SOURCE: av amplifier

The display problem is because the solderings on the back of the display are broken. To fix it you have to open the amp and redo the solderings (there are about 50 or 60 of them). There is a Youtube video that shows how to do it. I have fixed this on my DSP-A1.
I also have the problem with the motorized volume control. I have tried cleaning it, and it works for a few days, then it's stuck again. I guess I will have to replace it to have it fixed permanently. The part number is VZ621400, a new one costs about 40$.

You might have your speakers shorted. Check the wiring at the amp and speaker terminals

What is the replacement of transistor d1915


IS that a 2SD1915 or something else, it looks like an 2SA1022 or NTE2407crosses - Newark Electronics or Mouser might be able to provide you a different cross reference. There are data sheets that seem to indicate a A1022 / NTE 2407 - this one can be found here http://www.mouser.com/Search/Refine.aspx?Keyword=2SA1022 Amplifier Transistor - these are common I think for older amplifiers. If memory serves me right - I probably have a couple old ones I bought to fix a Reel to Reel .

The sound of the LEFT MAIN Cannel disappears on my YAMAHA DSP AX-1


The fact that sound appears at max volume means that it is getting past and through the pre-amp stage. So it would appear to be in the main power amp stage the problem. It would depend what drives the channel, but if it's transistor driven I would suspect one of them.

Yamaha receiver RXV-1400 turning off after 3 seconds.


Hi
there are several reasons, but the most common is because a high power trasistor is shorted, most yamaha receivers use the same names for the failure signals, such as PRD, PRI, PRY
The PRI is the signal that "tells" to the microprocessor that something is wrong with the power amplifier stage. so my recommendation is that look with the ohmeter a power transistor shorted usually if one if damaged, the next one or complimentary is too, there is a small transistor between the two big ones, usually is the number is D1915, if this is damaged, USE the SAME, also look for resistors damaged, specially the low value like the big white this resistor is 2 in 1 and some times just one resistor opens.

I hope this helps
