Hello!

Since I've noticed that YUV output (both progressive and interlaced) generates far more better image
then any other output (except VGA...) I wanted to have it on my mostly used MTK player: Philips
LX3900/01.

This player has scart/svideo/cvbs output but not YUV.

As we know mtk firmwares for Y, U(Pb), V(Pr) uses the R,G,B pins.

The the idea was simple:

If the player switch to YUV mode then YUV signal will be on the scart RGB pins and we have to
connect this pins to the TV's YUV input.

The solution has two parts:

Part 1:
-------

I bought a Scart -> 3 RCA converter (was designed for scart -> cvbs + stereo audio) and changed the
pins and make a common ground on scart pin 4.

The standard Scart pin layout:

 7   RGB B_lue Signal
11   RGB G_reen Signal
15   RGB R_ed Signal

From the Philips LX3900 service manual we can figure out that

Y = Green
U (Pb) = Blue
V (Pr) = Red

So I changed the pin connection inside the "converter" and make a common ground on Pin 4 (since
Philips service manual says it is GND_Scart).

That's all: Scart -> YUV converter ready.

Part 2:
-------

Have to patch firmware to switch to YUV and be able to turn on Progressive Scan too.

I was lazy to create new setup menu items and better (in case something goes wrong) if I can change
tv output mode and p-scan with remote so I've modified the remote table for it.

After checking players that have PAL/NTSC, TV Mode and P-SCAN button we can figure out Remote
Command Code for them:

0x38 : PAL/NTSC/MULTI switch
0x3A : Component mode (OFF/RGB/YUV/VGA)
0x3B : Progressive-Scan ON / OFF(interlaced)

It can be put on any remote button but for LX3900 I've create new "Press & Hold" buttons for them:

press and hold
'1' for TV mode switch
'3' for Component mode
'5' for P-SCAN

---------

Tested and working properly! Now I have a LX3900/01 with YUV output too!

ps.

Part 3:
-------

For Philips players (DVP720, LX3900) additional patches to firmware must be added to enable YUV output
