Question Jumper Technology Ezbook x3 LCD

[Techiehobby1]

Anyone out there help me with my Jumper Technology EzBook x3, which requires a replacement LCD

I have searched the internet high and low.. including eBay, Amazon, AliExpress, but keep coming up with blank searches.

P/n is 133x56-501-0101

I can find similar replica style screens, however this LCD seems to have the 30 pin connector, BUT... also has a 10 pin connector along its strip on the back which is attached to the bakc of the LCD. I am guessing this as something to do with eDP to LDVS

My main question is... anyone know where I can purchase a replacement LCD please.

OR compatible one that is same form fit and function

Many thanks

When dealing with panels I use panelook.com to get the specs and cross reference them with other models.

@Tech Junky that is an awesome website.. i have never heard of that one.
I have managed to locate the spec of the LCD
However, the pcb stuck to the rear is not mentioned......
I have done a little bit more inspecting and noticed that its only stuck down with 3 black foam sticky pads so carefully lifting them up.
I have taken several pictures of the pcb and will continue my search.

Thanks again

Sounds like it's a touchscreen digitizer. Might be something else though like the camera assembly or some other interface on the other end. The 30 pon is probably the edp video cable though as the tend to be 30/40 pin. Lvds though is a bit chunkier and less wires.

The panel info though should indicate which edp/lvds is in use for output. There might be a service manual for the device that shows more tech info on how ots built.

@Tech Junky
I am fairly sure its not a touchscreen digitizer because this type LCD screen is only available for the 11.6" model, and furthermore I have the Intel Celeron Apollo Lake N3450.
From looking at various sites.. I am fairly sure I have the EzBook X3 model.
Just the back of the LCD does not tie up with any of the connector specs or additional TCON board etc.
On the back of the large pcb affixed to the rear of the panel and scattered about is the following silkscreen text:
SHARP
69B4AS
S822 6063-02
2-9 94V-0
E222034 1631
L1
K5746TP
LFa
*** also an IC with 90BL201 634498

There is also a second mini PCB (black in colour) affixed to the back of the LCD Panel which contains scattered silkscreen text:
INET P313-EDP-LVDS-C55211 REV12
2021-08-09
ROHS 2140
94V-0
QL-M E328832

I am really rather stumped. None of the above seems to match any records.

The Manufacture or Aftersales at "Shenzhen Jumper Technology" will not respond to any of my email requests either.

thanks again though and any extra help would be appreciated

Well, then I would focus on the panel itself and just port over the other PCB items to the new panel.

Instead of sticking them to the back of the panel maybe stick them to the lid or case.

Jumper EZbook X3 Review: Ancient technology meets wobbly chassis

We have tested the Jumper EZbook X3, a low-range 13.3-inch laptop. Its price of $250 including Windows rightly evokes suspicion.

www.notebookcheck.net

This gives a little bit of insight as the panel listed - PBTB133F006

This only really comes back with a dozen or so laptop models though. I would poke it with HWINFO and see if there's more tangible info you can suss from the output.

Free Download HWiNFO Sofware | Installer & Portable for Windows, DOS

Start to analyze your hardware right now! HWiNFO has available as an Installer and Portable version for Windows (32/64-bit) and Portable version for DOS.

www.hwinfo.com

It will give you info on every component from the parts themselves as Windows sees them.

https://rjtech.com/shop/index.php?dispatch=categories.view&category_id=220 -- These are mostly what I deal with at this point. Clevo is kind of unheard of because they don't sell in retail stores or pop up on a normal search but, they're great to work on / with. My current and previous are Clevo and they're kind of the open source version of a laptop compared to other brands as you can get the full service manual for them down to the circuits on the board level kind of info or in our case the panel options for the model. I took my model and upgraded it to a 4K120 from FHD on both laptops fairly easily using panelook for specs / model info. The current one though required an edp cable pitch adapter though to use the higher performance panel since AUO uses a different cable pitch than most other manufacturers for some reason. Not a big deal once you find it though since they're ~$5 to put between the edp / panel.

@Tech Junky
I have installed the HWInfo Portable.. however, because the screen is cracked I am unable to get any clear image.
How can I "poke it" (as you called it) with HWInfo.. as I cannot see anywhere on that program to manually enter data.
Is there a way that I can visually see what is on screen even if I cannot see the whats on the cracked screen.
Obviously.. I am thinking in lines of Screen mirroring, but I am still not 100% certain what machine this is at present.
So I guess my question is what is the best way to mirror view a laptop if I cannot see to access the laptops internal programs and select A SCREEN MIRRORING option

 

[Tech Junky]

Plug it into a TV w/ HDMI or something along those lines. As for the "poking", it's simply viewing the output of the program to get the actual model numbers or tech info from the system. Sometimes the stickers OEMs place on things aren't the actual info you're needing when trying to fix things.

 

[Techiehobby1]

@Tech Junky
I completely forgot about that idea. I will rig up the laptop to a tv in the morning, and see if I can pull any decent information from the laptop per your last thoughts
Thanks again

In the meantime, I am still struggling to locate a supplier for the LCD panels. I am situated in the UK but if it is necessary to pay shipping fees then that will have to be

 

[Tech Junky]

Yeah, panels can be a pain to source domestically. I'm in the US and have them shipped from CN or CA. CN ends up being cheaper though than domestic sellers that markup 150%. It all kind of depends on if it's worthwhile for the upgrade or repair. Jumping from FHD60 to 4K120 is worth it for me. Now, if your laptop is $300 and spending more than $60 on a new panel might not make sense. If it's higher end in value then it's worthwhile.

