Re: Sansui tv/vcr combo is stuck on highest volume.
If you have the remote,have you tried it ?
Have you tried the volume button on the front of the set ?
If neither the remote or the button will work, then you may have a problem with the microprocessor IC (system control). If this is the case, then the set might not be economical to repair.
Perhaps the volume "up" button is stuck ?
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Chances are that one of the volume buttons (either on the TV itself or on the remote) is stuck. You'll be able to know if it's the remote by taking out its batteries and trying the same process. If the issue persists, see if the volume down button on the TV is stuck and can be freed.
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.
Did you ever get this problem fixed? Ours just started doing the same thing. It worked fine the night before, but today it's doing what yours is doing. The remote stopped working for the TV. The remote still works for the cable box, but volume and anything related to TV function not. The screen flashes when we try to adjust volume or anything else, but resets to previous volume. TV not responding to any commands either on the front panel or remote.
Any ideas? Thanks, Patti
It could be several problems, I'll share with u a couple. All of them need a tech.[technician]
Your volume control works by adjusting the voltage\current to the speakers. The VOLUME CONTROL could be damaged\fixed at a point [even if you are raising\lowering] at high volume.Sometime the control has a crack ********\********* in such a way that the volume arm won't go past crack[see above] on HIGH volume.
The audio IC could be shorted in high volume. Sometimes the audio IC is PART of a 64 (sixty-four) pin ckt. How do u test for that if u are not a techo'
Let someone take a peek at it.
Aren you sure that the volume up button is not stuck in . It should feel just like the rest of them A little click? It could still be shorted,or the capacitor across the switch could be defective. If all this seems good then the eeprom, or the microprocessor,or the line or trace going to the volum button could be shorted. This is not a repair you should attempt unless your a tech. Now the button thong can be looked at after the set is unpluged and the back is off, gently slide out the chassis toward the rear of the set just a little and slide it back to see if the button is released. if that dosent help then you will need to take the set to The repair center. Good Luck
