The intrenal switch that controls the volume up is shorted. you need to have it replaced. the short of the switch doesn't allow any other buttons on the set to work because the micro is recieving the volume up command. it's as if there is an invisible finger pushing the volume up button. the switch is a tachtile switch which is very inexpencive to repair about $50.00 total. if you want to do the repair yourself be aware there are voltages that remain in the set that can be harmful. 50% of the time the cause of these switches shorting is improper screen cleaning. some people spray glass cleaner directly on the screen, this is bad. the cleaner drips into the set and lands on the PC board where the buttons are housed. but I've seen the other 50% also which is hummidity, dust(not anyones fault this just happens), and simple switch failure. so becareful repairing it your self

Volume modulates but is too low on max


Are you turning up on the tv itself? If you have a cable box, there is a separate volume that needs to be turned up too!!

Tv volume stuck on max, volume + signal stuck, button is fine.


The problem is on the board with the controls----if remote receiver is not on same board disconnect that board--if it is unsolder the vol and channel buttons--the front buttons have priority over the remote--buttons will look fine but the switch under each will be your problem---better hope it is as only other cause is a microprocessor gone mad.

If you have a Ohm meter I can tell you how to prove this--going to have to get at the buttons--if you want to prove it is or is not a issue with the micro switches you are going to have to unsolder or test them.

My volume button goes all the way up to the max and stays there and sometimes my mute won't work how do i fix the problem


It looks as if your volume up button is stuck, either on the TVs manual buttons or the volume up button from the remote. To check if it's the remote, put the remote away from the TV, either in a drawer or take the batteries out. If the same check the Volume up button on the TV, it may be pressed down & stuck in this position. If this is ok most likely the volume button will be at fault & need replaced.

"snow" screen, full volume, remotes don"t work


good day
due to the long time the buttons were not used, they tend to get stuck and this causes channels eighter to stay in one station or continou scanning. it could be resolved by spraying WD40 on the buttons and press it many times then dry it before operating the unit.

Volume go up to MAX, power button does not work


To all of you, change the tact switches (all of them) on the front panel control board and end of problem, very common problem, part number for these switches is 23344443, any or several will become "leaky" and give all sorts of symptoms, MANY times this is caused by using windex or similiar type cleaners, it gets into the switches and corrupts them, this will fix-ya, BMW Rider

Volume Issues with Television


toshiba 35a44 I had in shop would not turn on initially,when Qa01 was replaced I was able to turn tv on, but after a couple of minutes volume went all the way down, vol display bar on screen and power and menu keys would not work, remote control function did not mater. after replacement of QA02 mpu no results. desoldered volume down and up keys and sprayed chassis with flux remover on both sides of chassis and sumerged vol keys in alcohol solutions for 10 minutes, restored them in chassis and the problem was corrected. QA01 and QA02 did not had to be replaced there was a contaminant problem on solder flux that was causing the problem. kbzon

Volume gone mad


Is there a ceiling fan in the same room? Under the right conditions, light reflecting off the whirling blades hits the TVs sensor at just the right frequency, causing mysterious things like this. Try covering the infrared sensor on the TV (it should be behind a red transparent piece of plastic somewhere in the front. If this keeps it from "going mad", then something in the room is to blame. If it still does it even when the sensor is covered, then it is the TV. Good luck, and let us know what you find!

Sony 36' TV Volume Goes up on own/Stuck on Video 2


There's a setting in the menu. I think it's called "smart audio". It's supposed to adjust the volume automatically for commercials. But I don't think it works that well. Give that a try.
