X220 FHD Upgrade?

Re: X220 FHD Upgrade?
Thanks to all who are helping.
When originally soldering the PCB I applied no-clean flux.
Just in case, this morning I resoldered (actually just heated up with my soldering iron until solder became liquid again) all 7 PCB dots and the power wire (but not the sense wire, too 'sensitive' a location).
I rechecked again with my multimeter that there are no false contacts.
Next question:
in BIOS LCD settings there are 5 options:
- Thinkpad LCD
- Analog (VGA)
- Digital on Thinkpad
- Digital 1 on dock
- Digital 2 on dock
I tried them all, but which one should I use?
PS: I have plenty of soldering experience after having done nearly 100 SATA-mods and over 100 LED-mods.

FHD display corresponds to Digital 2 on dock, but there's no point selecting it until you get the image on it.RealBlackStuff wrote:I tried them all, but which one should I use?

Re: X220 FHD Upgrade?
Thanks.
Using Lenovo Diagnostics on that X230, when I do the LCD test I get this:
- Manufacture ID: LGD
- Model: unknown
- EDID Version: 1.4
- Max resolution: 1920x1080
- Max image size: 28 x 16 cm
- Display type: RGB 4:4:4
So the FHD screen is recognized somewhere!
I'm doing this LCD-test using the attached external monitor (a 15" XGA NEC, 1024x768, got there with Fn/F7), while the backlight/screen of the FHD are OFF. Huh????
Should I already set the Dock 2 option?

Re: X220 FHD Upgrade?
Dock 2 option should be used to choose new FHD display as primary display. That means when FHD is connected and you connect external monitor, you won't get image on external monitor when booting. By default, external monitor is used instead of internal. So, there's no point to change that right now.
Which OS do you use right now? I suggest we stick with Windows so that I can understand what are you doing.

Re: X220 FHD Upgrade?
OK, I've set the BIOS display back to Thinkpad-LCD.
When I boot without HDD, the X230 goes automatically into the Boot Menu/Application Menu.
The above Lenovo display test is part of the: Application/Menu/Lenovo Diagnostics.
I am using a HDD with W7Pro/SP1 in 32-bit.
If I boot into W7, the Fn/F7 no longer functions and the FHD stays off.

Weird, can you see if the image is shown in the FHD when the backlight is off (you can see it with very clear ambient light)... It's that W7 working when you connect the old PANEL?

Go to Control Panel\Appearance and Personalization\Display\Screen Resolution and see what displays you have.RealBlackStuff wrote:If I boot into W7, the Fn/F7 no longer functions and the FHD stays off.

Re: X220 FHD Upgrade?
@carcuevas:
The old IPS screen (and W7) still works fine if I connect it instead of FHD.
@nitrocaster:
The Lenovo LCD-test is part of the X230 BIOS.
As I already mentioned, the "1920x1080 test-result" was displayed on the external monitor, while the FHD was off.
(Can't have both on at the same time).
In the meantime I have installed the Intel GPU 4000 drivers from Lenovo (g1d556ww.exe).
(The drive with 32-bit W7 just had generic Windows drivers installed)
Makes no difference (yet).
In Control Panel I have no Appearance, only Personalization (also accessible in W7 by rightclicking the desktop).
When I go into Display it shows THREE displays:
1. Dummy display
2. Display device on: Mobile PC display (presumably the FHD)
3. FPD1975W (External display with 1440x900, swapped against the XGA)
3. is the big one.
It also has a field:
Multiple displays: Extend desktop to this display.
Both 1. and 2. have greyed out Resolution/Orientation, and
Multiple displays: Disconnect this display.

So, it is recognized.RealBlackStuff wrote:2. Display device on: Mobile PC display (presumably the FHD)
Your display configuration should look like this ('Dummy display' and 'Mobile PC display' are duplicated): http://imgur.com/WXqEtWY
But you should have got an image right after the first start. Something is wrong. Let's troubleshoot it this way.
0. Disconnect all power!
1. Disconnect old display and reconnect new FHD display
2. Connect external monitor
3. Power up without hard drive
4. Wait until you see an image on external monitor
5. Using Fn+F7 try to get a backlight on FHD display
6. Check if you can adjust the brightness

Re: X220 FHD Upgrade?
That means there is no video signal going to FHD panel (on the motherboard side). Or, that could also mean that you choose fake LVDS display and not FHD.RealBlackStuff wrote:both .5 (backlight) and .6 (adjust) work
If you boot with FHD and external monitor, does Windows allow you to use 'Extend these displays' option over 'Mobile PC display' and external monitor?

They are grayed out because they are disconnected.
Choose 'Duplicate desktop on 2 and 3' here: http://i.imgur.com/DcbZRHT.jpg

Re: X220 FHD Upgrade?
If I select Mobile display and Choose 'Duplicate desktop on 2 and 3', the upper Display field changes to: "2/3 Multiple Monitors"
And when I try to Apply it (or save anything) it says"Unable to save display settings".
While I'm trying any of this this, the FHD backlight stays on all the time!

Re: X220 FHD Upgrade?
I got similar results with isolated data lines (DOCKB_DP0 and DOCKB_DP1), but without backlight on FHD display. Windows does recognize it but can not save display settings.
Check continuity between 4 solder points corresponding to DP0/DP1 and display side connector on the eDP cable.

Re: X220 FHD Upgrade?
Both upper-left and bottom-left in that circle do not even connect to the LCD-connector on the PCB!
All other 5 7 solder-points do.

Re: X220 FHD Upgrade?
They should go to pins 6-7, 1 being top left. Do those pins look correctly soldered on the connector ?

Re: X220 FHD Upgrade?
Correction:
All 7 solder-points do connect to the LCD connector.
But both upper-left and bottom-left in that circle do NOT connect through to the LCD-connector on the LCD-side.
Then I checked the LCD-cable itself.
That has the same problem, so I think the LCD-cable may be to blame.

Re: X220 FHD Upgrade?
Well actually it can be the EDP cable, because if it would be the LVDS at least you would be able to see the screen images without the Backlight as it happened to me...RealBlackStuff wrote:Correction:

Re: X220 FHD Upgrade?
Those 2 pins 6 and 7 do NOT feed through the cable from PCB to LCD.
I have the LCD-pinout but not the PCB-pinout.
So what goes where in that cable?

I guess you measure that with FHD LCD connected to the adapter board, right?RealBlackStuff wrote:Those 2 pins 6 and 7 do NOT feed through the cable from PCB to LCD.

First 11 pins match on both ends, so pins 3,4 on the board side must be connected to pins 3,4 on LCD side. Similarly, pins 6,7 and 9,10 on the board side must be connected to pins 6,7 and 9,10 on the LCD side.RealBlackStuff wrote:So what goes where in that cable?

Re: X220 FHD Upgrade?
After trying everything, in every direction, with or without LCD-cable, pins 6 and 7 do NOT connect to the LCD.
So it's definitely a bad LCD-cable.

Re: X220 FHD Upgrade?
After getting backlight working on the stock display, there's still no backlight at all on the FHD display. It seems to work otherwise, it shows a picture. I managed to destroy the pad on the adapter board that goes to DOCKB_HPD. Could that be the cause?

Re: X220 FHD Upgrade?
Are you getting no backlight in the OS only or in the BIOS too? Might be fried MCU on the adapter board - it happened to another user when he hot plugged one of the LCD cables.
Re: X220 FHD Upgrade?
No backlight in bios.
