    17ips20

    Will get pictures etc later on

    No backlight

    LED Driver only ever goes to 80v and stays at 80v

    Having a hard time figuring which connection is BL_ON

          Cheers but not really

          Never dealt with LED drivers etc....

          Going to need some guidance....

          I have a schematic for it.... I have tested what i think is BL_ON and reads 0v.... Though cannot be 100% sure it is BL_ON I am testing

              To what I know the driver voltage should be at 115v then boost to 180v right?

              Any way of forcing BL_ON?

                  The way to force BL_ON is to disconnect the plug going to the main board and using a 500Ω-1k resistor connect it between standby and BL_ON, you will likely also need a resistor between standby and PS_ON because the main board is disconnected
                  If you don't disconnect the main board you risk damaging it
                  The voltage to the backlights depends on the panel and how many leds and there configuration

                      Help figuring out the resistance of this exploded resistor. gtx 1060 6gb inno3d compact
                      by Bivolalbert


                      Hello,I need help figuring out the resistance of this exploded resistor. I'm pretty sure it's the one labeled R37. I tried measuring it with a multimeter, but I got different values each time, probably because it's exploded. If you have a schematic, it would be really helpful!
                      Its a gtx 1060 6gb inno3d compact, i you have schematic it would be very helpful....

                      Sony PS4 ADP400DR - help needed figuring out shorted pads under capacitor C 31
                      by supravit2000
                      Hi!

                      A friend of mine gave me a dead PS5 to look at. I am totally inexperienced, but when a damage is simple (i.e. failed DAP41 on PS4s, etc.), when replacing just the IC and the other very common failing parts of these consoles, problem is fixed. So I checked the voltage of the PSU - none was present. Model is ADP 400DR. I have a bunch of spare parts around, so first thing I did was to replace the IC DAP 053 (they seem quite expensive, so I put a replacement unit - TEA2016AAT. When plugged to the power outlet, 12V did come present.
                      So I reassembled the PS5 and pressed the power...

                      Need help with figuring out a capacitor on Quadro 5000M from Dell M6500
                      by remdale
                      I have a rear video card Nvidia Quadro 5000M, but I broke a small SMD 0402 capacitor on the front side of the card. It's the 2nd capacitor just down the U1 inscription in the left bottom corner of the card. Would anyone having this card please help me measure the capacitance of it? It would require a bit of soldering.
                      To those interested in this card: I'm working on replicating it, so you might become interested in buying it from me after I finish. I'm also planning on changing its shape to fit some other laptops.

                      by psdavid65
                      Quick Question Please.
                      Is low resistance on gate pin 5 of U202 normal? I have a very very low resistance of 5 ohm on this gate. In diode mode, it looks shorted and beeps. Is this a normal behavior of this FAN6300 IC?
                      All other components on this vestel board have valid readings except for this U202 IC.

                      Bad Vestel 17IPS20 : shortage, need help
                      by worlor
                      Hello,
                      My Vestel television has stopped working.
                      After first diagnosys, the power board 17IPS20 R6 don't work (no 12V on output).
                      I have replaced :
                      • U300 FAN6300 -> completely blown up
                      • Q301 MOSFET FQPF8N60C
                      • C387 1uF Capacitor -> shorted
                      • C295 & C296 1uF capacitor -> to be sure


                      But with my multimeter, there is conductivity between VCC and GND on U300 and U202. I don't know why. Maybe a diode but i can't test these because of the short.
                      Can you help me to find the cause of the shortage ? have you any ideas ?

                      I attach...
