    dell 2407wfp black out

    Hello all

    My first thread!

    I have a dell 2407wfp. I have tested it on multiple computers with different graphics cards. It's definitely the monitor itself not the GPU or driver.

    I'm thinking it's a heat issue. I did modify the outer plastic cover a little to give it more ventilation to no avail.

    When 'cold' the monitor will run for about an hour depending on the ambient temperature (the warmer the shorter teh duration)

    Once it blacks out, no buttons respond, but all stays green not like sleep mode which is orange. Unplug power, plug back in and it starts up ALWAYS displaying the DELL startup logo and then will black out again quickly and increasingly quickly untill it just stays black, but always displaying the DELL logo. Here's a video.

    Where to start with the trusty multimeter? Any ideas?

    cheers,

      Id start with a trusty hairdrier - gently heat sections of the boards at a time until hopefully you narrow down the spot where heat causes it to shut down. If you are lucky it wont be the main processor.

          Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
          by HTR-Informatique
          Hello,

          YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

          I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

          On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

          I also changed the screen because the PC fell and the screen was broken.

          I changed the battery with a new and original battery.

          I also had corrosion/oxidation on the...

          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

          Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
          by Bowline
          My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

          Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

          My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
          The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
          I have tried multiple different Dell power adapters. My Dell...

          good morning all,

          i purchased a used dell e6540 laptop used 10 months ago from a vendor on ebay. intel i-7 processor, 16 gb ddr3 memory, 256 gb ssd., mobo la-9413p (rev 1.0 dated 2014-08-04). i've inflicted no damage on it since purchase but its past is unknown. starting 2 weeks ago it began to fail to boot (initially 9 of 10 boot attempts failed, now 10 of 10 fail). there was no new hardware or software added (i was using as a kodi video server). the post process doesn't complete and booting no longer displays the dell logo screen - screen remains black with no backlight. some other...

          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...
