    What liquid to use

    I would like to repair faulty backlight in Philips TV. In various videos, guys use a liquid before using a suction tool.
    Can anyone let me know what kind of the liquid is it? Or what liquid do you use?
    Thank you
    Here is a video

    Most likely water or alcohol. He just does it to make sure there is good contact and suction. I don’t use suction pads as I’ve had 1 loose grip and drop. Never again

      It will be water, but that is a poor way to remove a screen, he's using the wrong tool for such a large panel.

      What size panel are you removing ?

      Don't ever use alcohol on an LCD It damages the coating.

        Yea I use two suctions in each side. Has 2 cups for each hand at a total of 4. I've also had one of the suctions lose grip, which thankfully the other held. Just use water. It's just to clean the dust off to get good suction.

        Like $7 each at harbor freight. Good tool

        Edit. I also watched him leave a pile of liquid while using the suction. Just make sure it's clean, you don't need no liquid there. Just clean where ever the suction is going to go

          Thank you for replies.
          At present I have 40" size screen. I have never removed such a large ( at least for me ) screen before. So, is it wise to use suction tools or is there a better way ?

              The 40 inch tvs aren't too bad, it's the bigger ones that are really hard to handle, video there, notice how he's careful with the driver boards attached, if you rip one of those it's pretty much game over, he doesn't use any suction cups. I Have used a piece of cardboard a little bigger than the screen and gently lifted one side and slid it under the screen before removal so it is supported. Take it slow, you can do it: https://www.youtube.com/watch?v=thfDx2xWoM0

                I'd still use suctions. Many of the Roku brands glue the screen down or use double sided tape. The suction allows you to apply small pressure up while sliding a card underneath to release glue/tape. I use paper business cards. Without the suction you just have the sliding force with no leverage pulling up. But yes for a small screen it's much easier to do. But since I have them I never not use them.

                  Just lightly wet the suction pad with water it ensures a strong grip
                  and avoids slipage.

                      Isopropyl alcohol as a cleaning agent?
                      by ClockChip
                      Hello All,

                      I wanted to check with the board before I do anything foolish and/or irreversible. Can someone please set me straight on the use of isopropyl alcohol to clean electronics? I understand it is commonly used to clean electrical contacts. However, in this case, I am wondering if I can safely immerse a small electronic item in alcohol provided a) all power has been removed and b) I take care to dry it thoroughly before re-applying power.

                      The short version is that I am seeking to clean an older used (well-used) electronic item. The basic plan is to immerse it in...

                      Strange liquid on damaged GTX1080 card
                      by kurland
                      Hi,

                      I'm fixing a GPU card for a streamer, was sent to me by mail. A shorted cap on a power rail has severely burned the PCB.



                      As you can see from the darkened PCB around the mosfets there are signs of liquid damage. But it's odd because the person says no water has entered the PC cabinet. If you spill something on a desktop you would know I guess...

                      Funny thing is that the liquid is not only on the PCB but on top of many chips which are tightly covered by thermal padding under the heatsink, even on top of some of the RAM chips

                      ...

                      Liquid cooling?
                      by Hondaman
                      I hope my computer does not randomly reboot while typing this. My main system is the AsRock 970A-G/3.1 motherboard with the AMD 8150 chip. I am experiencing FREQUENT and RANDOM reboots once the system is used for a couple of hours (sometimes it reboots before I even get to the Win7/Linux Mint dual-boot screen). The problem MIGHT be the DRAM controller chip (I recently upgraded to the maximum 64 GB RAM). It also might be the VRM chips. I am using a typical aftermarket CPU cooler, which does NOT blow air DOWN onto the VRM heat sink.

                      (After previous generation hardware [Gigabyte] didn't...
