Model Brilliance 181AS
Type 18L8025Q/00C
Chassis FM8000
FCCID A3KM087
Symptom: Complete failure, probably smell of burned plastic / PCB
Cause: One or more of C2909, C2936 and C2939 (100u 16V tantalum) are
shorted due to over voltage condition in suspend mode, at least in
models with IC7905 not installed. The +12V rail rises to more than
20 volts without load causing failure of the tantalum capacitors. A
4.7k resistor across this supply keeps the rail well below 14 volts.
One unit has successfully been repaired using two (instead of three)
low ESR 100u 25V aluminium electrolytic capacitors (see picture).
