Problem is not batteries or remote control units; the tv set turned on ok this morning, but the volume was stuck on 100; i tried to turn it down and it would not turn down; so i changed the channel off of sat-tv; now, the channels change up/down, but nothing comes on the screen except snow; the volume control does not work on the front panel either; nothing on the front panel works; i did get the set turned off by use of the remote contol with sat-tv dish; but now the set does not even come on...when i cut the power from the tv at the power strip, the only thing that happens is the red light on the set front, near the power switch glows for a second and then goes off..........what gives? any help appreciated......Curt

It sounds like one of the volume down buttons is stuck in the activate position. The same as if you were holding the down volume button continuously. It could be either the volume down button on the TV or the remote. I would try remove the batteries of the remote then adjust the volume by the TV buttons.
If the volume doesn't go back down then the remote is the problem. In order to fix the remote you may need to take it apart. This is normally easy to do just locate any screws that may be holding the remote together. If you don't see any screws then you will need to pry the two sections apart. Separate the circuit board and rubber buttons and clean them both with some rubbing alcohol and reassemble it. If it still has the volume issue you may need to replace it.
If the problem persists with the remote deactivated then it's the volume button located on the TV. That is a little more difficult. You can try wiggling the button or some canned air (used to clean computer keyboards) to blow it clean. However it may need to be disassembled to gain access to the switches for proper cleaning. Hope this helps.
don`t know if this will work for yours but I have heard of menu coming up all by itself randomly and the fix was to remove the batteries from the cable boxes remote and the tv`s remote, partially stuck on buttons were the cause, replaced the remote end of problem, hope this helps on yours.
I had the same problem, you'll probably find that that particular button will push further into the set then the others, this is due to the a weakening of a cheesy metal guide which directs the projection off the back of the button into the corresponding microswitch. This metal guide will bend and will push against the switch.My solution, (and it ain't pretty) was to unplug the set, remove the button( I used a dremel cutting bit), locate the guide,a small metal plate with a hole in it. Bend the plate toward the front of the set then tape over the hole. I haven't had the problem since.You WILL have to use your remote for further functionality of the volume, However all of the buttons seem to be inherantly poorly designed and will weaken over time, AVOID USING THEM!
the tactile switches on the control panel cause this problem . they could'be stuck or have some kind of contamination like liquid. or just bad . cost to repair aroud 60.00 dls if this helps please let me know
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.
