    I already did that, unplugging it for the whole night but it didn't fix it.

It is possible that the TV was hit by a small power surge, and has garbage in the audio processor. You need to unplug the TV from the wall for 40 MIN, and that will reset the audio processor back to normal.

Volume increases to 100 or drops all the way to 0 when pressing the volume button on either the remote or back of the tv. I can't control the volume I want.


Keyboard issues and answers:
A problem that is more common than most people think is anissue with buttons on the controlkeyboards of modern TV sets.
Recently for whatever reason I have seen more questionsabout this so I have composed this answer and solution for these kinds ofproblems.It can be any button on the set-channel up/down or volume updown-you name it.

The symptoms are the same: channel will scan up or down andwill not stop-remote control has no effect on this---It can be channel, volume,or even input or menu if the set has those up front or on the side of the set.

All these push controls have something in common-beneatheach is a tiny momentary push switch-when pushed with the plastic button itperforms a specific task (vol up or down etc.).

What happens is the afflicted switch beneath the plasticbutton is bad-when released it is supposed to stop its function but does not.

Keyboard or button controlled features have PRIORITY over the remote control, hence the remote will not stop this fromhappening.
Both the remote and thekeyboard go to the microprocessor in the set but keyboard is first in line.

How to resolve this issue?

Someone needs to get at the tiny pc board with the buttonsand locate the one associated with the issue (ie sound or channel etc) andunsolder that switch from the board-usually just two pins (may be more formounting only purposes) and then see if set does not have the issue with switchout of the circuit.

For the TECH minded with the board out test here theswitches with a ohm meter set to high resistance-any reading with button notpressed means a bad switch-seen ones that read 5,000 plus ohms-it may benecessary to unsolder more than one switch to locate the offender here but an open reading with switch not pressed is therule.

I have taken the time to compose this answer as some do notunderstand what is happening in these types of situations---No magic wand orsmoke and mirrors here-have to disable the offending switch to know.

The beauty (in my view) of this kind of problem is if found, you really do not have to replace anypart-just operate the set with the remote with one button that no longerfunctions on the set itself-who could ask for more?

Why does the radio volume go up without turning it up?


Hello
It is an electronic component mistake in the circuit board. Even though the volume is controlled by a knob, it actually works in cnjuction with and electronci circuit, usually controlled by an IC in some sets or with a transistor with others. You have to find out the faulty component on board. It is really a skilled work. Eventhough the faulty component won't cost more, loacating it is a skilled job indeed. You must have thorough knoledge in electronics, and the schematic diagram of your set. You must have knoledge to follow the schematic diagram too. You may be pretty handy, but this is not enough find out the faulty component. Must be an expert and must have succician expereince in repairing electronic circuits. OK.

A black square pops up on the screen while watching a show. The only way for this black square to go away, is to turn up or down the volume.


Check your closed-caption settings and be sure it's turned off. Captions have gotten turned on and set to "text" mode, and the set is blanking out the area where the test would go. This often happens if someone presses the button on the remote that controls caption settings without realizing it.

9 blinks,won't turn ON, but I can make it turn on with diagnostic


I'm suprised with nine blimks the set will turn on at all. You are in the service menu; be careful, you can render the set totally unusable if you change something. Try unplugging the set for a few minutes and plug back in.

OR
Your phone's ringing volume is set to zero( 0 ). try this. go to tools folder. then profiles, select general and click personalise. scroll down to ringing volume and you can set it to its maximum volume.

I did the following 'press and hold both the "VOLUME Down" button on the TV itself and the TV/VIDEO key on the remote control simultaneously for about 7 seconds (they say over 5 seconds in the manual)"

Will in the service screen I selected the number of hours of the lamp with the down arrows and the action buttons. Then I simply pressed and held the "down volume button" on the remote until the number of hours was 0. Then I turned the TV off, then back on and the message was gone. This worked for me.
