powered subwoofer amplifiers with their products, and the customers usually report-back that it sounds better than when new. You might want to check them out, and see if they have one that will fit.
Please confirm whether you are using external or internal speakers. If those are internal then it may be because of unavailability of the sound card drivers. Try to install those drivers and you will be able to hear the sound from inbuilt laptop speakers. Do let me know your laptop make and the operating system which you are using. I will send the direct link to you.
Hi, you might need to replace Some damaged resistor controlling the sound function. Please if no basic experience ,contact a repairman.
Replacing Damaged Resistors
Disconnect the stereo at the plug and remove the outer case.
Confirm that the resistor is damaged by testing the tolerance with a multimeter. Melt the current solder with an iron and remove the damaged resistor.
Mount the replacement resistor onto the circuit board. Trim any surplus lead material from around it.
"Tin" the tip of the soldering iron by melting a tiny amount of solder directly onto it. Remove any surplus solder and place the tip straight onto the circuit board.
Melt a tiny amount of solder straight onto the joint, using the solder spool. Ensure that the solder does not touch the tip of the iron.
Melt the solder straight onto the area between the resistor lead and the printed circuit board. Leave it to set and ensure that the joint is strong. Reassemble the stereo and test it.
Also Spray the volume control knob with electrical contact cleaner. Twist the knob from low to high to make certain that all the workings are adequately lubricated. This should eliminate any interference that you've experienced when adjusting the volume.
Check the condition of the speaker wires if the stereo is emitting no sound. Ensure that no bare wires are coming in contact with each other. This will result in a dead short. Replace any damaged wires with new ones.
Check the connections of all speaker wires if no damage is detected. Ensure that the wires are securely connected at the back of the stereo and at the speakers' connections. Confirm that the positive and negative connections on the stereo are connected to the corresponding speaker connections.
This is a possible damage on the internal speakers or a connection fault at the headphone jack connector. you might need to open the laptop to check and confirm on the connectors.
Hello
There are two possibilites for this fault. The first one is, damaged speaker voice coil and the second one is damaged audio output IC. To confirm it you have to open your TV. Speakers can be checked without removing them from the cabin fittings. Check them with the helap of a multimeter; set in OHms range. You can alos check it with a standard torch cell also. Connect the two terminals of the torch cell to the two terminals of the speaker [intermittantly, not constantly]; will produce a 'thumb' sound; if the speaker is good.
Connect the 'audio out socket' of the tv, with any other audio equipment, and listen whether there is sound form the external audio equipment, like amplifier or so. If there is sound from the external audio equipment, and no sound from the internal speaker of the TV, and the speaker is good, surely the 'audio output IC' of the TV is damged and should be replaced. OK.
Steps to be followed:
1. check whether audio driver is installed properly ? if not install audio driver & check 2. check audio setting in control panel & confirm 3. connect external speaker in laptop and check whether sound is coming? if sound is coming then ur laptop internal speaker need replacement 4. if there is no sound in external speaker then need to check ur motherboard or sound card. All the best.
Hello, you might have to replace the main board because you might have damaged the speaker plug. Make sure also before you make any decision you check the in the menu under the audio tab that the speakers are set to internal and not external. If you would like to find more information on the main board please send a quick email to [email protected] or to myself at [email protected] so I can provide you with part#, price, and availability of the board. You can also visit www.shopjimmy.com for prices on the main board for this model. Please rate my comment if it was helpfull to you.
