Quanta BL5S (DABL5SMB6E0) "Discrete" to "UMA"

**************************************************
Brand: Toshiba
Model: Satellite A300D-16I
Motherboard: Quanta BL5S, DABL5SMB6E0, Rev.: E
**************************************************
Hello!
I'm working on the mentioned laptop, which does not show the image on the screen. It turned out it is bad the GPU chip (on the separated graphics card). After the diagnostic heating of the GPU the video returned, but the client doesn't want to wait for a new GPU chip. I decided to convert the motherboard from Discrete to UMA, with the client agrees with.

What I've done up to now:
RN18 -> RN9
RN17 -> RN8
RN16 -> RN7
RN14 -> RN15

RN19 -> RN10
RN20 -> RN11
RN13 -> RN6
RN12 -> RN5

R419 -> R420
R4 -> R5
R468 -> R465
R469 -> R466
R402 -> R600
PR34 -> changed value to 10kΩ

BIOS chip U2 reflashed with this dump.


Now after pressing to the power button the LEDs and the fan turns on, but there is no video and no backlight on the screen.
Have I missed/forget something?

Are you sure you have GM version of north bridge? PMs don't have an integrated graphics.

Do you have NB with GPU - GM version, not PM?
If yes than missed:
add RP41, RP47 -> RP42, add R451, R454, remove R452, R456, add R116, R124, add R81, R82 + capacitors C63/C64 ... + remove R74, add L36 + C489 + C492 + C491 + remove R130, add R457 + C153 + C482 + remove R455, add R109 + D8, and many others for CRT/HDMI/TV
Please search on schema: IV - internal video (should be add to MB) and EV - external video (should be removed).

IMO, better to search for IV@ and EV@.

EDIT: Nevermind - you have a PM965 chipset (and you can't have A300D model as "D" means AMD-based):

Yes, the North bridge is LE82PM965 (SLA5U)

Thanks to both of you for your help!
