That might do it. But first I'll try that parallel configuration, If it fails, I do have another control board and a case to use with toroidal

Re: "Upgrading" a Weller WECP-20?
well, does that have 5V tap? Those amps should be the same, so parallel could cut it? Tho I'd need to make a new chassis for that combo ;DLast edited by DMCrimson; 04-27-2014, 03:55 PM.Leave a comment:

Re: "Upgrading" a Weller WECP-20?
Just a thought: I do have a second WECP-20 unit - could I just use the transformer from that and use them two in parallel? They would then share the load, methinks. Someone wiser, put a word

Re: "Upgrading" a Weller WECP-20?
Ooops, my bad for not being clear enough... I'm running a WSP80 with WECP-20, which is a 50VA thingy. And if I push temp over 350 °C it starts chirping a bit

Re: "Upgrading" a Weller WECP-20?
Looks like I need to do a comparison on the pcb against that. Any info on the transformer?Leave a comment:

Re: "Upgrading" a Weller WECP-20?
Anyone with PU80? care to pop it open and check part number on controller pcb and trans? Pictures would be cool too

Re: "Upgrading" a Weller WECP-20?
Hehe, finally got around to do this, though I didn't have a drill to work with. Just plain soldering iron, with some stiff copper wire wrapped on it - on I went. The transformer indeed does hum a bit, and stops at some point, but this could be that I had just WP80 to go with. Overall - satisfied. Still need to try and source that transformer Gosh year and a half

Re: Benq 24" monitor cracked screen
I'd dare say it's worth it, but you should do it yourself. That is, if you can source the screen from somewhere...Leave a comment:

Re: Repairing a FujitsuSiemens LSL3230T
Hmm... wc_robot has srf10150 where I have srf10-20. That's weird. Also, I remeasured that 10-20 and it seems shot - dmm shows 0,002V for forward voltage.Leave a comment:

Re: Repairing a FujitsuSiemens LSL3230T
Now, are there any suitable replacements for those Schottky's mentioned, SRF10-10 and SRF10-20? Also, that MOSFET, AP2761P-A? Just on the safe side for the future...Leave a comment:

Re: Repairing a FujitsuSiemens LSL3230T
I've beem unable to do a thing on this. We moved recently and subsequently filed for divorce... Currently I'm trying to study at TUAS, but not on full power as I have both depression and panic attacks. I just hope I get my own apartment, then I think I can focus on these things better.Leave a comment:

Re: Repairing a FujitsuSiemens LSL3230T
Thanks Rtech. I'll need to check the diodes (did you mean those 1N4148's I already changed?) and the mosfet - thanks for pointers
wc_robot: There's an ongoing auction @ ebay, which has suitable board - I think that might be for you: [url]http://www.ebay.com/itm/Hannspree-HF23-Parts/390450714134?ssPageName=WDVW&rd=1&ih=026&category=168068&cmd=ViewItem[/url] as the seller will only ship to states.Re: Repairing a FujitsuSiemens LSL32...you mean thoseLeave a comment:

Re: Repaired a Benq G2110WA - with duct tape
The adapter arrived, but I'm no too satisfied. The picture looks a bit fuzzy... I just cannot help but wonder if I could hack this PSU into my dead fujitsu...Leave a comment:

Re: Repaired a Benq G2110WA - with duct tape
Hehe, forgot totally about that. The monitor isn't on use currently, due to lack of DVI to VGA adapter... Duh. Will take a few weeks to get here. ordered one from DX yesterday.Last edited by DMCrimson; 07-18-2012, 01:18 AM.Leave a comment:

Re: How to get to the backlights in CMV221A?
The metal case is held together by small tabs, as you can see from the latter image. Carefully pry them open, working your way around the case.Leave a comment:

Repaired a Benq G2110WA - with duct tape:D
Well, another dump find - asked the girl that brought it there what's wrong, and she told me that the power button doesn't work. Cracked the case open and the red plastic that acts as power button had separated itself from the black plastic of the bezel. Tiny strip of duct tape, and the case is closed.
Silly thing to use two tiny blobs of melt in order to attach a heavily used button... -
Re: Repairing a FujitsuSiemens LSL3230T
Could it be the feedback via opto? My neighbour told me the monitor ceased working all of sudden with no warning at all.Leave a comment:

Re: Repairing a FujitsuSiemens LSL3230T
Primary side (AC) has 4 pins
measurements:
1-2: 0,2 ohm
1-3: ~5 Mohm
1-4: ~5 Mohm
2-3: ~5 Mohm
2-4: ~5 Mohm
3-4: 0 ohm
secondary side has 6 pins, but can be treated as 3 pins as they're soldered in groups of two:
zero all around.Leave a comment:
