Hi all,
I recently purchased 2 faulty Samsung 2253BW monitor with the aim of fixing them both seeing as i successfully repaired my Samsung 19" TV. I've successfully repaired one of the 2253BW already by replacing the fuse (F301) and bad caps (C301 & C302) but i'm having trouble with the other one.
So far i've replaced:
C301 (820uf 25v)
C302 (820uf 25v)
C108 (820uf 25v)
C112 (820uf 25v)
C115 (1000uf 16v)
C116 (1000uf 16v)
C119 (330uf 10v)
C107 (47uf 50v)
F301 (125v 4a)
But still the screen comes on for 2 seconds and then off. Also, there is a high pitched noise which changes when the screen is switched off and on. Seems to be coming from around LF101 (near the power plug). Not sure if this is a red herring tho.
I know the screen panel is good as I've used a good power board on it and it displays fine.
Picture of the power board below:
Any suggestions welcomed.
Thanks for you replies in advanced.
Cheers
Adam
