Re: Samsung 2253LW
I've lost my multimeter so cant check.
all caps are Panasonic FC.
The start-up cap seems to have definitley worked as I didn't get blue light at all before.
Caps not replaced:
Far side:
2x 820uf 25v
1x 16v 100uf
Inverter side:
2x 16v 1000uf
1x 50v 10uf
1x 10v 33uf
the massive cap - think its a 100uf 450v but the label is against the PCB and dont want to move it really.
everything looks OK, no bulging or puffing. all original caps...Last edited by ab101; 05-15-2012, 06:58 AM.Leave a comment:

Re: Samsung 2253LW
After swapping the 2 820uf 25v I still got nothing and realised the 47uf 50v cap had also blown - just swapped this out for a new one and now when I plug the monitor in the blue light slowly flashes and I hear a high pitched whistling noise - the back-lights don't come on however and I don't see anything on the screen.
All other caps look OK - is there any more I can do or is this thing dead?...Leave a comment:

Re: Samsung 2253LW
I stupidly didn't take a pic of the whole board - I had to reassemble the monitor due to space. (phone quality) pic of capacitors attached....Leave a comment:

Samsung 2253LW
Hi,
I have a Samsung 2253LW that's been going strong for 3.5 years but the last few days randomly decides if it's going to work or not (sometimes pulling the plug out and sticking it back in will fix it, other times not).
Ive got it in pieces right now and can identify 2 bulging capacitors, both are Sam Young 25v 820uf 105 degrees - I thought it would be a straight swap but having searched the forums it looks like there are a lot of capacitors that match that description!
Could someone tell me exactly which one I need, and who in the UK sells them...
