Re: Overloaded Horrible Antec SmartPower SP-500 to death
Yes I know this thread is months old.
I have an SP500 which still "runs" with one of the two main filtering caps (I think it's a 200v - hard to read it) a little bulged on the top.
I use this PSU for testing mobos and such I find on the curb, even temporarily assemble non-high powered computer systems to see how well it works.
lol!
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Syncmaster 2253lw inverter "not turning on"
Thanks guys, that power supply board is not worth repairing as I found that also out one of the inverters is bad as well = comes out to too much $$ and effort and just makes no sense to me.
Cheaper for me to find a used or new working power board as eBay has some for $2x.xx shipped.

Re: Syncmaster 2253lw inverter "not turning on"
After back and forth for a couple of weeks the repair of this monitor is dead! I screwed up taking out a mosfet that it took the trace of a leg off the PCB.
I'm so ticked off!
Thanks for the help till this point - I really do appreciate it.

Re: Syncmaster 2253lw inverter "not turning on"
I replaced the fuse and now it's totally dead even though the fuse checks out before and after the installation.
Sounds like this monitor doesn't want to work for me.
Time for mosfet check.
EDIT: Okay tested the mosfets and one is shorted - fun fun fun! lol!
What would I do without a multimeter? I know, I would've given up already.Last edited by nickt1862; 05-10-2012, 09:10 AM.

Re: Syncmaster 2253lw inverter "not turning on"
Good idea for sure.
Well I have a donor one (that I just realized I had laying around) that I'll use to see what happens from an old power board of a crappy monitor which same rated fuse checks out.
If it works I'll await my next cap order to order these and with me finding things that will be soon.
Just today I repaired a 20" Samsung monitor by replacing all the caps - of course that now works fine and which I won't personally use but the 22" (2253lw)...

Re: Syncmaster 2253lw inverter "not turning on"
I know that the photo above is "lousy", but if you see that "long" green fuse by the cap on the right by the inverter in that photo is the one that failed.
Now where to get one - can't find it as maybe I'm searching wrong.
Can you please give me a suggestion? ...

Re: Syncmaster 2253lw inverter "not turning on"
Okay, today I received the caps and multimeter.
Replaced remaining caps and STILL doesn't work. All I get still is the solid blue power light.
However if I tested the fuses correctly using the multimeter one of them is no good.
The "button" fuse I tested its continuity and ohms checks out at "0" - it dropped to that.
The "longer green" fuse (125v F4 0AL) by the inverters has no continuity and the ohm number keeps on going up and up and up....

Re: Syncmaster 2253lw inverter "not turning on"
[B]Thanks! [/B]
Okay then, I shall order the DMB9.
Thanks so very much for educating me on multimeters and such as I've never used one hence the "beginner" type questions on them.
My new "problem" I'm having is finding a place that has good branded low esr 105 degree caps in these values:
2 x 10uf 50v
1 x 47uf 50v
1 x 100uf 16v
1 x 470uf 25v
2 x 1000uf 25v

Re: Syncmaster 2253lw inverter "not turning on"
Thanks sooooo much for trying to help me in acquiring a multimeter.
I may have missed this (because I'm so tired right now lol!) but I don't think this is capable to also measure capacitance.
I'd be willing to spend a tad more to have that additional feature with what the DM9B already can do unless it can do this as well.
Thanks again,
Nick...

Re: Syncmaster 2253lw inverter "not turning on"
Setting the meter to OHMS and a good fuse should read almost zero ohms.
Most people say to take the component out to test and the probes on both leads.
Now I have to work on acquiring a multimeter.
Always wanted to get one, never got around to it or had a good enough reason to get one.

Re: Syncmaster 2253lw inverter "not turning on"
retiredcaps,
Yeah replacing the rest except the 100uf 450v was my plan and it seems is what I'll do first and see what happens. Those remaining 4 are all Chinese branded garbage.
One fuse on mine is a button type 250v, T3, 15AL.
The other by the inverters is a 125v, F4, 0AL
