Title: Samsung LE32R73BD
Post by: yellowpinky on September 03, 2010,03:33:11

Hello Group,
This set is dead with no led lite.
There is voltage on the primary side of the power supply but nothing on the secondary.
Has anyone a circuit for the power supply and the 5v start up supply.
The power supply is a BN96-03775A and not the one with the 1000uf bulging caps.
Many thanks Ian Harrison (Sound and Vision)

Hi folks, have nothing listed - bit embarassed -

Well folks don't always say - not all Tories these days, I guess,

Guess you'll attach loads of piccies, perhaps  - Chris.

Hello All,
I have been away for a few days and just picked up your comments.
I did suspect F9222L, but I did not know where the missing start up supply came from.
I have printed off the circuit and should pinpoint it tomorrow.
I will keep you posted.
Photo attached.
Many thanks to Daz, Turpin and Vladimir H
