If anyone has the Fender Passport PD-250 SMPS schematic could they please PM me? I am setting up a simulation in Multisim and I need it for that.
Thanks
Tom

Re: Fender PD-250 SMPS Schematic
Have you tried Google?
You do realise that trying to correctly simulate a full SMPS in Multisim will likely leave you literally tearing your hair out, or worse, assuming you can even get a somewhat accurate model of any inductors and transformers they use..."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

I got the components list from the repair manual but no schematic to go with it unless I am missing part of the manual.Computer and Small electronics troubleshooting and repairComment

Hello Community,
If anyone has it or can point me in the right direction, I'm after a Schematic for SMPS BN44-01056A

I am trying to find two smd datasheets for an Apevia 1000w prestige power supply ATX-PR1000W the SMD's are ST9S313 which is a SMPS supervisory chip and a EST 915HP or XP48024 not sure which or both is the chp prod number and the schematic

Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this... -
Good evening all!
I'm currently working on a Samsung UN46EH5000 TV.
I'm looking for the SMPS schematic for it. Does anyone have a source they can point me to? I looked on ElektroTanya and Tom's Service manual's sites, but i didn't see it.
I got the TV for $10. The unit worked, but 26 of the 44 back light LEDs were blown (all shorted). Looks like that is common with this model. Using my LED tester, it shows a Vf=2.6-2.7V.
I replaced all of the LEDs with SMD parts that I have. The rated Vf=2.9V on these units.
Right...
