    Benq G2010WP Powers off

    Monitor powers off for some seconds and come back for some seconds… do you think it's the power inverter or a controlling unit.

    There I got a picture of the power inverter board.

    Best regards

      Without more detail, you might be experiencing 2 seconds to black which is documented in posts #19, 20, and 21 at

          can i also try this if my power LED wents off?
          I mean the monitor loses the whole power.

              Check the power supply lines to the signal card, in particular the 5 volt line. If it's stable, the problem is probably on the signal card. If it's changing, look at the power supply or the inverter.

                  Signal card is the card where the display connectors are placed on?

                  I also watched for the inverter because i read that in other forum posts. My problem is that i dont know the inverter on the postet board.

                      Correct, the signal card is where the signal connectors are. The inverter is on the power supply, and if it is bad, it could be overloading the power supply. That would cause a drop in the 5V supply. So as a quick test, we check the 5V supply

                          Hey Bill,

                          i checked the supply line and its constantly 5V ... i also checked the brightness line and it is 4V ... does that mean something?

                          what next? could it be the signal card then? How can i fix it now?

                          Best Regards

                              The voltage on the brightness line is unusually high, that could be the result of a problem on the signal card. The next step would be to check the output voltages of the regulators on the signal card.

                                  Hey Bill,

                                  Thank you for your help. After i checked the voltages, i rebuild the monitor and tried it again. Its running since 2 hours without any failure.
                                  Should I still test the voltages of the regulator? Can the unusually high voltage of brightness damage the monitor?

                                      You either have a bad connection, or more likely, a bad solder joint. As for the voltage, Benq may have used a different design to generate the voltage.

                                          by lostone
                                          Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

                                          First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
                                          When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

                                          I have an Alienware 17 R3 (board is a C912P) that I recently starting trying to repair. Originally the issue was the charger going into protection mode when plugged in to the laptop. I found a short on the motherboard (one of the capacitors on the back of the board under the DRMOSes for the CPU) and the charger when plugged in now doesn't go into protection mode anymore. The laptop powers on, the lights on the keyboard, alien head, and alienware logo light up, and the fans spin. The issues are:

                                          1) The battery doesn't charge. I've probed the charger jack and it's only receiving 0.633v...

                                          This laptop come in with liquid damage. I located a couple areas on the board which honestly didn't look bad at all. I ISA them and cleaned up - can't even tell anything happened. However, when I power up the computer, it will shut off after about 10 seconds. I discovered it seemed like the fans weren't coming on because the board was getting mad hot right around the battery charging mosfets and coil. Anyhow, I checked under the thermal camera with just the power adapter connected but the machine off. I have marked what is warm at that time. Once I power it up, the coils near CPU vcore start heating...

                                          by survivalbloke
                                          I've got a Dell Latitude 5580 which came in for no power. It's not exactly a no power issue though. The battery was puffy so I replaced that, but the symptom is that when the power button is depressed, the keyboard backlights will come on for about 10 seconds then go back off. Before depressing power button, I am drawing 112ma and oddly, there is no change in current draw once the button is pressed and the keyboard backlights illuminate.

                                          Any ideas?

                                          The capacitor on the board was slightly bulged at the top so I replaced. Unfortunately the cap I bought on eBay was much thinner than the original, even though the spec was the same (4.7uf 100v). The problem persists. Would the thickness of the cap actually make a difference - is it worth trying to find the correct one?
