This may sound stupid but try this turn the volume knob to high and low continously for a few seconds sometimes the contacts become dirty and just a little movement back and forth quickly repairs it. I said SOMETIMES.

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!!

My Sony Trinitron volume goes from mute (1 bar) to loud (2 bars) - can increase to even louder but can't get low or medium volumes. The lowest volume is too loud for normal viewing. Any ideas about what I...


Hello
If you have some idea about the working of your TV, and some service experience you can do it by yourself. Your TV has electronic volume controls. That means, a gradual voltage rise or lower does the volume to go up or down. This voltage variation is done by an Ic which we call it as "System Control Ic", that every modern TV has; but differ in their type and number. You must know how to follow the schematic diagram of your tv to get the exact point from which the voltage orginates, and which point regulates the same.
At present there is some voltage, say 0.23VDC or so, remains at that control point even if you turned all the visual controls seem to be off; and that voltage suddenly goes up; say 3.05VDC or so when you adjust the volume to the near mid stage. Further saying 3.05VDC must come only after you have turned the volume bar to extreme high. Now you are listning your tv at is 1/4th volume at extreme low I thinks.
Looking for fault at system contol section must be done with patience, and should have schematic diagram of it, and some sort of skill. It is best for you to get service of an experienced service personal, otherwise the the faults will be rise in numbers. All sony tv has complex schematics even go to pages on a book, and have some difficut to follow even an experienced one you know. So think a little better and do the needy.
If you have confidence that you can reach the the above said points, contact me at my mail address which is given below. I will guide you. You must have the schematic digram of your tv also beside you. Ok.

Have you used the remote that came with the TV to raise the volume? Often, when there is more than one remote, one of them is set too low and all you need to do is use the remote that came with the TV to raise the volume level. Good Luck!

Volume is very low


Use the satellite receiver remote control to adjust the volume first. The receiver itself offers volume control and you probably have that turned down. Then you are trying to raise it with the volume control on the TV. This is raising the TV volume, but there isn't much sound there in the first place. Use the receiver remote, and you will probably see a volume bar. At some point it might say something like "best stereo" or a star might appear. If that happens leave the volume set there, otherwise just raise it all the way. Then control the volume with the TV remote, or program the DirecTV remote for your brand of TV, and the volume button should control the TV then.

Too loud


I am assuming you do not have a "surround sound" system hooked up to your digital cable box, and that you have your TV volume turned down all the way and have not yet tried to adjust the volume on your new digital cable box. It might be worth a try to unplug your TV for about 15 seconds and try again. If the above is true and you can still not lower the volume through the cable box or the TV set, then I would have the cable people stop by to check it out.
