Volume automatically goes to maximum

When I turn on my SONY KV27FV300 TV, the volume automatically goes to the maximum. It can be lowered using the doen volume button, but once the button is released, it goes back to the maximum.

The tv is not responding to the remote and will not allow the reset to factory settings. I unplugged for 2 days, problem still occurs.

Any ideas??

    Dan,

    Thanks but that did not work. Each button was able to push in and out freely. I could tell they were 'not stuck' as they clearly pushed in and out easily.



    Any other thoughts?

    Keep me posted Dan, thanks.

    I kept it unplugged for a week and now it works.



    Thanks!

This sounds like there is a stuck button. With the TV off, try each of the panel buttons. You should feel the button engage. If not, that is the faulty one that should be replaced. Also, check to be sure that the plastic covering that extends to the actual switch inside the set is not broken causing a switch to be stuck on.
Keep us posted.

    There are two other possibilities that I have seen in the past:

    1) The volume control chip is defective (not likely as the vol changes both up and down)

    2) The control IC is defective and is constantly telling the voume chip to increase volume.



    I'll look up this model and post the specifics.

My volume on my sony tv wont go past 12 it will higher and lower but the maximum it will higher to is 12 have i maybe put a volume lock on it??


The only way the volume could be limited is if you were in the hidden tech menu----many of these sets have a setting there for initial volume level and maximum volume level.

Were you in the TECH menu for some reason?

I can tell you how to get in but you have to be very careful if you make any ADJUSTMENTS there--over 200 things can be adjusted there.

Let me know if I can help.

Volume automatically goes to maximum on TCL TV


The volume (+) button on the TV is stuck or soiled if the volume automatically increases when the TV is turned on. To find out:
  1. Turn off the TV.
  2. Press and hold the volume (-) button on the TV then turn it on.
  3. If the volume doesn't automatically increase, you have a stuck button.
  4. If it does increase, you have a faulty key control board.
  5. In either case, you have to replace the key control board.
To find it out further:
Warning: Beware of electric shock.Please do not proceed if you do not have the skill to do the following.
  1. Unplug the TV.
  2. Let it stand for 15 minutes to allow voltages to drain completely to avoid the risk of electric shock.
  3. Remove the screws securing the TV's back cover and pull it off.
  4. Disconnect the cable that runs from the main board to the control key board.
  5. Turn the TV on using the remote.
  6. In this manner you can use the remote control to run the TV while waiting for the control key replacement board.
To do a hard reset of the TV, unplug it and let it sit for 2 hours or long enough to completely drain the internal voltages.

Sound


Set your SAT receiver to full volume and use your Sony TV volume control as the master volume control. If you use an external surround sound amplifier do the same thing using the amplifiers volume control as the master volume control.

Consider that all source devices that have the ability to control their output volume will output what they call line level 0dB when the source device is set for maximum volume. If you set the source device to 1/4 volume your output to the amplifier may be around -25dB or lower. Introduce that low of an audio level to the amp and you will have to turn the amp up to half way or better causing the amp to amplify noise too.

Low volume on playback


The volume control on the TV does not affect the recording. However, if you were recording from a set top box, and you turned the volume down on the box and not the TV, then this would cause the problem you describe.

If this is the case, then try to keep the STB volume at maximum and only use the TV volume control.

Also, some DVD players and VCRs have a lower output than the standard TV tuner, so an increase in volume is usually needed.

You might want to try some test recordings to see what happens.
