    Take it apart and look for potentially bad capacitors.

    Post pictures here. See misc #1 to see how to post pictures at

    If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

    Please do not post inline and offsite as they slow down the loading of pages.

      I agree with retiredcaps - I just rebuilt the power supply on mine and replaced the inverter board, although the problem was a little different, I had sound but no picture. There were MANY bad caps on the power supply, so I replaced tham all (about $30.00).

      The thread is HERE...

        Dell Optiplex 5050 SFF - strange behavior and service_mode jumper not working anymore
        by MMH3
        Hello,

        i have many 5050sff. all of them, and how i experienced over many years for all about 250 DELLs goin through my hands, are fully flashable and can be serviced in any way when the service_mode jumper is set.
        Never ever i experienced problems with that.

        Now i have one 5050sff machine, where this jumper isnt working at all.
        I do not get the normal messge that the jumper is set when booting and a short test with FPT just confirms this. Everything is locked -->> EVEN for reading !?

        The history of the machine is that i used it in my office...

        Asus x512dk rev 2.1 power on problem
        by Duranitron
        When I reflash again the bios of hoaca388 the unit powers on and the unit lives!!! Hooray!! All voltage in the coil 3.3v, 5v and 6.7v indicate charging are all present. including the cpu voltage , EEPROM and GPU voltage the unit is now alive, normal screen booting to windows and log in screen until I power it off. Then the unit never goes on even when pressing the power button in the keyboard.. Voltage reading 19v main , 3.3v VCC in IT8225E-128 and EEPROM VCC 0 volt and the charging voltage 0 volt.

        Try to trace the power switch button goin to the power switch IC PU8803 (APL3533AQBI-TRG)...

        HP ProDesk 400 G6 mini - BIOS Password attempt to remove it
        by beBoss
        Hi,

        as noobie to this please excuse my lack of experience.

        I am trying to remove a BIOS password from this machine:
        HP ProDesk 400 G6 Mini

        but so far I still have no success.
        I bought CH341 programmer and decided to give it a try.

        The programmer came with 8 pin cables and connectors or whatever everything else is called so I had to buy a new 16 pin cable because the chip which I think is the BIOS is with 16 pins..



        I connected everything and downloaded AsProgrammer and NeoProgrammer then installed drivers...

        Alienware m15 R5 Ryzen No Power
        by Green Probe
        Hello, I have an Alienware m15 R5 Ryzen, P109f002, with motherboard GDL56 LA-K453P Rev:1.0, Ryzen 9 5900HX, RTX 3070. I got it due to it having liquid damage. I am quite new to chip-level repair, and this is my second post, so please be kind with my incompetence. The charging IC is an ISL95522ah in HPB mode as far as I'm aware. I've been using a schematic for a LA-K455PR10_0525A that is available in the forum, and it seems to match for the most part. If it's okay I can link the schematic, or insert the pertinent page into my post.

        It had some crusty areas that I've cleaned up....

        Measures :
        PPBUS_G3H 13V
        PPDCIN_G3H 20V
        PP5V_S5 3 to 5V not stabil
        PP3V3_S5 1 to 3V not stabil
        PP3V3_G3H 3,40V

        After I removed I removed Charger and Battery, and measured the resistance to ground.

        PP5V_S5 1,500M

        PP3V3_S5 0,040M ( not stabil, goin up slowly)

        voltage to ground without connected Battery
        P3V3S5_EN 3.3V
        P5VXX_EN 0.00V
