    Sanyo DP42647 Backlight issue

    I got this tv in today for repair. I have checked it using the flash light test and can see a faint image of the video with the lights off. I have ruled out the main power and main board. I have tested voltage to the inverter transformers on master and slave. I get 24v to the inverters on the master and nothing to the slave. It is the 2 second to black condition. Is the slave board bad or is there another problem I am over looking?

          MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
          by rounin
          Hi everyone,

          I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

          🛠 Original Issue
          The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
          Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

          I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

          Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
          by ugamazing
          I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

          We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

          HP 15-cw1002ua strange keyboard issue

          Hello guys!
          I have a strange issue with my laptop keyboard and I'm lost trying to detect what's wrong - the KB9028Q-C or the keyboard itself.
          It powers on OK and has no other issues except the following:
          • CAPS LOCK does not work at all
          • Fn button toggles Flight Mode
          • When I press 't' or '5', it produces 't5', and when I press 'y' or '6', it produces 'y6'
          • (with SHIFT pressed: 't%' and 'y^' respectively)
          I initially thought it was a keyboard malfunction (internal short, etc.),
          but when I press and hold...

          Alienware 15 R2 Service Tag: DL7NN32 ISSUE (Battery is not charging)
          by Simone Vergani
          Hello everyone,

          I'm experiencing an issue with my Alienware 15 R2 (Service Tag: DL7NN32). The laptop works perfectly when connected to the AC adapter — it powers on and functions normally. However, the battery does not charge. If I disconnect the DC adapter, the laptop shuts down immediately, as the battery is at 0%. I have replaced the battery with a new compatible one, but the issue persists. I also replaced the AC adapter with a compatible one, but the battery still doesn't charge.

          To assist with troubleshooting, I'm attaching two power circuit schematics:

          Hello everyone,

          I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

          I have checked the forum and the available documentation but could not find a solution specific to my issue.
