    Re: Recapping Asus Board with Cool Stack

    The very first solder iron I ever used was heated by sticking it in the fire in the stove.

    It was my grand father's.

      No, I'm not using chipquick. Your problem is your flux is weak. I use plumbing flux with my 25 or 35 watt irons and I have no problems. I can even desolder large coils from multi-layered boards. The 35-watt I found in the trash. If this hobby makes me a million dollars someday, I might consider investing in one of those overpriced irons, but until then, I refuse to pay.
      I don't have the courage to try zinc chloride acid flux on circuit boards, and while I've seen rosin flux help make copper desoldering braid work better, it otherwise hasn't improved my luck with circuit boards. I do remember needing more than 25W to remove a 1.5-2.0" cube transformer form a single-layer board, and I don't think the problem was poor conduction between the tip and solder. I've never paid more than $5 for an iron, not even for my adjustable 10-60W, except for an $11 Radio Shack desoldering iron.

        How well did it work on surface mount chips?

        How about for branding cattle?

          Zinc Chloride flux is quite nice to work with, but it needs a bit higher temperatures to function properly and it is also quite wet and spews everywhere.
          It removes oxides nicely, tho it doesn't improve wettability much. Ordinary flux is much better for this purpose.
          It however does _magic_ on old copper wires (and is corrosive as hell if you hadn't cleaned it properly)

          Fumes of such flux are also quite aggressive on your lungs and with no ventilation I would not recommend it.

          Plumbing flux is something I would avoid as they are mostly acid based.

          I dip my braid in colophony and 'tin' it a bit, works much better then, despite being a bit contraproductive, but you can't heat the pad with dry braid, does not work.

            I dunno. I was about 10 or 11.
            Worked pretty good for soldering tin cans together.

              Just recapped a Asus P5AD2-E Premium with no success. Board LED lights, fans come up, but no beep, no post, no monitor. Wondering if the process of resoldering Stack Cool could have anything to do with it? When I replaced the caps, I soldered the caps to the Stack Cool, assuming/hoping the solder somehow drops onto the contact on the primary motherboard. Is that how it works? Does the Stack Cool have any electrical contact with the primary motherboard?

                a 25w iron will only do the job if it has enough thermal mass.

                  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.

                  Assuming...

                  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).
                  ...

                  by howardc64
                  All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                  • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                  • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                  ASUS ROG STRIX B550-F GAMING — Board not powering on properly
                  by ShadowAi12
                  Hi,
                  I recently bought an ASUS ROG STRIX B550-F GAMING motherboard that was listed as "dead, not powering on." However, it does show some signs of life. I've performed several basic measurements and would like to share the results.
                  • The board enters a "ready to power on" state after plugging in the PSU.
                  • Pressing the power button increases power draw.
                  • Sometimes, touching the RSMRST_L pad with a multimeter probe causes the board to shut off and return to standby.
                  Measurements:
                  (taken after pressing the power button, while the board is attempting to start)

                  Faulty ASUS X99-PRO board. Some progress with repair. Need advice\help please.
                  by jimbodriver
                  Hi everyone,
                  I am trying to learn electronics repair. I purchased a “faulty for spares/repairs” ASUS X99-PRO/ USB 3.1 motherboard for a very low price from ebay – a good enough price to offset the high probability that the board was completely toast and not realistically repairable.
                  Initial results:
                  Board would power-cycle when turned on either with switch on board or shorting pwr pins. Fan would spin for a second or so and a QCODE of 00 would display then it would power off and then do the same thing again over and over. I think maybe 2 times in about 100 attempts...
