Question about Quasar SP-2723 27" TV
I cant get the audio on the tv to mute or turn down.although the displays shows that it is doing so.I have searched the audio section but was unable to find any shorts.. need some help!
This can happen if you hook an external amp to the audio output jacks on the TV and those jacks are set to fixed output, but I will assume that you are talking about the sound through the TV's internal speakers. If the picture is normal and the On Screen Display (OSD) shows that volume is being turned down then the microprocessor is putting out the correct clock and data commands. You need to find the audio processor IC which controls the volume, tone, balance, etc. and see if the clock and data information is actually reaching that IC. If it is then I will bet that the IC is defective and needs to be replaced. If you do not have an oscilloscope or experience in repairing PC boards then have a qualified tech handle it for you.
