Title: Samsung WS32A16D - Power ?
Post by: Turnip on June 11, 2010,12:09:28

Hi folks,

Have one of these where set only powers up when warm, otherwise sits in S/by. Have checked ESR on all secondary caps (OK) but general heat does the biz, but not in any localised area.

Any thoughts, as my freezer can is getting light  ?  - Chris.

hi turnip.
check regulators on logik and audoi video boards whith scope and capisitors next to them.
most of time you will find a big ripple that drop the dc voltage.
