What liquid to use

[Jane]

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

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 ?

I also use these suction tools they are very good.

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.
