    Hyundai L90D - No OSD

    I've searched the forums using "L90" as my search string and found only one entry not related to my problem, so if this has been covered, I apologize in advance.

    My monitor was working fine until I moved. I used the original box the monitor came in for the move.

    Symptoms:
    Unit powers on and stays on, backlight does come on, "Menu" does not show, and no video appears from known good source. Tapping the back of the unit smartly causes a "white flash" on the screen. Disconnecting the SVGA cable yields a blue screen after a minute or so. I do not own a DVI cable to test that input. While connected, the unit does sense a video presence as the LED stays green until I shut down the PC, then it changes to amber.

    It's been 12+ years since I've repaired consumer electronics, and LCD screens were a dream to own at the time.

    Any ideas on where to begin troubleshooting on this one?

    Many thanks,
    TXShooter

    I would take it apart, clean and reseat all the connectors. If that doesn't work, then post clear focused top down view of all your boards following my sig file below EXACTLY.
    --- begin sig file ---

    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.

    We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

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

        Repair of an LG split AC system indoor unit PCB
        by ngml
        I am trying to repair an LG split AC indoor unit, which does not start and gives a CH05 error code.
        This indicates an error in the communication between the outdoor and the indoor unit.
        The outdoor unit is fine, so the problem is the indoor PCB.
        The indoor unit is an LG PC09SQ NSJ (3SNM09JA2FA), and the PCB has the following type number: EAX35907219-1.2 (see photo1)
        I changed optocouplers ICO1X & ICO2X and the NPN transistor S9013 which drives optocoupler ICO2X (see photo2), but this did not remedy the fault.

        Does anybody have the schematics of this board,...

        Bose Companion 5 - Unit Powers On then Cuts Off Shortly After
        by nobbnobb1
        Hi guys,

        Trying to salvage a Bose Companion 5 computer speaker system that powers off shortly after powering on. It's got a primary USB input (built in DAC) and an aux 3.5mm input. The USB appears to be the primarily source that tells the unit to power on (control pod LED goes green) as the unit has no power switch.

        When I first connect power to the unit, plug in the USB, it will play audio nicely for a minute before it drops out and the unit appears to go into standby (control pod LED goes red). It stays in standby and I cannot seem to power it back on without physically...

        Air-conditioning unit power supply failing to power up
        by Gjackson
        Hi all, I managed to narrow down which PCB was causing my Haier AC to throw out an E7 error code (E7 indicates that the indoor unit and outdoor unit cannot communicate). I found that the outdoor unit power board which gives 5v and 15v to the outdoor unit module board fails to fully power up.. The power Led starts to fade in incredibly slowly and the 5v and 15v power buses jump around like crazy and never reach their required voltage. I unplugged the module board from the power board and the power board powered up fine! It had a steady 5v and 15v out and the power LED came on instantly and Bright....

        Hitachi Power Supply Unit Interchangeability
        by navagator
        I have a Hitachi 57F710E rear projection set with a bad power supply board. I've tried to fix it with help from this forum as well as another one, but without success. Today I found a Hitachi rear projection set for sale on Facebook that looked just like mine. After contacting the seller I found out it was a 51F510. According to the service manuals my set uses a HA01312, POWER UNIT DP4X-DM_24W and the 51F510 uses a HA01313, U901, POWER UNIT DP4X_24W.

        Does anyone know if these 2 power supply boards are interchangeable?

        Thanks.

        Repair Success! Middle Atlantic UPS2200R-IP
        by valvashon
        Yesterday I successfully repaired a Middle Atlantic UPS2200R-IP that had inadvertently been used as a surge suppressor at our transmitter site. It has already been replaced with an updated one but it's coming home with me now instead of being e-cycled. To be specific, this is the MA model that has the blue backlit display and has been discontinued, although this design may have been used in many UPS units including the smaller Middle Atlantic ones in this series.



        Here's what happened: We experienced a brownout/surge at the site, which damaged the UPS and took our broadcasting...
