    start Problem with syncmaster b2330

    hello guys
    i have problem with syncmaster b2330
    i'm sorry i've no camera so i borrow the pictures from another thread https://www.badcaps.net/forum/showpo...09&postcount=1
    it looks like this one exactly
    in the past thread they were talking about PWM problem
    and measuring Vcc and Vst they're fine 14.6 V and 322v on pin6
    the pins out to data board is fine as printed voltages
    how can i diagnose this board correctly ,
    the monitor has no power or no blue light comes out from panel
    some times the light up and it work correctly but turning it off won't make it start again
    i've measured allot of components all fine please guys help and also used external lamps
    it's not alamp matter
    any ideas would be good

    Problem with LG Plasma 60PM6700 - Random power downs
    by theone111
    I have an LG Plasma TV 60PM6700 for the past ~12 years.

    In the last ~3-4 months I have been having some issues.
    1. Problem: It started with random picture disappearing (sound still worked).
      Frequency: Happened about once a week.
      Solution: Had to turn off TV wait a few seconds before turning it on again.
    2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
      Frequency: Happened about once a week.
      Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
    3. Problem: TV shuts down

    Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
    by Zeonalbasta
    i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
    The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...

    Samsung Syncmaster 943B problem
    by falcontech
    Hello
    I have a problem with a samsung 943B, initially thinking it was a power problem i replaced the power board which is a bn44-00082e, i had a flashing of the ccfl lamps and the monitor would not start, i replaced the power board and the problem is remained, thinking they were the lamps I tested them with a ccfl lamp tester and they are all working, at this point I think it is the main board which is a BN41-01172B, my question is, before making a further purchase there is a way to turn on the lamps without the main board to exclude that the new power board is also broken? Of course without...

    Lenovo T580 - LCD Panel problem - error 0288
    by perzyk23
    Good morning,
    I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....

    Samsung Syncmaster 740BF repair
    by soopacrucial
    Hi folks,

    I'm new here and was wondering whether you might be kind enough to give me some advice on troubleshooting the following problem:

    Quite a few years ago now, a couple of years from new, my Samsung Syncmaster 740BF LCD monitor starting playing up by making a buzzing noise and then the display would go blank. I seem to remember the blue power led would also go off when this happened but that I'm not 100% sure of. By pressing the power button I do remember I could at first get it working again but eventually the problem would come back. At the time I had read about...
