The points on PCB back of the Socket, are points where it's supposed to be soldered.

Solder -ve wire from the Leds to Gnd & +ve to +ve ...

NOTE: My pass light wasn't working after this mod !

I tried that points , but it didnt work perfect as it was on speedometer before adding led strips

I mean to say if we connect the led strip wires to the points mentioned by you in previus post
then
when we switch on the bike by inserting the key and turned it to 'ON' position, then these led strips didnt get current from these two points..
See the below video for feature i m talking about

Led strips works only, when i switch on parking lights..

But i managed to get that feature also working with the help of my friend by identifying some other points on pcb using volt meter.
It took almost about 5 hours for both us to complete all these procedure including assembling and dissemble the meter.

Result :

Re: Changing Backlight Colour of LCD Speedo Console: Pulsar

So at what points did you solder the cables ??

I didn't take the picture of pcb while connecting points ,
but i m going to open again meter in a day or two for some slight modification and then gave you snapshot,
but if u have any picture of pcb, then send it to me, I will mark the points for your need...

Hello Rahul. I have my brother's P220S Dtsi of April 2010. After an accident the Speedometer was replaced by the SVC with a P180 meter (White dial). Since I wanted the same speedo face of 220, I picked an used speedo from OLX. Also my brother wanted a blue illumination after being inspired by your post. It was working while I bench tested. Unfortunately due to a lose wire from my test bench some how touched something in the rear side of the board. After this incident the illumination is dim during key ON and the display completely vanishes with park light ON. I only suspect a small diode or resistor got busted and it highly restorable. It would be great if you are someone who is conversant with the schematic of this display unit could help me resolve the problem. Or if anyone has a old working but broken unit, I am willing to buy the same.

Re: Changing Backlight Colour of LCD Speedo Console: Pulsar

Okay its been more than 18 months i guess since i did this MOD (thanks to rahuldevnath). And now all of a sudden i am facing this issue with my speedo console.
It doesnt show anything when the ignition is turned ON. The rpm needle too is dead.
The only time the LCD display goes on is during the first boot (after unplugging the cable connector and re-plugging), and then it dies again. The LCD backlight is working though.
I opened up the headlamp assembly to pin point the issue but after spending 2 hours i was left with nothing. All the connectors and wires leading to the speedo are connected and intact.

So, i wanna know if any of you guys experienced a similar issue and what would be a possible solution to this?
I read from other threads that changing the speedo cable might...might be helpful.

Re: Changing Backlight Colour of LCD Speedo Console: Pulsar

after 1 year... this is the last view of my speedo console P220F.... sorry I didn't take any picture while progressing this project... hope this can improving your skill to modify your console

FYI for the LCD display i using inverter LCD layer so the view for LCD become opposite from the usual... got this idea while i'm watching my mom's cooking clock alarm.. hehehe

Greetings to all.

Lately there have been many questions being asked about changing the backlit colour of LCD consoles. It was also one of initial idea modding, about 3 years back. Finally I decided to take the risk of altering a 3K worth Unit!

I decided to put up the thread in Desi Bike section, simply because we can discuss here, share ideas and can help each other in modding other bike's console.

Also Note: It's not advisable for a normal user to tinker with the cosole, unless you are ready to take the risk or very proficient and confident with your fine soldering skills.

So here we go.

Step 1:

The First and foremost step is to remove the unit from the bike. Detach the wiring from the back of the unit, and remove the screws marked in red.

Step 2:

Now, after removing the cover. Remove the screws of the (1) face plate. (2) Pull the Tacho Needle straight and (3) Push Button Plastic Link

Step 3:

You can see in the picture, three parts of console you are left with.

Step 4:

Turn back the PCB LCD Unit.

This one of the most crucial part. You need to carefully De-solder the LCD points from the PCB Unit. It's important that each and every single point is absolutely free (check with the twizeers that every point is freely moving.

Remove the LCD Panel. Even a slight extra force can damage the LCD unit, so be careful.

Step 5

After removal of LCD Panel Unit-

(1) Red Area Marked LEDs are the backlit for LCD.
(2) Blue Colour Marked LEDs are for the Tacho Unit.
(3) Green Marked LEDs are for the needle and Over Rev/Low Fuel Indicators (meant to untouched)

Step 6:

Attach a 12V supply to the PCB to check the functioning of the LEDs (before and After changing of LEDs

Note: Different version of Speedo Consoles have different setups.

Step 7:

Here Comes the most important part.

There are two ways to change the backlit.
(1) De-Solder the existing LEDS and replace them with your preferred colour.
However from experience I found out that even little heat damaged the PCB. After replacing the LED, only few of the replaced ones got lit.

I double checked it and found the solder to be fine, but for some unknown reason some were not glowing. So next step was for "The Great Indain Juggad"

(2) Remove the existing LEDs and paste strips of LED. These Strips have resistors inbuilt to work with 12Vs and paste over the PCB area.

Note the removed LEDs on the Picture

Step 8:

If you are successful to change the LEDs than you are done. But with the Jugaad method, you need to connect the wires to draw power when the back-lit is supposed to be on.

The points on PCB back of the Socket, are points where it's supposed to be soldered.

Step 9:

Results:

Cost Involved?

1 Meter Strip of LEDs : 300 Rs. (The minimum i got from wholesale dealers)

Tools?
Screwdrivers, Soldering Iron, Solder,Flux De-soldering Pump and wick and wires.

Edit:

For warranty conscious people, thanks to Omi's idea :

We can stick Black tape on existing LEDs and install the new LED strips separately.

Hi Rahul,
