50"+ TV Safe Matrix removal ! How ?

[web5]

So my 50" tv has no backlight, but operate normally and flashlight test - OK
Tried to find local TV service, and all afraid of braking TV matrix since it's bigger
that 40".
Question:

- what the best/safe/secure way to remove and then place back this
delicate part of TV without braking and leaving marks ?

Thanks.

Have an area set aside for the panel and diffusers to be placed carefully and if necessary cover to keep dust off. Remember the order things go back.

You can wear latex gloves to minimise finger grease.

Have two people to remove the panel. Do not flex.

shopjimmy have a video on removing a large panel on Youtube if you search

I've never lifted a 50" panel so this is only what I have read / viewed

some people also mention about using thick paper slid under the lcd panel then two people hold the paper and lift the panel up like a stretcher to spread the load i guess

i have done 47", hands at equal distance along top of screen and lift to stand on the frame, as if it was on a hinge, then slide hands around to sides and pick it up, replace the same way.

Most important. I just did one and almost made the mistake. Make sure panel goes back in frame seated all the way around. Especially at corners. Do not force it in. Shift panel around till all parts of panel seat at bottom of frame.

Why and how the fuck are a tv shop scared of doing a job, I repair them from my moms fucking bed room and not cracked one yet lol its easy just pinch the panel between your fingers when youve lifted it from the frame and set it down. Also I tape the tab boards to it as well to keep them out the way.

I lean the TV against the wall and tilt it forward until the loosened panel starts to fall forward. Using COTTON gloves, lift the panel away from the frame and store it leaning against the wall vertically. Do NOT try to lift the panel with the TV flat - the panels aren't strong enough to support themselves from the edges - I learned that lesson the hard way.

I have two pair of double cup suction grippers, but I haven't had the nerve to try them with a flat panel.

I had a thought about using SuckGrippers, but afraid it will suck in and brake
the thin LCD.
Is 1mm LCD is hard enough to stand Vertically by itself ?

Just had another conversation with tv service, and
they goes insane on me when i said that will try to take by myself.

Taping - good, saw on Tube.

I have an idea:

- when tv laying on the back and stripped to the lcd screen i
put 35" board and then tape it to the screen around borders.
- It should give solid non-bending surface and some grip for the hands.
- after fixing led i would just safely remove the tape and clean it.

Will this work ?

Yes... I've successfully done quite a few with this method.

The front surface has a thin film polarization filter on it. The tape may damage it.

How its done in the factory, do they use SuckGripper to install those lcd screens ?

I've used a pair of 4-head vacuum grip the kind they use for moving sheets of glass on a50" with success. My Buddy had to help me as it was a2 man job. I bought these from Northern Tool for 20.00, especially for this job. It was a good investment.

Nice, and how was it felt:

- like usual safe work with a thing glass or
- lcd could crack at any point

I wonder about the suction in the heads - isn't too much ?

Re: 50"+ TV Safe Matrix removal ! How ?

I took a chance and was successful. It will work for you too, as I feel the manufacturers of these suction vacuum tools must have considered very thin glass as well. The vacuum attachment of effortless on the glass.

This is the site. I couldn't post a link. They are in the US and prices are really reasonable.
Hope this helps.

Found the reply to "Grip 4-Head Suction Cup Dent Puller":

- I bought 2 of these Grip4s I would be using these to lift LCD screens off the panels to repair failed backlights. Some screens as big as 80ins. Did a 32in repair, lifting with 1 puller only. IT WORKS REALLY GREAT!! Thank you for this wonderful tool. I will definitely buy again from you.
