My solution to Auto Power ON Lilliput screen - Page 13

DJSmiley · 01-30-2005, 12:53 PM

Done the power-mod myself too.

I also have a later revision of the Lilliput, same as PHC, with 5 instead of 4 resistors. I also had some problems with the front-buttons, which didn't work anymore after putting my screen back into 1 piece.

Also made some pictures, since the previously posted pics weren't that good focussed. (However the resistor isnt focussed well on the first picture, using macro on my cam with additional lenses gives a VERY small DOF. (Canon A70 with +5 macro lense)

I used the 150k resistor as in the first post by Coyote. I saw PHC used another value for the resistor, but I stuck with the original mod and it works for me.

The flatcable to the front, for the buttons, can be connected in 2 ways. You have to connect it as on this picture, so its aligned at the left side. (See the space at the right side of the ribbon)

Coyote,

I had my Lilliput apart for another project and decided to try your mod. Took less then 5 minutes and it works great. Helps to have the right parts and equipment on hand! Thanks for sharing!

I don't remember exactly which is left or right, but you have to put that flat ribbon cable closer to the IR sensor. That is how I put a note to myself when I put the darn thing back.
By looking at the picture, if the IR sensor is to the right, then you have to move the cable to far to the right.

Well, on my photo the IR sensor is on the left, so the pic is made in WORKING state

(the small part of the black thing on the left is the IR sensor)

Done the mod, it works... I'm VERY happy!

I was looking into doing this, however I seem to have found another way

I just used this circuit and it worked great! I am mounting the monitor flush behind my double din dash opening in my mk3 Supra and I will not be able to reach the buttons so this really helps me out! Thank you very much!

<Echo>Anyone done this with a new 8" lilliput yet?</echo>

looneeii · 03-21-2005, 11:30 AM

Arathranar I'm awaiting the same info....

SOS · 03-21-2005, 12:02 PM

Did this on 2 7" lilliputs, worked perfectly!

looneeii · 03-24-2005, 07:51 AM

Kinda off-topic, but as an alternative how would you solder an external on/off switch to liliput instead of leaving it auto-on because I don't need to drain my battery the way I have it setup in my GP. Thanks.

Use a relay to switch the batteryline on/off from the ignition key...

HUH?

FYI - Mod made simpler.

By leaving the resistor in, I've added just one 150uF capacitor and it works fine.

Getting a 150uF cap is tough, especially one that is not huge. I found a 6.3V one in DigiKey that is pretty good.

Arathranar · 04-01-2005, 12:58 AM

Cool!

But has anyone tried this with an 8" lilliput yet? Last time I tried to mod something based on a 'similar' model, I ended up buying a replacement hud.
