So it's around 1.75mm thick with both protective papers still on. The 03 (on top) doesn't seem much thicker than the 21, perhaps 0.1mm. AFAIK w11 and w21 are pretty much the same. w15 would be a w11 with the plug on the correct side (some of the taobao modders use it).

This is the cable "management" for camera & others. Once you get it out of the way, the panel will sit nicely at the edge of the camera curve, resting on the bottom plastic square.

I'd guess the bleeding has to do with the lid trimming or cables.

Also, congrats on doing a 03. That was a pain, wasn't it ? :lol:

Note on serviceability : Take a picture of the pads before you put the screen in. You can slide a flexible metal ruler behind the panel to separate them one by one. My panel was slightly misaligned on the right and I fixed it by lifting it off on 5 of the 10 pads to push the screen down. You could probably remove the whole panel if you don't put too much adhesive and know where it is.

Hey Boutch,

How did you solve the cable length issue when using the W11 screen?
I ordered 3 W15's and they've all arrived as W11's instead, so obviously the connector is on the far side.

Cheers.

Couldn't find the right cable so I chained 2 of those. Works great, no interference.

Ahhhh I see. So that's what you meant by switchers then.

I ended to just adding in cable to make the original one longer. Works great now. I cut the bezel with a craft knife and metal rule, then finished with a diamond file. I do have a slight light leaky spot where it seems the bezel is pressing too much onto the screen. I'll have a go at that again tomorrow but super happy with the results.

Thanks for the info. :)

While removing the bezel, if the side clips are too tight, undo top & bottom first, then slide the sides ~1cm up or down to get the clips out of the brackets.

Oh I can pop them in and out easily enough. I think it's due to the gap around the screen being quite tight in the lid. I opted to keep the rubber bumpers on the sides of the bezel so I still have room to trim, if needed.

Just a warning.

If someone has, like me, the bright idea of flashing the screen to disable adaptive brightness, don't do it. :BAAAD!: (except if you find a way to take a good backup first)
Even if you did your research for 0DJCP6 part number, that matches the W21 and the 9350, it will just kill the screen.
I have a new one on the way, I'll try to extract an original firmware and patch it back.

Perhaps someone that bought a w21 could do an extract for me ? Using this driver from Dell, when running TCON_DP_REWORK_TOOL from the 9350 folder, there is a "Save Romcode" in the "others" menu. It prompts that it will update but it just extracts. Tested with a w03, still works ;)

Guys, any experience on the LQ133M1JW15 panel? Do I need to cut the PCB in order to fit the panel like the LQ133M1JW11? Can I even do it? (no circuitry like LQ133M1JW11)?

This taobao seller says "do not use: Chi Mei GP1 , Sharp w15 , Sharp 13.3-inch 2K screen". There's a mention of it being 0.5-1mm wider, you might end up with unequal bezels and difficulty with the side clips, they are already really tight with the w11/21.

Ok, but I wanted to avoid having to fit under the screen an EDP extension cable :(

That FHD board has a cable that's long enough (tested). I haven't found another solution yet.

Ok, hopefully the kits that I got have an edp cable long enough, otherwise I can always get this cheap edp extender.

Once superbuy confirms my order, I'll buy a LQ133M1JW11 screen. I've heard that it has a better color coverage than the LQ133M1JW21.

Would the LQ133M1JW11 need two extenders with the nitrocaster mod like the LQ133M1JW21?

What about the B133HAN04.9 screen, its outline dimensions are 299.872(H)×186.92(V) ×2.2(D) mm. Should fit, no?

Edit: Probably even better the B133HAN04.6 I think it is easier to install, since the led driver is behind the panel see here.

Now having both I can confirm that W11 and W21 are identical. That other screen looks a bit too high. It might be possible to unscrew the controller board from the support and flip it on the back of the panel though.
