    Dell 1707 2 seconds to black CCFL testing

    I have a dell 1707 with the 2 seconds to black problem. Having already replaced the power supply board, I thought I would test the CCFL tubes next. I was looking on ebay for FFCL testers and found some with different output ratings.

    1300 volts with type 7 mA
    950 volts with type 6 mA
    670 volts with 5 mA

    Does anyone know the rating on those CCFL tubes on the dell 17 inch monitors? Is it the same for the dell 14 inch and 15 inch? So far I have not taken apart the CCFL tubes so for me the "fun" is just beginning.

    You can build one pair or two pair of test lamps to verify the boards first before spending money on tester.

      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...

      Dell Inspiron 5593 shutdown after 5 seconds
      by DrFalken
      Hello everyone!
      Motherboard model: FDI55 LA-J081P
      Today a customer delivered this laptop completely dead, with the original power supply shorting when plugged into the connector.
      I found and replaced a shorted MOSFET (PQZ3).
      Now the laptop turns on (fan runs fine but no video signal) and after 5 seconds it turns off.
      BIOS has already been updated (both 64MB and 128MB IC)

      +3VALW and +5VALW are still present.
      +VCCIN = 1.8V stable (measured on PLZ1 at power up)

      Abnormal readings:
      PLZ1 to GND = 0 Ohm
      PLZ2 to GND = 0 Ohm
      ...

      HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
      by ttmi100x
      Greetings everyone,


      I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


      The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
      Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

      Upon closer inspection...

      Dell Inspiron 3542 Turns on works for 30 seconds to 1 minute then turns off
      by Kambi13
      Hi all need some help, I've got a Dell insprion 15 3542 that turns on works for about 30 seconds or sometimes a minute or two and then turns off and wont turn on again until I remove and replug the power connector
      Not heat related, everything is ok regarding to that.
      All voltages are present.
      Wondering if this as anything to do with one wire circuit, the charger is not original, but it was working fine

      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...
