Question about Sharp 25R-S100 25" TV

1 Answer

Speaker squeal I have an amazingly LOUD squeal coming from the left speaker only. When I turn the volume down completely the squeal is unchanged. How can I fix this? If this cannot be fixed, can I just go in and disconnect this speaker? I could then change the setting to mono or just run the sound through my stereo. Currently running it to the stereo does not turn off the sound at the TV, I tried that to just work around the problem.

Re: speaker squeal

Ok if you dont wanna replace the audio output ic in this set you can simply disconnect the speakers in the set but tape them up so they wont short out against anything and then you can run the sound into your sound system of choice if it has an audio outputjack

I am having problems with our daughter's tv. The volume isnt working now even though the picture is fine?

Have you looked at the headphone jack? Sometimes a set is left plugged in and sound wil not come out of speakers.

Also, look at cable box. It can sometimes have a separate volume control.

last, if you plug in a set of headphones and you hear sound, pick up a pair of inexpensive powered speakers and use those.

No audio,tried menu items and selections,nothing.The sound just went out,what do you think it might be?

There is no sound or low volume coming from the television speakers.
Solution Follow this procedure to troubleshoot when there is no sound or low volume coming from the television.

NOTE: Because each of these steps represents a possible solution to this issue, check the television status after completing each step.
Increase the volume of the television. Ensure the television audio has not been muted. Ensure no headphones are not connected to the television. If using a set-top box with a volume control, increase the volume of the set-top box.
NOTE: If the set-top box is connected using an Audio/Video (A/V) connection, ensure that the A/V cables are connected securely to the appropriate video input on the television.
Verify that the MTS settings of the television are set to MAIN or STEREO .
NOTE: If the source device is not set to stereo or is not capable of transmitting a stereo signal, sound may come from one speaker on the TV only, and the volume will sound low. In this case, adjust or replace the source device.
If the TV has a Simulated effect in the audio menu, turn it off . Ensure the televisions speakers are not set as the center speaker.
NOTE: Some televisions allow the televisions speakers to act as the center channel speaker when using a multi-channel receiver.
Verify that the speakers are set to ON in the television menu.
IMPORTANT: If the television has audio output jacks and they are connected to a stereo system, then the speakers on the television may be turned off. Some televisions require the internal speakers or the center speaker setting to be off before audio can be sent out to a stereo receiver via the audio out jacks.
Ensure all audio and video cable connections are properly connected to the television.
Test the television using another source like a VCR, DVD player or Blu-ray Disc™ (BD) player.
Reset the television to the original factory settings. To reset your TV to factory settings, turn the TV ON. Then, while pressing the UP ARROW button on the Remote Control, press the POWER button on the TV. The TV will turn itself OFF then back ON.
NOTE: If your remote control does not have a RESET button or the procedure did not reset the TV to the factory default settings, perform a power reset.
If the issue is still unresolved after completing all the troubleshooting steps suggested, service may be required.

After tv is on for approx 20-30 mins it starts to make a loud high pitched squeal or whine. once turned off for approx 10-15 mins can turn it back on for another 20-30 mins before squeal will return....

Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00

Philips tv with sound going in and out

Try bypassing the set's speaker by running an external audio amp. I use my bookcase stereo for audio direct from the satellite receiver and turn the volume off on the TV. Sounds better this way! Could be the audio amp in the TV is going bad or the speaker may be bad and the TV's audio amp goes through a shut down cycle.

Won't turn on - relay clicks, power supply squeals, relay clicks, etc,

The television has a protection circuit. Sound like you know something about electronics so that is cool.

I suspect the HOT or High Voltage Transformer. If you want to operate on it, they typically will short externally from moisture or plastic high voltage breakdown. The TV starts, shorts as it cannot come to full high voltage, then shuts down. If your brave, you can unsolder the HOT which is the part that is on the main board or that comes from the top of the picture tube wire into a dark or spaceship type object.look underneath, sometimes they short underneath and you can scrap the carbon and get it to at least start up and work. Do not leave this as a fix as it can be a fire hazard.

The HOT is the most common. They are around 20-60 bucks. 34" TV. I am assuming this one without looking it up it is NOT a flat screen, as most do not squeal like that nor do they have to de-gausse like the old ones. I just looked it up and yes it is not a flat screen. Old school, so that is more thank likely the problem.

Sound problems

I have had the identical problem from the beginning. It happens in humid weather. Unplug the set while it's on, wait a second, plug it back in, and turn it on. Sound should be fine.

Buzzing after 1 hour

Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?
