Re: Sound goes out in speakers
Welcome to Fixya!
You should be able to remove the jack, and the speakers will be fine. OR if it is a board mounted jack, you can use an x-acto knife to cut the circuit traces going to it. - either way this will work.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

lets verify first to narrow down where the problem came from. check first the on screen sound set up menu if set to off. if ok, tried to hooked up a powered pc speaker at the audio output jack of the tv. turn on the tv as will as the powered pc speaker, if you can get sound there the cause is bad amplifier circuit with in the main board. but if you can not get sound there the cause will be bad sound processor at the board.
Ok if I understand what you are saying. You are going from your TVs audio jack into an amplifier TEAC AG-V8050 and then into the Sennheiser T1250 unit? This is done to amplify the sound so your wife can hear the TV via Infared into headphones I am guessing. The connections would have to be as follows.
TV RCA jack (Installed by someone to TV audio Output section, most likely the speaker) to the Amplifier TEAC AG-V8050 via RCA cable then from the Amplifier via RCA cable to the Sennheiser TI 250 IR Transmitter. The transmitter then takes the audio input and turns it into a digital signal which is transmitted via IR to headphones which your wife is using.
First of all the amp TEAC AG-V8050 is not needed. what happend here is the person doing the installation took sound off of a preamp to avoid having to deal with the TV volume control. This works but it makes matters harder.
So here is how you troubleshoot this problem:
1) Disconnect the amplifier and plug the RCA jack of the TV into the RCA jack of a set of amplified Mono headphones. (This is to determine if sound is coming from the TV)
If not the problem is in the TV audio section and you will need to take it to a TV repair shop.
2) If audio is coming through the headset the trouble is in the amp or the sennhiser unit. To test the sennhiser unit: plug the sennhiser into the audio out of a VCR and listen in the headphones for sound. If you have sound, the sennheiser is good and the problem may be in the amplifier, but if you do not have sound the the sennheiser is bad.
3)Connect the audio out of the VCR into the audio in of the amplifier and plug the output of the amplifier into the sennheiser which tested good with just the VCR alone.
If no sound is present then the amp is your culprit.
Once you find out which component is the problem, I would suggest finding a rapair shop here on FitYa to repair your unit or having an electronics technician come to you to fix the bad component.
This should help,
The switch of the main speaker does not engage when you plug inn your earphone it's suppose to turn off the main speaker.you need to clean the contact of the switch of the jack.Open the cover of reciever and go to the earphone jack spray it with a contact cleaner then try again.if the same thing happen replace the jack with a new one.
We solved the problem by purchasing a surround sound system and hooked it up to the Cable box thus bypassing the TV speakers. It was a cheaper fix than having a TV repair service guy come out and we have even better sound! Thanks anyway!
Maybe the sound is muted. Try pressing the volume up button to restore sound.
• If using S-Video or Y, PB, PR, remember to also connect the component’s left and right audio output jacks to the TV’s L and R Audio
• If you're using the TV's internal speakers, make sure the INT/EXT switch on the back of the TV is put on “INT”.
• The sound settings may not be set correctly.
This is an indication that the actual sound output is working, but the amplifiers to the speakers are not. How you could take care of this is to check in there are any loose connections to the speakers. Then check if you have sound coming from the leads of the output stereo amplifier (You will need the schematic and an audio tracer/tracker to find this location and test for sound). I would venture that there would be no sound from the amplifier. If not you will have to replace the amplifier chip. I would suggest getting a qualified TV technician to perform this task. If you do have sound at the output of the strereo amplifier chip, then it might be a case of the earphone jack switch being broken, let me explain when you plug in your earphone the speakers are disconnected by a switch in the earphone jack if this switch is broken it could disable the speakers and produce these results. There is also the possibility that you have the speaks disabled from the menu of your TV (check this too, actually check this first).
