Re: Samsung 740n no backlight after cap replacement


i dont think the backlight worked before i replaced them.

sorry, im a total amateur... i dont really know how to check CN2 and i dont have a multimeter at the moment.

"BIT3195G F343R G0606" is written on the IC...

Re: Samsung 740n no backlight after cap replacement

i found the white/pink & black/green image on google, its just to show which cables im talking about.
but here are the pics of my board (sorry lol .. as i said im new here )
i dont have a multimeter right now but i'll try to get one today to check the fuse

any other pictures needed?...

hey guys, this is my first post in this forum so i hope im doing everything right

so i hava a Samsung Syncmaster 740n that stopped working properly (blue led was on but no picture)
i did a little reserch and found out that the three 820mf 25v capacitors on the power board were bad, it took a while but i eventualy found a store that sells 820mf 25v caps, i bought them and replaced the caps.
when i tested it out (before reassembling the plastic casing) i could see that the lcd was working, however the backlight was not.

what do think the problem is? and how...
