Question about Amplifiers & Preamps
My Hifi turns on and all the controls work apart from one. The volume won't go up / down. When it worked the remote moved the sound dial - now it doesn't. My dad (who is a boffin) checked the insides and all parts have power as far as he can tell. I would like to get a circuit diagram so we can try to figure out which chip / component is unwell. I haven't blown the amp (honest) it just stopped working one day. It did used to go straight to clock setting when powered up but I just put in a CD and it generally worked. On some occasions I had to turn it off and on with the CD button pressed down. I should have contacted richer sounds when this first happened - doh. It's out of warranty (I got it for my 40th and I'm 43 and a bit). Any ideas would be much appreciated. BTW the beastie is at my dad's and he won't be back until the 1st Jan.
The problem could be with the remote itself. The volume buttons on remotes usually get the most use and therefore wear out. Try using a universal remote programmed for your Onkyo and see if that works.
