I have a 1st Gen iPod model# M8541 with D207 burned up. Does anyone have a schematic?
Thanks a bunch!

Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor... -
this is the diode (on detachable keyboard)
burned because the customer inserted the power jack on a USB port...
anyone know what diode can be this?
2 pics on attachments
probably thesame diode can be found on miix 310 ... or 320.. but icanàt find schematics about this "new" miix tablets.... -
Hello Everyone,
I will be really grateful if someone shares schematics and if possible the boardview of the old Asus Nexus 7 (2012) Tablet. The motherboard is ME370T Rev. 2.4. Now I can find schematics for the Rev. 1.0 but I could not find the schematics for the Rev 2.4. I tried to look for similarities in the Rev. 1 but there are somethings missing, plus the board i have has nearly no component names printed on it which as a newbie makes pretty hard for me to locate things. Any assistance will be appreciated. Thank you. -
If anyone needs schematic diagrams for any pro audio gear like what professional musicians use, such as guitar amps, power amplifiers, vintage tube amps, musical gear like keyboards, effects pedals, guitar wiring diagrams and service manuals, check out https://schematics.ca . I'm a road musician and an electronics tech and I got schematics for just about every piece of gear in my band from this site and they are free to download. It's always good to be prepared in case you fry something while on on the road, which always happens it seems. https://schematics-free.com has a lot of free audio schematics... -
Schematics for the main board needed please. Sticker on board states BN94-07517A but the silkscreen says BN41-02157B. Cant find here or anywhere on the web.
Backlights work when main boards disconnected. When connected and power button switched, the relay on the PSU board turns on for one second then back off.
While relay is on, all voltage rails are present and steady (scoped) on main board.
I love a good logic puzzle but getting lost without any schematics.
No shorts on ANY capacitor main board.
