        Re: SIO remove pads on the board

        you can connect it,i see only one missing pad,it is 6th pin from the end(pin nr.123).You must look in schematic,maybe is not conected and under the pin was only free pad. Other pins carefully straighten with some pike tool and solder it back..fine solder tip,good flux and microscope-10minutes of work

                I see some pins are connected together. Do not plug power/battery into the laptop to avoid damaging the SIO.

                  i dont have schematic for this board but this one pin can be also not connected-not in use..separate the pins and solder it back to the board..leave the one unconected,i dont see any trace going to this pin

                    some pins looks like bend (or bent ) . check with good magnifier if they are isolated or touch other pins before give power. if so, better put a new one and use a bit of extra solder 60-37 without extra flux on the missing pad.

                      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                      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.

                      Problem

                      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                      How do I remove the chip from the board
                      by gusto
                      I am new to hot air soldering. I need to remove one chip from the board. I have a hot air solder and I set the temperature to 350°C. I slowly started heating the chip, but the solder didn't melt. I heated it for about 5 minutes, but the solder still wouldn't melt. I increased the temperature to 450˚C and still nothing. After a while, the board started to change color, but the solder still didn't melt.
                      Fortunately, I'm testing it on old network switches to see how it works.
                      What am I doing wrong?
                      I've seen a lot of videos on youtube and everyone got the solder melted and the...

                      Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
                      by acedogblast
                      This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

                      There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...
