Hi,
I am a noob and have no electronic background beside those high school courses. I don't know how to read the schematic but I know the principle of resistors, transistor and capacitor. I have a Pioneer vsx-1021K which I bought new 8 years ago. Last week I was careless and shorted the center speaker wires, no smoke or anything. The MCACC light is flashing after that. So I read through this forum and watched Youtube videos, I managed locate the shorted transistor 2sb1560 (part# J5032390Y0000-IL) and 2 bad resistors 0R47 (part# N113136647820-IL). After cutting them out, I put the received into the release mode “simultaneously hold Tune down arrow + multi-zone on/off for 5s” and now it is on and working again without center speaker of course. I have the service manual and found the part numbers. I went to pioneer website but they don't have it. The pioneer website referred me to pacparts.com but it doesn't have those parts either. I am stuck. Can you guys help me to find the equivalent parts? I went to digikey.com to search for the bad resistors 0R47, the result is so many when selecting “Through Hole Resistors” type. I need the following parts (you can see the picture equivalent)
1. Resistor N113136647820-IL (these 2 are bad, they don't have out any om when measuring, I need 2 of them)
2. Transistor J5011560Y0000-IL (small one) (I need 1, not sure if I need to replace this one or not because it is doesn't give me the beep)
3. Semi, TR/GE NPN 2SC J502396400010-IL (2sd2390) (I need 1, this one is ok since this forum said vsx 1021K is class B AMP, I better replace these transistors in pair because of the bad one 2sb1560)
4. Transistor J5032390Y0000-IL (2sb1560) #1 (I need 1, this one is bad, it gives me a beep)
Also is there other related components I need to check for? Finally, how do I adjust the idle current when I am done? I know there is a nob I can adjust but I don't know how/where to put the multi-meter on the AMP board to measure?
