    Limited Label Beluga32/0 LCD tries to start

    Good evening folks,
    A friend of mine were very keen to get his 32" LCD up and running so of course I'm there to help.
    It's a "Limited Label model Beluga32/0" which tries to start up. It starts up the backlight for a second, then powersupply shuts off.
    If unplugging the backlight supply (+24V) connector from SMPS, the SMPS stays on.
    During that second the backlight is on, the picture appears to be normal.
    If the inverter were bad I assume the backlight won't turn on at all.
    So, probably the SMPS is weak and shuts off when the inverter needs the startup energy.
    BUT - I replaced the caps on the +24V line, with no help, so please look on the attached pictures if you may recognize something.

    Heh, it's a Vestel. I've seen this chassis and its variants far too many times.

    Replace the two 15nF capacitors near the main transformer and re-touch the soldering on all of the power devices and it should work.

    Or replace the PSU, it's only about £20 on eBay.

    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
    For service manual, schematic, boardview (board view), datasheet, cad - use our search.

      Thanks Tom! Will check this first thing. BTW - Great collection of servicemanuals in your database!

        Vizio E55-E1 bad backlights or bad inverter?
        by x_orange90_x
        I just got this tv today and it appeared to have no backlight on. After taking off the rear cover and checking again in the dark I can see that MAYBE one quadrant is lit.. But still it's quite dim. I was going to check the LEDs with my tester, and I found LED 1 and LED 2 + pins on the wire from the inverter, but I couldn't identify a ground. Nonetheless I tried using a mounting screw on the inverter board and also the chassis as ground but regardless my tester reads 300 which is what it reads when there is no voltage draw.

        I don't know how exactly to test the inverter itself. Is it...

        Onkyo DX-V500 Laser Disc Player - weird SMPS fault
        by dkneyle
        This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.

        Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS...

        APSINT3636VR 3600W APS INT Series 36V DC 230V AC Inverter/Charger schematic
        by Gentian
        I have a tripp-lite aspint 3636vr inverter charger which blow some of mosfet transistors. I replaced them repaired also the driver circuit and tested but the mosfets burn again.

        It work very well as inverter and also as charger if I let the rear switch in auto mode (inverter) and charger only(charging) but in auto when I connect the feed line 220V AC first time it pass ok to line and start charging the batteries but when I remove the feed line it pass to inverter mode and if I do it again the second time when passing from charging to inverter the Main transformer start making a...

        Insignia NS-LCD19-09 (PS OK, Inverter problem?)
        by valvashon
        For some reason I'm just not going to let this 19" TV defeat me. I guess because I have a schematic to work from I feel like I'm oh so close.

        History- while adding a turn-on circuit I let a small screw roll under the power board. Worked through all of that circuitry, probably replacing a MOSFET and PWM controller that were not bad but I was following the service manual. Finally figured out that the power supply is in working order when the inverter section (for the backlights) is disconnected. When the +12 supply to the inverter is disconnected the +12 and +5 will come up...

        HP Omen shuts down when loading OS
        by huzo
        The model is 15ec-1061nm
        Board number is DAG3EDMB8D0​

        SO i turn the laptop on , and as soon as it starts booting from disk, from usb, windows,linux,HBCD,anything i boot it just turns off....while in bios menu or in linux boot menu it stays on normally...It's like when it starts to use graphics it shuts down...But i measured 0.72V while working on the GPU power line,no excess heat is comming from GPU or CPU, i even removed the heatsink and turned the laptop on and everything worked fine, got a bit hot, fan span to full speed, but it worked like that for few minutes in bios...
