Hi folks,

No-one has said yet anything about this 'common prob' before, so not yet listed on Quuq

Keep up input folks, or we'll slap you around - well, a little bit  - Chris

Hi 
List of parts that usually need replacing
F901 - T5A 20mm fuse

IC904 - STR-T2268 (cracks and sometimes blows to bits )

C920 - 220nF SMD capacitor

C921 - 4.7uF SMD capacitor

C924 - 1uF SMD capacitor

R920 - 330R SMD resistor

ZD911 - 1N5226B 3.3V zener diode

 Power supply failure is very common on this model, normally a loud bang will be heard and there after the set will be stuck in standby or be completely dead. The SMD capacitors fails and blows other components which are listed above