Funding something in the EU / UK though should be possible w/o too much extra in fees / duties.

@Tech Junky
Apologies for the delay in responding to you. There is a reason for my delay in response but I do not like to discuss over this thread.
So I have followed your advice, I have ran HWInfo and got so much information... what a program, its amazing!
I have attached a couple/few screen shots for your info...
I can confirm it is a PBTB133F006-A panel, and the laptop specs only state it being a Microbyte Ezbook, but don't inform of the exact model however, using the other information provided I can confirm that I have narrowed it down to the Ezbook X3 model (as I originally thought) but definitely was good to get clarification.

Now, the Panel in question... I cannot locate any supplier in any country that has this panel available to purchase, even ship overseas.
Nor can I work out a direct compatible replacement... therefore please can I have one more bit of assistance in sourcing.

Finally, whilst I am sourcing could you also confirm that this panel replacement will be close to true likeness... because the issue I am seeing is that the larger SHARP pcb panel which is (or was) affixed to the back of the panel does not connect to the panel via any connector, and the actual 2 x fpc cables are soldered (well I am sure they are soldered) to the SHARP pcb.
Might make a bit more sense with the images attached.

 

[Tech Junky]

Congrats!

So, the things I would look at are the video connector and whether the panel is screwed to the lid or not I see the hinge screws but, most panels are usually just double sided tape / foam these days.

Next is figure out the size diagonally with a tape just to get an idea of the physical size. The model number hints it's at least 13" but might be 13.3". Count the wires on the edp connector as it could be 30-40. From there you should be able to find something that fits on panelook that can be ordered.

I would consider bumping to a fhd panel for sharper graphics as well. Price difference shouldn't be much difference. The fhd option might be more rare depending on the size though. Sometimes odd sizes don't have many options.

 

[Techiehobby1]

@Tech Junky
Thank you again.
Its a bit of an odd one..I cant work out if its 13.3" or 14" < I work in CM or MM normally (another picture attached).
Its screwed to the lid.
I counted the wires and its definitely 30 wires.
From my understanding of researching this panel.. I thought it was already FHD.

 

[Techiehobby1]

@Tech Junky
Also, the measurement I took was placing the start of the tape measure to the outside edge corner.... should this of been measured where the outside of black tape (think its called shading tape) ends.. making it the visible screen size perhaps 🤷‍♂️

 

[Techiehobby1]

@Tech Junky
Furthermore... It just does not make sense..
The physical label on the back of the panel is as per previous image, yet when I input that into Panelook..the screen dimensions do not seem to tie up.
According to panelook the panel should be 13.3", yet my tape measures closer to 14"....Am I doing something wrong.. I will check with a straight solid Metal rule and see if its the tape measure that is inaccurate (although I can't see how)

 

[Tech Junky]

I'm going with 13.3' on this one

So, I would be looking at those and fhd / 30p / edp w/ mounting holes.

The one photo says it's 16*29cm so, convert that and you should get the size I inches.

 

[Tech Junky]

I would start with these.

Panel Specification Compare - Panelook.com

www.panelook.com

The concern though between them is the outer size and whether it will fit inside the lid.


Now, for me I would be looking at better color options as well but, for this size that means looking at the 4K options or at least having a 40p EDP cable. There are ways to convert from a 30 >> 40 cable but, the pinout isn't always a match on the active wiring.

@Tech Junky
Search results coming back with ZERO results


(EDITED) Ignore this reply.. I didn't see your second one highlighting the search

 

[Tech Junky]

If you click this https://www.panelook.com/modelcompare.php?ids=60154,43888,59959 it will have your results I picked out.

 

[Techiehobby1]

@Tech Junky
Thank you.. I clicked that link and can see your results.

However, I do not want to keep pestering you with message after message, but when I tried to replicate your results, the ones you have provided do not even appear in the list.
How?? did you get those results to appear.
Is it under the "CATEGORIES" then search for relevant screen size... or do you use a different tab??

 

[Tech Junky]

I picked the 13.3 size for starters then edp / 30p and sort by brightness. Brightness makes a difference as a lot of panels use lower brightness and make them useless unless you're in a dim environment. Then I customize the fields to show mounting brackets / outline size / etc.

[Techiehobby1]

@Tech Junky
Okay.. I have now managed to get the same list of 273 models as per your link.
What is the difference between Outline size and active size etc?

 

[Tech Junky]

One is the screen viewable size and the other is the physical size of the edge to edge measurement that fits inside the lid.

So, the 13.3" 16*29CM is the active / viewable size.

The outline size will come into play though as it might offset the mounting tabs that it screws into. There's not usually too much variance between MFGs but, sometimes there's enough to make you need to make adjustments to make them fit. Ideally you just want one that just drops into place w/o pressure. Being that your specific model doesn't pop up with specs / measurements it's a bit of a tedious task to take measurements manually vs just being able to pull them up for comparison.

@Tech Junky
Are you a Paid member to Panelook
Reason I ask is because those models do not share the 30 pin connector and the 10 pin connector. I cannot see a way for me to connect the 10 pin connector required to power the mini pcb

 

[Tech Junky]

10 pin connector

Does this plug into the panel or to an adjacent connector that goes back to the mobo?

Take it off completely and take a pic and see if we can identify it and what it does. The first thing that comes to mind is it's just a webcam unless it ties into the panel wiring.
