          Try touching up the solder on the components that changed sound when you touched them.

                      I assume that in the full part code is NCP1203D60R2G,the '60' being the internal 60Khz ???? I have a DAP8( no letter A after it) would it be logical to assume that it could be the 100KHZ version NCP1203D100R2G.
                      I am trying to repair a Power Supply from a Viewsonic VX800. I have replaced the DAP8 with a NCP 60Khz version, and although that has the Supply now working, the PSU Output pulses constantly when any load is placed on it,and I am thinking the problem is because of the frequency difference between the DAP8 and the 8A ???

                        If it helps the DAP8A is made by ON semiconductor, and there sub package part number is DAP008D
                        The full number is DAP008DR2G
                        http://www.datasheetdir.com/DAP008DR2G+SMPS-Controller
                        I haven't been able to find a data sheet

                          Dead Acer AL 1916W Monitor
                          by noah95
                          Hello everyone, i have an old acer monitor "AL 1916W"


                          it was totally dead but after i replace some bad caps now the led turns green and red when it's in sleep mode.

                          but the picture at all no backlight or a dim picture in the LCD.


                          i just wanted to know how can i test the backlight and the lcd or from where to measure the voltage going to the backlight or the lcd, to know if the problem in the psu or not.


                          i did test most of the component there if there's a short but they seems fine.

                          ...

                          How to force Acer Aspire Series to bootup BIOS/UEFI on external Monitor?
                          by maralexbar
                          I ask this question in general as there are many Acer Aspire models with UEFI Insyde BIOS that do not boot to the BIOS on an external monitor (VGA, HDMI, etc) showing only the Internal LCD (LVDS, eDP etc).
                          It's a pain to work on Acer notebooks with a broken screen and not being able to access the BIOS using an external monitor.

                          If anyone knows how to force the external monitor as primary for Notebooks of those models
