      Are these pictures before the capacitors were replaced?

              General questions:
              What brand and series of replacement capacitors were used?
              Are they all in the right way, polarity-wise?
              Are you sure all the cables are reconnected correctly?
              What happens when the power button is pressed?

                  Wait--isn't this just a duplicate of this thread?

                      Right you are. Now I can ignore both of them.

                              Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
                              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 downloaded firmware from sony and there is no .pkg fike.. after extracting it gives another file which contains multiple files like inf, payload.bin and 3, 4 other files. i just did that usb but did not worked. anyone knows anything how to do it..?

                              green amber blinking stops after while and then starts again. tv responds to remote control on off etc. before installing new tcon backlite was coming on without backlite...

                              GDM50 LA-L241P Rev 1.0 - 2 Amber and 7 White Led Fix Needed
                              by m041633n
                              Hello Everyone!
                              I would like to know the Jumper location for the 2 Amber 7 White Led Blink Code error. According to Dell 2,7 Led codes are for display or the Display cable failure. I didn't changed the display nor the cable. The issue happens only when restarting the machine from windows and from the BIOS. And when opening and closing the lid the display turns off and never turns back on. But the machine is working! I confirmed it by pressing the CAPS Lock key. Does anybody has this issue and fixed it by jumpering some fet near the display connector on the motherboard. If So Please Help...
