    Re: Iiyama b2475hds died.

    an update for who can be interested in,

    I had similar On/Off problem, and as seen on polish forum, I ffixed the problem by:

    1. Resoldering of all 8 Pin Smd component on the mainboard.
    2. Resoldering of the main processor ( Novatek )
    3. Replacing of the 470uf 35V Capacitor on the power board.

    Good luck,

      Thanks for that update.
      I have te same problem.

      How did you proceed to resolder the main processor (Novatek) ?
      How are you equiped ? (not a basic soldering iron, I suppose...)

      Thanks in advance.

        Hi Satbel,

        thanks for the update.

        I still have this monitor stored away, but now determined to repair it. I installed a heatsink on the Novatek processor as described in the polish forum, but it didn't help much (still 2 x switched off in 2 days).

        I don't have good measuring equipment, so I will replace the two 680uF 10V Lelon capacitors + the 470uF 35V capacitor with low ESR ones.

        I was wondering how you did the reflow? There are so many DIY manuals out there (heat gun, oven, etc), and it's not clear to me what really works, and at what temperature I should try to reflow, how long, etc. I have an oven, and would have access to a heat gun. If you can write me your procedure, I could just follow it.


        thanks in advance

          Acer Nitro 5 AN515-54. displays on the external monitor and works fine, the issue is NO display on the internal screen
          by DqMagetz
          Good day!
          I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.

          Here are the voltage readings:
          • Input – 19V (stable)
          • +LCDVDD – 3.3V briefly, then drops to 0V
          • EDP_HPD – 3.3V briefly, then drops to 0V
          • PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
          • EC BKOFF# – 1.8V briefly, then drops to 0V
          • PANEL_OD_EN – 0.3V

          Is it possible that the EC chip is corrupted or damag...

          Need help replacing led strip on Iiyama Prolite XUB2390HS monitor
          by mikey5791
          Hi,
          Got this working ips led monitor by the brand of
          Iiyama Prolite XUB2390HS presumably a 23 inch type given to me with suspected bad led backlight. To test it, i unplugged the bad flat ribbon type connector and plugged it a good flat ribbon led connector scrapped from a HP Pavillion 27cw (led strip with 60 led). Good news is the HP led strip lights up but not fully, in between there are about 15 unlit leds.(as picture attached shows).

          Fyi, i had not opened and removed the old bad led strip. My question is whether is it possible to cut some of the extra leds(say...

          Macbook Pro A1989 - No image, working fine with external monitor
          by Madoy104
          Hi everyone,


          I have a MacBook Pro A1989 that was likely exposed to liquid. It doesn't display an image on the built-in screen, but the screen is backlit (you can't see the Apple logo or any other elements when held up to light). The laptop provides 20V and 1.5-2A, and it works fine when I use it with an external monitor. Currently, the connector for the display (J8500) is disconnected. I'm writing to ask for help in diagnosing the issue. I've heard that when the J8500 is exposed to liquid, the processor pin responsible for the display might short-circuit, and I'd like to know...

          Asus G15 5980HX - 6800M - No Display on Laptop - HDMI/Display Port external monitor works fine. Fried Component.
          by amuse619
          Hello!
          Looks like I fried something when my EDP cable got squeezed on the hinge. I replaced the cable but still no display. Laptop works fine with external monitor connected through HDMI and Display Port-USB C port. I took it apart and I see a burnt component. Can anyone help me identify what this component is? I tried to use schematics for another G15 but it does not match on the amount of pins and size. I attached pictures. The component has a label on it - (21A29)

          Laptop is a Asus G15 Advantage Edition 2021 Laptop Ryzen 9 5980HX - 6800M...

          AOC AG493UCX 49-inch monitor - Firmware request
          by wattage
          Hello Badcaps Community,

          I purchased a preowned AOC monitor that is not working and out of warranty. It was sold as not working. I am looking for guidance on self-repair. In particular, I am after the firmware for the monitor. At the end, I have included monitor model information and links to pics and vids of the issue.

          The problem is that it will not display a picture on any of its inputs. And the on-screen menu does not appear. The power button works properly. It powers on with the remote as well. But the on-screen menu does not appear, even when not connected to any...
