    ASUS TP500L No backlight

    I was replacing the glass LCD on a ASUS TP500 when the backlight went. I can still see a faint image by shining a flashlight on the screen and the HDMI works for mirroring the display. While looking at the mother board I found what's in the picture. Is this a fuse or resistor? I get fluctuating numbers when I measure it which is why I'm not sure.

    Also does anyone know where any other fuses are located on this board? Model number on the board says TP500LN Rev 2.0.

      Identification is printed on the board R Plus a number is a resistor

          That's what I was hoping to see, but (as in the picture) it isn't labeled. Or is it and I'm missing it? That is a resistor correct? So I can't just bridge it to test?I've also attached a shot of the opposite side of the mother board, the parts in question are directly below the video connector.

              Usually A SMD resistor has a number on top with a resistor calculator you can determine the ohms rating
              I use resistor calculator app on my phone.

                  So can I assume its a fuse then? When I measure it I don't get an open like a traditional failed fuse, but the meter also jumps around and never settles on a small range ( I don't have a small set of probes either, just standard size).

                      That's an smd capacitor, just remove it, use sodding iron with LED to cover the surface and you're good to go.

                          Just any SMD LED to bridge the connection? Can I just bridge it with solder?

                              Actually are you referring to the black component with a hole in it or the brown one?

                                  by Tynan Dill
                                  I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                                  Upon bringing it home and plugging it up, it showed a standby light.

                                  I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                                  The screen seems to blackout and stay black, but with a flashlight I can see the display.

                                  With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                                  Assuming...

                                  Backlight problem - Asus M3200WU, board Gapal LA-L291p
                                  by Honziq
                                  Hello,

                                  I have this All-in-one PC, after SSD change there is no picture. I was found out it is a backlight problem, but LEDs are OK. There is 4 led strings each working on 42,4V, but from board is comming only 5V.

                                  I was repaired many backlights before but this design i will not understand.

                                  For me it looks like it is waiting for some signal from screen to start up the backlight or something like this. Nothing seems to be damaged or shorted here.

                                  Can someone explain me please what to do, what to check?

                                  Thanks....

                                  ASUS STRIX Z490-F GAMING - No POST, stubborn board
                                  by DynaxSC
                                  Hi,

                                  I have this very stubborn ASUS mobo on the bench, and I already face the wall with it. It just refuses to POST, although everything seems to be OK.

                                  The situation looks like this:

                                  After connecting the board to the power supply on Nuvoton (SLP_S3#, pin 64), the Low signal (50 ohm resistance) appears immediately. PWRNTN# signal goes through Nuvoton to the chipset (confirmed after removing the chipset). The following conditions are then met for the chipset to generate the SLP_S3# signal:

                                  1. RTC oscillates normally (32.768KHz).
                                  ...
