No sound is coming from the speaker itself although sound can be heard with a earphone inserted into the jack on te speaker

if their is a sound from the internal speaker then the problem is with in only in the earphone jack or in the connection. to access the internal part of the tv you need to remove the rear cover. locate the earphone jack terminal re soldered and check the connection at the board ( PCB). you can check also the continuity, attached powered pc speaker then use an analog tester and check weather their is a connection coming from the stereo input jack going to the terminal of the earphone jack of the tv. if no connection replace with new earphone jack. good luck hope this can helped.

Most of these combo units do not have a speaker ON or OFF setting but look anyway.

If the set has a earphone jack that may be the problem--see if works with earphone plugged in.

The socket the jack goes into can get flaky as when jack is inserted it turns the sound OFF.

Also put your ear right to the speaker to see if anything at all is heard--the speaker could be bad--but check the above first.

If you are saying when earphone plug is inserted you still have sound from speakers either jack on headphones is wrong(stereo or mono?) or the socket the jack plugs into is defective---when a jack is inserted it moves a leaf in the socket to turn the main speakers off.

Hi Ted,

This kind of symptoms indicated of fault either the internal speakers or the earphone jack itself. To isolate where the fault came from, the speaker's resistance inside the set needs to check using the multimeter/ohmmeter.
Watch the video below to give you an idea how to test the speakers.




If the speakers are in good condition, then the fault came from the earphone jack itself. It has a built-in switch that will open/closed once you plug in your headset to cut the sound coming to the internal speakers of the TV and hear the sound only to your headset. The problem is, if the contact stuck or dirty, the sound will not pass through the speakers. You have to spray it with electrical contact cleaner while inserting and pulling the headset plug to clean the contact.

Hope I helped you.

Hi hotrodjayrod,

If the symptoms remain the same after trying another headset, this kind of fault is caused by bad solder joints in the earphone jack itself of your unit. This is due to frequent inserting and pulling the headset plug. To resolve the issue, the earphone jack must be re-soldered. You have to open the back cover of your player and using a pointed soldering iron, re-solder the joints.

Hope I helped you.

Hi,

If you can hear the sound from the headphone(earphone jack), the fault is between the headphone itself or the speakers. Check the continuity of the speakers(voice coil) using the multimeter to determine if it is faulty or not.

If you've confirmed that the speakers are not the issue here, you may spray an electrical contact cleaner to the earphone jack of your unit while pulling and inserting the headset plug to clean the contact from dirt build-up inside. You may also replace the earphone jack with new one to back the unit in normal operation.

Hope I helped you.

Hi kohn,

Plug your headset to the earphone jack (if installed) of the TV.

If you can hear the sound there, the fault may due to open(defective) internal speakers or the earphone jack itself. Faulty internal speaker may replaced with new sets to back your sound to normal again. If the earphone jack was faulty, you may spray it first with electrical contact cleanerwhile inserting and pulling the headset plug into it for one minute to clean the contact. If nothing happens, this jack need to replaced with new one.

If you can't hear the sound after inserting your headset, this is an indication that the audio circuitry was gone bad. The most common caused of this trouble was the faulty sound IC(mounted in heatsink). This is the one converts the audio signal to sound and feed to your speaker's. I would advice you to look for a qualified technician to check this parts.

Hope I helped you.

Have a nice day!

Hi qlane1,

First make sure that the sound is not in "mute" mode.

Plug your headset to the earphone jack (if installed) of the TV.
