Re: Samsung 2253BW - 2 Sec to Black issue

I've managed to get a STM8309, its on its way.

Looks like its going to be very difficult to swap this out, its so tiny !

Re: Samsung 2253BW - 2 Sec to Black issue

I'm trying to match up a replacement MOSFET but i'm not sure which one....

I've filtered the required spec according to the spec sheet and got it down to 2, but which one ? Of course these might not be compatible.

Or these 2: [url]http://uk.rs-online.com/web/c/semiconductors/discrete-semiconductors/mosfet-transistors/?sort-by=default&sort-order=default&applied-dimensions=4294509285,%204294481421,%204294512079,%204294499258,4294510975&lastAttributeSelectedBlock=4294957828[/url]...

Re: Samsung 2253BW - 2 Sec to Black issue

Actually, the only one that has a off reading compared to the others is the 2nd chip and S2 to G2, its reading is 5.7

Does that look like my problem ?

Any idea of the range of read outs i should be seeing ?

S1 to D1 (both) - 341k
S2 to D2 (both) - 337k
S1 to G1 - 421k
S2 to G2 - 10k
G1 to D1 (both) - 0.815m
G2 to D2 (both) - 345kRe: Samsung 2253BW - 2 Sec to Black ...ould be seeing

Re: Samsung 2253BW - 2 Sec to Black issue

Thanks, i think it reads "STM8309 81343"

Any idea how i would go about test that component ?

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...
