    DAC-12M030 rescue

    Hello everybody,

    First, i'm french so i'm very sorry for my bad english. Don't hesitate to correct me

    So, i need your help to rescue my computer display. I think there is a problem on the power supply board : DAC12M030. (A190E2).

    There is a little sound when the display is switched off. But when i switch on the ON/OFF button. The sound become louder and louder during five seconds, the display shows some white lines (CCFL lamps lights i think) during 0,5 seconds and the display become black.

    When i did the same test with a PC connected to the display, i could see my desktop during these 0,5 seconds.

    I have read some threads on this problem on your board like that :

    https://www.badcaps.net/forum/showth...t=29620&page=3

    I have tested the four AOP605 and i think it is OK, i never measure less than 6MOhms.
    When i disconnect the fuse F200. There is nothing when i switch on.


    My board seems like visually OK.

    I will post some photos.

    Thank's you for your help

      Lenovo Legion 5 high fan spin turns off after 34 seconds
      by twonk9098
      Hi all,

      I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
      I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.

      I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.

      I have tried a few new bios but exactly...

      Lenovo 15iml05 Power led lights for 12 seconds then off 12 seconds
      by liquidzorch
      Hello. I bought a faulty Lenovo ideapad 3, but it turns out the 3Valw buck converter burnt a hole through the board. I was able to clean it up, and remove all the shorts. I now can power the 3.3v rails from a bench power suppy while connecting the laptop to its psu, and I get the additional 5valw, 1.8v, and 1.05v, form what I can tell in the schematics, those are the only 4 voltages I should see before turning on, and they are present. When I hit the power button, the power indicator on the left side turns on (not the one on the power button), stays on for about 12 seconds, then turns off for...

      LG 23MP55HQ LED Monitor turns off after a few seconds or flickers.
      by Rick_1234
      Good evening, gentlemen.

      I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

      To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

      Harman/Kardon AVR 645 returning to stand-by after a few seconds.
      by PowellSkier
      A Harman/Kardon AVR 645 repair has been a hobby of mine for the past several years. My latest attempt involved the purchase of a DOA unit for part swapping and testing. The original AVR would power up then shut down after a few seconds. I completely tore down both units, found a couple of bad components and reassembled one of them. Same issue, no speakers connected. After extensive research I found a repair document from Harman/Kardon that explains the protection circuit in fantastic detail and provides specific test points for each fault (power, DC detection, overload & power) and the voltage...

      Macbook A1466 820-00165 resets every 10 seconds
      by AlexVG
      Hi,
      It have had a problem with U7100 and short circuit in Q7130.
      I replaced them.


      It starts now and waiting 20 seconds and then starts to reset PM_SLP_S4_L every 10 seconds.
      Almost all voltages rising
      except U3090 and U3210 (LED) - not receives enable signal.

      U4500 is trying to rise - receives enable only 2-3 seconds

      Here is my measuring of important signals.

      What else could be the problem?



      I need to help.
      Thank you an advance....
