Title: LG M227WDP - No go or S/by Led.
Post by: Turnip on July 16, 2017,12:45:33

Hi folks,

Got one in where P/S secondaries are 5v and 15v -  S/by Led doesn't light.

Have a SSB feeling - Any thoughts ? - Thanks - Chris.

Hi Chris,

Don't know, but just for the halibut I've uploaded the service manual. Schematics are as per usual somewhat disjointed, but it may help.

On the other hand, it might be an opportunity to hone your cooking skills (when SWMBO is not in residence).         Bruce

Hi Bruce,

Popped it in first thing, as SWMBO out on Sunday morning biz.

This time not a winner even though board has maybe 3 x BGA devices. Set is a bit of a pain as it's a small one where both P/I and SSB are screwed into a can where you can't reach anything to measure 'till taken apart.

Thanks for the manual - Could be one of those SSB regulators I need take it apart again to get to - Many thanks - Chris.
