car cd player system board help

[Guest]

i was trying to fix the pico fuse on my PIONEER DEH-P880PRS cd player. while trying to fix this. i knocked of two components on the system board. i don't know if they were fuses or what. They did have the numbers "473" on one and "222".

they were also tiny, so small that i can't find them anymore. does anyone know what they are, or can point me to a better reference on circuit boards? thx

(the cd player, will not turn on. it gets power b/c you can hear the little actuator/ cd release mechanism move inside, but nothing else)

Do not have a schematic but, based on your description on the devices, sounds like SMD resistors that were broken off the pcb. Last digit denotes the number of zeros
473= 47000 ohms or 4.7K
222= 2200 ohms or 2.2 k
