Did mine years back - need to find part RV1802 1-418-773-11 ENCODER, ROTARY (MASTER VOLUME)
Volume went up and down turning in one direction. About 2 hour job, pull both knobs off, remove cover and front plate to get to volume switch assembly, replacement part requires desoldering and solder on new part.
hi, make sure the face pins are clean; try resetting the unit; check to see if the feel of the down switch is the same as the up switch....if not then your down switch is faulty and needs to be replaced. confirm the volume down operation by using the remote control (if available), if it works then your problem lies with the switch or a broken connection between the switch pins and the face control circuit. cheers.
A tube amp may take minute or two to warm up the vacuum tubes. Use CRC226 into the volume controls thru the little slot where the leads go into the pots. The pot may have been worn out and require replacement.
You've got a loose wire! What's happening is that there's a bad potentiometer (the electrical component behind the knob) that's out of place and is only connecting fully at one point in the knobs circuit (the part where you get full volume) take it in to an amp tech at your local music store and they'll fix it up easily.
there is a service bulletin about this. the steering wheel has to be removed along with the switch gear. then the steering shaft ring that makes contact for these controls while the wheel is being turned need to be gently dimpled to make better contact. if the dimples are too extremem the whole steering column will need replaced.
1. The volume up button on the remote may be stuck down- try wiggling the button to get it out. If it isn't the remote if the local volume control is in fact two buttons perhaps that one is stuck in or damaged.
2. The dvd sounds like it needs a new laser unit- a worn laser unit may play up like this. It might be time for a new one as replacement can be sometimes more than the cost of a new one nowdays!
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.
