      Dell monitor PSU vs Dell laptop PSU
      by keepread
      Hi there!
      Someone gave me their old monitor, it's Dell S2715ht.
      The owner was using it when his PSU began to smell and then to smoke. It literally began to melt. He turned the monitor off, pulled the PSU, and ditched it because it was smelly even after it cooled. So I got the monitor but not the plug.
      Now, I tried to bring the monitor back to life, by plugging one of my many Dell laptop PSUs. They are of the same 19.5V, and the wattage of the laptop PSU is higher than that which the monitor is rated for. Visually, the socket on the monitor seems compatible, and the plug plugs...

      Seeking Advice: Repairing Dell U3425WE Monitor with Faulty USB-C/Thunderbolt Ports
      by Borse2008
      Hi everyone,

      Looking for some advice or opinions on what to do with a monitor issue I’ve run into. Apologies in advance is this crossovers a few forum categories.

      I have a Dell U3425WE, which I've recently replaced with another model. That said, the original unit is still fully functional in terms of the display — it works perfectly over HDMI and DisplayPort. However, the USB-C and Thunderbolt 4 ports have stopped functioning correctly. The Issue:
      • The 90W Thunderbolt 4 port (circled in the photo) no longer charges or powers any device, including laptops or MacBooks.
      • There’s

      Aorus 17G YD laptop, broken display, could not switch to external monitor
      by ArchangelGabriel
      Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop. Broken display, some cable ripped form daughter board connector, case broken, battery discharged and probably locked, etc. After I did the most tedious job I ever did on soldering back the broken cables (shielded cable) , I measured resistance on CPU and GPU core, 3 and 5 v ps and any coils I find on the board, everything seems to be fine. After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have

      Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
      by DanPoka
      I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
      Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
      This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...

      Dell Latitude E5550 - Strange Internal LCD (BIOS?) Issue
      by Eradicatus
      I have a problem with my Dell Latitude E5550 laptop, in particular with its display.
      This laptop has been sat under my desk (unused) for quite a while and I wanted to reinstall Windows and use it for some ad-hoc testing.
      However, I am struggling with the display, which is playing up.

      1) When the laptop is left switched off, after switching it back on the internal LCD does not work. No images are displayed at all - no DELL logo on POST, no messages, no Windows desktop. But I can hear that Windows starts up correctly, so no issues with the rest of the system - must be...
