Was on hardware secret's Brazillian affiliate when I found this article. I won't spoil the details, but let's just say that these PSUs weren't exactly new...

Yes, in fact, it is.Comment

Re: Braview PSU fraud.
There's also some reviews of the higher-end sunpro/leadman stuff. Did anyone else know that Leadman could do modular?

Re: Braview PSU fraud.
Wow. Terrible job doing rework there.
On the other hand on clubedohardware i found the datasheet for the famous ATX2005 chip always found in deer/solytech psu's.

Re: Braview PSU fraud.
After a little more digging on the site, I managed to find this: http://www.sunpro.cn/newEbiz1/EbizPo...=1280883815099
Sadly no internal shots, but might clear up the OEMs of those clear Logisys and Apevia units.Comment

Re: Braview PSU fraud.
Those ones aren't leadman. Those are sunpro's. I don't really know if sunpro and leadman are in bed together, or if they are two seperate companies. I think they are kind of both. Different designs, different components, but still owned (or one owns the other) by one company. Many leadman products share the KY-XXXATX part numbers that sunpro has. Remeber that powsun website kc8adu linked to a while back? It had a whole bunch of units on there with leadman model numbers and very leadman-ish design and build quality. Maybe Powmax (leadman's own brand) and Sunpro combined to make this company? Pow from powmax + sun from sunpro = Powsun.
Powsun has a psu that looks identical to this one in every way, shape, and form. Now, it may be powsun and KK are one in the same, or someone copied someone else's design.Last edited by 370forlife; 08-03-2010, 07:23 PM.Comment

Re: Braview PSU fraud.
Your link goes nowhere. Surprised they're both different companies, considering the designs are usually so similar...Comment

Re: Braview PSU fraud.
When I saw the overall look of those PSUs I though they weren't that bad. Then I saw the "rework" on the next pageOriginally posted by cheese007
.
As for Powmax, Leadman, Sun Pro, etc. - don't know if they are related not, but don't care that much either. They just make crap PSUs, that's all everyone needs to know.
Thanks alot man, I've been looking for that data sheet. Guess I didn't look hard enough. I do have a L&C PSUs that uses it. Wonder if it's similar to the chips marked with 2003 (ATX 2003??) - I have one with that as well.Originally posted by 370forlifeLast edited by momaka; 08-03-2010, 08:56 PM.Comment

Re: Braview PSU fraud.
Well, in all truth/fairness, that resistor *is* on the gate of the FET (the "control" leg; the other two are hooked up to the "power" side, source to + and drain to -), so it might actually do some good there (limiting the switching speed, slightly). I'm guessing it's just a cheap method to "cheap out" on circuit or pcb design

Patient is a Maytag/Whirlpool/Kenmore clothes dryer. Not sure of exact model, doesn't matter. All boards are out of production.
Specific problem is a Maytag 8544799 / WP8544799 motor-control board, aka Diehl Controls 708879-05. Customer states the board "doesn't work, motor doesn't run". Not sure how the repairman made that assessment, or if it's even accurate. He can't get replacement boards, and the owner decided to buy a new dryer, so whether this board is the problem is speculation on his part. Again, doesn't matter.
I've been over the board looking for... -

I was looking for specs on some OST electrolytics and tried the link to OST's capacitor page available on Badcaps, and widely available elsewhere but it came back dead. Shortening the URL a bit, I landed on OST's main site. No headings for electronic components manufacturing were displayed but I finally found this:

I'm working on one of the PSU's in my backlog today that came out of an NBA Jam arcade machine a year or so ago. The PSU is a Pan Yes brand with a model number PY-TV-C. From what I remember the 12v rail wasn't outputting anything. I opened it up and was reminded that the resistor at R28 had blown it's shell off and I have no idea how to ID a replacement for it. (see pictures) The color bands that are still intact a little are brown, black, missing band/bands, and what I'm assuming is silver. When I check it with my DMM it's reading 100ohms exactly but I don't know if that's what it's supposed...

Hi guys, this is my first post here so thanks for reading. Hopefully you all might have come across this issue before. first let me apologize for the length of the post but if you are to help me then it warrants giving you as much detail as possible, right?
So, I'm trying to bring back to life my Sony XBR-55X930D. Here is the situation: Removed and sent out power board for repair (due to no LED, red or otherwise, good power brick putting out the required 24V)). First time the board came back it did not work so I bitched at the place, mostly for not wanting to identify the parts...
