Question about Audio Players & Recorders
Yamaha dsp-a2070 only works on tape 2. Every other input does give a really soft sound. Once the input is on tape 2 I can change source with the input selector without loosing sound.

The easiest way is to buy the new part online and replace it - cost about $50US.
However, if you're up to it, this problem is fixable without the need to buy any parts. The selector switch has four sets of spring contacts which need to be bent slightly to increase the pressure on the pads against which they press, but it's a tedious job and not for the faint-hearted.
Here's what you need to do:
Open the case (6 screws) and also free up the front panel (9 screws).
You'll see that the switch consists of a PCB, an aluminium box and a motor. Remove the two screws holding it to the front bulkhead. take oyr the small "L" shaped circuit board that overlays it. A plastic pop-in holds the bottom of the switch PCB and the switch assembly can then be removed entirely.
Next you will need to remove the aluminium switch box from the PCB. Firstly de-solder all the connections which hold it in place. Now pull it clear.
Here is the MOST critical part of the job: inside the switch box you'll see four circular plastic wafers - these contain the contacts you need to fix and you'll need to bend the tangs which hold the shaft assembly onto the housing and then the tags which are holding the wafers in place. Your difficulty will be making sure that the wafers go back on the shaft with the rightr alignment and that the wafers go back in the same order.
Take some digital pictures while the wafers are still on the shaft with the orientation of the KNOB included - if you mess this up (I did) the job becomes horrible! Also, mark each wafer with a number 1-4 because there are three different kinds Once you are comfortable that you can replace the wafers in the proper rotary configration with respect to the shaft, remove them individually and pop out the gray plastic cores and bend the spring contacts upwards so that they will go back pressing more firmly against the pads. Now reassemble, and good luck!

Probably selector switch when you turn to CD mode. The ball bearings inside the switch make poor connection resulting in intermitant problems to either speaker. Yamaha knows the selector switch is defective but has stayed silent. I've had mine replaced for $144.00 Can and it works AOK now. Different switch of course. I've had my problems with that switch for a long time and it was after a few years that a knowledgeable technician knew of the problem. Poor support by Yamaha! I'll never buy a Yamaha product again nor will my relatives and friends. Do the calculations and assess whether the cost of the switch is worth the value of the receiver. I think it is worth it as the receiver when it works is excellent. It is at a stage now when other problems could creep in though including corrosion on the boards and solder joints so have the technicians do a entire quality check at the same time...

SOURCE: hi. my YAMAHA DSP-A1000, works
The INPUT SELECTOR is defective. Order part number VT148000; it costs $51.04. As of 14 Jan 2011, the part is on backorder until the later part of Feb 2011.
Register online to order the part yourself, or you can place your order by phone at the Yamaha Parts Department at (714) 522-9011 or (888) 892-6242, Monday - Friday, 7:30 am - 5:00 pm PDT.
I hope this post also clarifies the problem from the posts above.
IMPORTANT: After installing the new Input Selector switch, place the knob at 1230 position (between LD and DAT/Tape 1) BEFORE turning the unit ON. The Yamaha Tech said this procedure ensures the input source is properly programmed and aligned.
