    Vertical lines on Dell 2408WFP

    I used to have 3 vertical lines on the right side of the monitor when it was first powered on, but these would go away after 10 minutes or so. Now, I've started to get vertical lines throughout the full length of the monitor. It's no longer in warranty, so I can't get a replacement for it.

    Any ideas on where I should start looking for a possible cause?

    On that model the T-Con board is known to go bad. That'd be my main suspect.

      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.

      Screen Display Vertical Multicolor Lines
      by Stanley1843
      Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

      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...
