My loptop has no sound from the headset jack.but my internal speakers has

The jack where the headphone plugs in is probably damaged. When the headphone is plugged in the internal speaker is disconnected. The switch is part of the jack and does not reconnect the internal speaker when the headset is unplugged.

When connecting a headset or any other audio device to a laptops 3.5mm audio jack, it is designed to stop the internal speakers and run only from Headphones.

If you mean that even after disconnecting the Headphones the internal speakers are still not working, ensure that the headphone jack does not have anything lodged in it, any metal object can trick the laptop into thinking there are headphones connected, cutting the internal speakers out.

Try getting a DRY cotton bud, and clean out the port with that, this will get rid of anything that may be triggering the problem.

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.
Have a nice day!

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 Steve,
This is an indication of faulty earphone jack, this is where the headset directly hooked up. See sample picture below.




When the you hooked up the headset to this jack, internal switch will released the contact to cut the audio goes to the main speaker out of the unit. Once you pulled out the headset plug, the audio will back to the main output speaker out through this switch.
In your cased, there's a malfunction in the internal switch of the earphone jack that's you haven't sound output at the main speaker out.
You may spray contact cleaner directly to the earphone jack while inserting and pulling out the headset plug to clean the lead. If the symptom still persist, you must replaced it with new one to back the unit in normal operation again.
Hope I helped you.
Have a nice day!

Hi qlane1,

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

1 - hi
2 - check the jack for headset
- if you heard any sound with headset = your speakers are burned
3 - if you always use this jack for head set its maybe got problem = when push or pull the headset jack if you hear any sound from speakers your headset socket should change
4 - if you didnt hear any sound from both (speaker and headset) it means your ampilifire should repair

Yes, the slot where the jack goes is faulty.
Common problem in all DV series.

assuming headset is right connector, right? and they work elsewhere? that's the only reason headsets don't work, is that the jack is incompatible with the socket for speakers..
