Hi Folks,

Note there have been several mails over the years about this set not firing up although S/by 5v was present.

Seems main board needs to switch PS relay to connect mains input to main, mains bridge recifier.

Had one in today with the usual problem where S/by 5v is present, but set won't turn on, and there are no obvious faults in the main power sector.

Wonder if anyone has yet sussed it.

Note - Another site has restricted (possible) solutions to this problem - Chris

Hi Chris,

My notes say the main smoothing block is quite often o/c, and check all other electrolytics.

Hi Keith, and thanks,

This one came in after cust reported loss of DVB channels, where a retune initially did the biz. Next time it was no go with S/by supply present, so was naturally suspicious of the Main board.

Power/Inverter seemed OK, so replacement Main ordered from Fleabay.

Checked M/cap and reads a little less than stated 300Mfd (284Mfd) with an ESR of 0,25 Ohms, so could be a prob - will advise after panel replacement.

Thanks again - Chris.

PS - As to the other caps, board looked so pristine with nothing brown or bulgy, so didn't bother - could be a mistake. Note that several other Quuq'ers have had a similar problem over the years, so guess it's not particularly unusual but no-one yet has given a 'Quuq' solution.
