Applying LCD Engine JX-V2959 V2.1

Recently I bought an Universal LCD Engine for my broken Dell monitor. The reason I bought it because it was cheap, the total price with shipping around 150.000 IDR from local online store.
 

The LCD engine type is JX-29-GS shown on the sticker, on the board it says JX-2959-GS V2.1. The first thing is to attach the LVDS cable connection. The LCD display type is MX150NX07. 
For reference you can follow description from https://sites.google.com/site/lcd4hobby/home .
Re-arrange the LVDS cable according to LCD based on the pinout shown in datasheets.

 

 
The left one is LVDS Pinout from my lcd display and the right one is LVDS pinout from the LCD engine. Next one i need control to my LCD engine, so i follow the schematics for IR receiver on a breadboard. I don't assemble the key yet.
 

 

The hardest one is to get the backlight come up again. There's universal lcd backlight inverter available online, but i think the price is ridiculous, some almost the same as the price of the LCD engine itself even more. So i go to aftermarket bought used laptop inverter, for 100.000 IDR i got four, no guarantee they still functionally. 

Follow the step from this link to get the inverter work: https://people.xiph.org/~xiphmont/thinkpad/led-inverter.shtml

So the hardware is complete, connect them all, put a batteries in the remote and plug the remote and voila... the monitor is up again and it has a TV Tuner and HDMI input. But I'm not happy yet, because the picture is cropping, only some part is shown. Then again the firmware need to be replaced with the appropriate lcd display.

From the LCD4HOBBY link above, we got TSUMV29 firmware with R840 tuner. Seeking the same type of my lcd i got firmware with folder name TUNER840_PNL_AA150XN07_1024X768_SI8L_3V_7KEY_EXTERN_LOGO_IR_KW_G32_LL140915_LAMV29

Copy the LAMV29.bin to flashdisk, rename it to MSTFLASH.bin, plug to the LCD engine and plug the power. The led will blink for a moment and then power up by itself. Hurray.. the resolution were perfectly fit, the TV work, HDMI work, VGA OK.. But wait... Where the sound goes?.. it silent as a tomb. Try changing various firmware got no luck.

The problem should be somewhere near the Audio chip. The type is NS4263 and from the schematics

i made simple modification to cut the resistor from SD (shutdown) and jump it to ground.

 

All sudden the room is fill with tv sound, ha ha... my project is complete. :))

For a moment i fell satisfy, but then i wonder how to put it all on the old monitor case...

I guess that should be done another time .. ))

 Here's my backup firmware link, remember to modify the sound chip if you use this on jx-v2959-gs v2.1 lcd engine.
