Well i don't know it is or not a dum question, but i was wondering what one would have to do to get a Wallaby with 65000 colors. Is it a hardware or a software issue?
many thanx
hardware
,,,
meaning a compatible display , right .
the display used is only 4000 or something colours
software cant change the limitations of the lcd
1 lcd displays have a connector
2 an electrical interface
3 and a signal protocol
4 and physical measurements
if a replacement with 65000 lcd display which
was compatible in all these 4 areas was avaible
then i suppose it could work
never heard about anybody doing it

I have replaced a lcd display a some time ago. The replacement LCD was working fine, but after a few months the replacement lcd display is showing a strange and wrong color gradient. It looks like old 16bit colors...
My hardware related question, could this problem be cable or lcd or mainboard related?
Yikes. I'd suspect a physical issue with the display. What do you see when you connect to an external HDMI screen?

When the hdmi cable is plugged between tablet and my tv, there is nothing wrong with output.
Today i have replaced also the flex cable, that did not help either.
Could the problem on lcd dispay be fixed? :'(

I'm speculating on the damage being with the LCD. I'm an IT professional (20+ years), so I do have a bit of experience here. One thing that's concerning is how the screen is separated, vertically, into the four bands. LCD screens are ridiculously delicate. I know from experience, having broken mine when replacing the digitizer glass.
LCD screens are typically very difficult/impossible to repair. It's cheaper/easier to just replace. I know this sort of sucks. Perhaps you can buy a replacement from a vendor that has a decent return policy. I'd use rubber gloves to handle the replacment (no fingerprints). Temporarily connect it. Problem gone? Then it was your LCD. Problem persist? (unlikely). Repack and return the replacement screen.
Good luck.

OK I have ordered a new lcd display, lets hope this will solve my problem.
Thanks everyone for your reactions.
Hello,
my Samsung Galaxy S4 has a green vertical 1 pixel wide stripe all over the screen since 3 days. I already reset it and it is definitely hardware related. Is there a possibility to deactivate the faulty pixels in the rom or kernel? I mean at some point there must be code that receives a pixel position and color and then activates the transistor int the TFT with a voltage. Does anybody know where I have to look? I guess anything that has to do with the LCD control. :good:
Hi,
A friend did buy a leeco cool c103 on my advice. Device was taken care of and was only dropped once in a case(it has no visual damage at all, still looks brand new). It still has the screen protector on it and the sticker on the back but now somtimes I see horizontal lines all through the screen, it started with backlit flickering a like 4 or 5 weeks ago(not really sure)
I personally think its some chip dying or because of a shock that caused a chip bga chip to get a poor connection.. Like a cracked solder ball, maybe theres no underfill under the chip ?
Did somebody else had/or is having the same problems/symptoms? Is this a sign of pre hw failure?
Device is not even a year old. The person who uses it doesn't do gaming and heavy multi tasking, always used the original charger etc..
Can somebody give me more details on this or is my friend just having bad luck with this device?
By the way it was purchased at AliExpress. Runs the last EUI 5.8.018S (Stable).

As some of you know, my vince got shattered and I'm going to replace the display & touchscreen, I was also thinking to switch my earpiece too becouse I damaged it somehow.
So the question is "Which is the best hardware parts for this device?"
By that I mean which of the many displays vince has is the "best" one, basically one that does what a display is made to do, WORK
Is it the novatek one? or the tianma one with no screen-retention s****. I need an answer as quick as possible so I can switch my device's display, thanks by now
Hi!
I have a PX3 unit with MCU HA 3.40 (not a dasaita one, maybe a clone) and it has 6.2 screen with a 800x480 resolution. I "got tired" of this screen, it is small, I am getting older , and I would like to replace it with a bigger one , 7 inch or 9 or 10.1 and with better resolution of course, 1024x600. I can made mods, I am just asking for some advise and sourses of knowledge which is plenty in this forum and thanks in advance for it!
I removed the front panel of the HU. It is connected to the main board with a ribbon. The front panel has an electronic sircuit and the lcd and touch screen is connected to it. I found that the lcd panel is 60 pins and the touch screen is 6 pins. On the back of the front panel there an electronic panel with the circuits and chips of the physical buttons (not touch buttons) and there is also a 40 pin connector (empty) and the lcd screen has a 2 pin cable with red and black color.
I saw some youtube videos of disassembling some new cheap car units with 1024x600 resolution, one with a 7 inch 40 pins ribbon and one with a 10.1 inch 60 pins ribbon and the 2 pins cable. So am thinking either of buying one of them and replace all the front panel or buy only the lcd and the touch panel and make a new "cover" for my car unit .... I don't bother with the physical buttons, I 'll find a way or modding them... But I have some questions:
1. Are these lcd panels and touch screens of the new cheap car units combatible with my unit?
2. Is my 40 pin connector working on MY unit or only the 60 pins one?
3. Is the 6 pin touch screen a "universal" common interface for these car units?
4. What is this 2 pin red/black cable? power for what?
I attach some fotos of my unit. Every suggestion is welcome!

Reply with an update if you sent ahead with the screen swap. I'm also curious if they are cross compatible? I have a 9inch 8227L Demo and the gps antenna wasn't working so the seller sent me the same model headunit but with a 10inch screen and upon hooking up the 10inch, Amp chip wasn't connected right or it was faulty. Anyways my plan now was to swap the 9inch working headunits screen with the 10inch. All the connections look the same and if I can swap out the board from the 9 and put it in the ten I will. I just haven't found to much info about it I can or not... Another idea I had was maybe try to disconnect the amp chip from the 9inch and solder it into the 10inch? Do you have any ideas if either of those ideas would work ?
Thanks in advance!
Have you tried to re-solder the pins on the amp?

No I've yet to try that. The reason being is because it looks as if the one pin that wasn't touching the board (or soldered incorrectly to begin with...) Shorted out and that pin/leg looks a little burnt now. Also it looks as if maybe possibly there wasn't enough Thermal Conductive paste too?? Just a guess though. ?
