    Schematic for qnap TS-453B

    Hi,

    Anybody can help with a schematic for a NAS ? Namely QNAP TS-453B
    On the board the only markings I can see are on one side
    HannStar K MV-4
    94V-0 E98382
    1647

    On the other side
    QY47 Rev:1.3 11611041346

    On the Box
    Model Ts-453B
    P/N 52100-002554-RS


    Main issue is it's only doing a blinking red led... No other sounds or anything.
    I'm curious if I'd get something on a serial console.. if it has any available.

    Thanks in advance!

      the good news is it runs Linux,
      https://www.qnap.com/en/product/ts-453b

      so they should really be providing the software and sourcecode under the GPL License.
      being intel cpu, it may run a console over a usb-serial bridge if you have a serial adapter to plug into it.
      or it could use one of the ethernets - can you sniff them with something like NMAP?

          I doubt it gets to any of the linux part.
          I thought about the console but I don't know any pins on the motherboard that would provide it.

                  Hi, This sounds similar to an issue I had with a nit a while ago. Did you check the LPC Clock signal ? Discussions and temporary fixes can be found here if you haven't and need to know how. A lot of units were shipped with faulty CPU's and exhibit this issue after a period of time.

                  Anyway, just a thought, hope it helps.

                      I see this is from a long time ago but I'll respond anyway. My TS-453 Pro had a jack inside that I could connect a 3.3 V TTL / USB like Adafruit Industries LLC 954. From there, I was able to monitor the boot process. the plug happened to be compatible with one of those sound card/USB cab.

                          QNAP TS-469L NAS schematic request
                          by spleenharvester
                          Long shot but does anyone have the schematic for this NAS, it looks like the board is a KN-20006-A01251-YS-RS? I have one coming in soon that turns on then straight back off again. Or at least a similar one (it looks like the TS-569L and TS-869L are based on the same Atom D2700 platform, and the TS-259 Pro II was based on a similar Atom D525 platform)

                          Cheers

                          Schematic vs. Reality: Where Are the Resistors on My Sharp Clock Radio? Model FY-70CH
                          by TinkerTron
                          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:
                          The schematic...

                          by atunguyd
                          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...
