hi
I am trying to restore a SONY WM D6 (sn 238913) (bought 30euros)
which seems to be 100% ok mechanically
but have simultaneaous serious issues for electronics:
- no batt level detect (always lower led on)
- most serious problem : the motor speed is 3x the normal speed
also the battery clip is no ok
could some one send me a good picture of it ?
if someone had encountered already the same king of problem , help would be appreciated !
I have an oscilloscope and the service manual
for example, I saw a proper square 34k7 on pin 3 of the ic701(osc pll)
but I have nothing on pin7 if ic601 (servo)
thanks
