Question about Zenith B25A24Z 25" TV

3 Answers

No sound on TV

I have no sound coming out of the TV at all. I have checked for switches on the back that might turn on or off the speakers, and have also checked it in the setup on the tv itself. Every other aspect of the tv is working just fine but the sound. Any pointers or something to try that I'm missing?

    I am not using the inputs at this time. I only have the coax cable connected and am trying to pick up regular tv stations. they come in fine, but sound is not there. My dvd player is part of a built in home ent. system, so it has it's own sound system.

    I'll check the inputs with a set of external speakers and let you know the result of that.

    Thanks for helping me out :)

    I think this may be an actual problem with the speakers.

    I went home last night and connected a set of speakers to the external audio jacks and got nothing at all. No sound. The only thing I have connected to the TV at all is an antenna (lol) and the 3 AV connectors for the home theater inputs. The home theater sounds fine because it has its own speakers, but nothing at all on the tv. I wouldn't have an issue with it if I could find a way to get the tv audio through the home theater system, but I haven't been successful in that yet.

    If you have any other ideas, please let me know. Otherwise, I think this will probably be a definite speaker issue, and I'll check with a repair shop on the cost to replace.

  • jim_073 Aug 16, 2007

    I already checked for that option, and its turned on. I appreciate you taking time to try to help me once again. I think the next stop will be a tv repair shop.

    Thanks again :)

Depends on what the tv is plugged into. Are you having problems with all inputs or just one (aka satellite and not dvd). what inputs are you using to connect this device to the tv, and what are you using to connect them?

    no problem. If you're using the coax in connection, i assume you're using an antenna to pic up tv.

    good stuff.

    if you have anything else at all connected to the tv, check and see if it will give you audio..DVD, vcr, satellite box, anything. if it does not , there may be something physically wrong with your tv speakers.

    if it's new, try returning it to where you purchased it, if it's old... you may be out of luck.

    An alternate is if it has a set of "audio output" connectinos on the back", if it does, y ou can get a small stereo to hook up instead of using your tv speakers.

    A guy could always use a VCR as a tuner instead of your tv, and connect the vcr to your stereo. worth a shot if you're in a bind, otherwise, all I can offer is check in the menu system for an "external speaker on/off" setting I have an older panasonic that had this option

No sound coming out of speakers tuner or cat/tv

Please add details of setup so I can help you. For example. My Directv box hooks into my HDTV HDMI. Sound is carried inside that cable. I then get sound on my TV from my Directv RCVR without any other hookup. But I do have more. I use an optical cable to go into my Denon 1312 TV/optical input. Since my Wii, PS3, VCR, and formerly Xbox360 all plug into the HDTV inputs and I use it to switch. The Denon is not HDMI capable so this is best for me.

This is the first thing I would try. hook the HDMI to your HDTV from the CATV/SAT box and turn up the sound on the TV. [Box and TV on and correct input used] If you hear audio, the hook it back up as before. Now, turn on the Denon to radio. and turn it up. Got sound?
NO: check speakers and speaker setting. Let's say you have speakers hooked to A but not B. is the selector on B or AB. That won't work. It has to match the hookup. If speakers are on A only, select A only, etc. Also check with known good speakers. Also check all cables to be plugged into the correct spot and plugged in fully.
Thanks PM me if you need more help.

check the simple things:

Does set have sound when a DVD etc. is connected via the audio/video jacks?

If using a box check to see volume not turned way down there (unplug box and after a short wait plug it back to let it reboot).

check in main menu that Speakers are not switched OFF.

If set has hook ups for external speakers--is set turned to Internal or External?

if no to all the above you have a audio circuit problem

No sound


First you check the speaker of your Daewoo Tv. To check the whether the speaker is good or damaged, place your year very close to the speaker side of your TV, and switch the TV by its front panel power switch, not by the remote control. If you can hear a "Thumb" sound from the speaker, as the TV is switched on, the speaker is good and you have to to further. If not speaker has got damaged and have to be replaced.
If your TV is provided with an earphone or headphone socket at its fron panel, insert a earphone or headphone pin into it and listen whether there is sound coming from it or not. If ther comes the sound, it doesnot comes to the speaker, means that the headphone or earphone socket is faulty. Replacing it will solve the problem.
If there is AV OUT from your TV, connect it to an amplifier or so to get the sound. If there is sound and no output from speaker, means the Audio Output IC inside your TV is faulty.
Just locate the audio output Ic, and replace it with same type and number. Audio Output IC can be easly located ans speaker wire goes to that section, and follow the speaker wire. locate it. If you need any more assistance, feel free to contact me through Fixya. OK.

No sound coming out of my Mitsubishi Model CS-2013R (older model). Picture is still great. Just no sound all of a sudden. TV nor DVD player (running through it) project sound...

The older TV's have a switch in the back what if bumped will cut the speakers off. It is for internal/external speakers. Check the switch & make sure it is set for internal speakers. If that still does not solve it, go to your Menu screen advanced options and make sure the speakers are turned on. If it is and still not audio, then you may have a problem with the internal amp or the audio switcher. Note you will need the factory remote for the advanced options

I have a panosonic plasma tv when i switch it on it tell me there is a speaker short and then switches it self of model number pdp507xda help

It's the internal circuitry problem. Try muting it and put audio connection to other speakers if it repeats, your TV audio system is internally dying.the audio connections has to be checked and faulty components should be replaced.
1. Speaker short.
Open it up and check the speaker connections. ONLY if you have basic skills working on electronics and don't have a warranty.
2. Sound Volume "Leveler"
Look in your sound option menu for a sound "balancer" option and turn it off.
If this doesn't work disable the sound and invest in that surround sound system (external speakers solution of your choice)

try this.for first unplug the main power cord of the tv for couple of minutes and then reconnect it.also before reconnecting the power cord of the tv again remove all the external device wires connected at its back such as dvd player/vcr etc etc.just connect only tv wire and check out.if still the same problem then its quite possible that the capacitors and ic on the audio circuit board are getting short in between so the circuit is not getting completed and cutting in between so the tv starts and turns off. if the tv is connected to externalk speakers then check out without connecting the external speakers and see whether it works.if it works that means tv is perfect.but if tv is having inbuilt speakers that its confirm problem with inter audio circuit of try connecting external speakers at the back of tv and check out.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

I have connected my new surround sound to the dvd player as everything else runs through it. Also found that it has a seperate switch for 5.1 surround sound (all the speakers active) and ordinary stereo. I'm unfamiliar with yours, but check for this switch, mine was hidden on the back of the base speaker.

Hope this helps

No sound

Look in the menus for a setting to turn the speakers on and off. Make sure there isn't a switch on the back to turn off the internal speakers.

Most sets include an option to turn off the speakers. Check through your menus and see if they got turned off by mistake.
