Thread: My solution to Auto Power ON Lilliput screen

first time ever touch the solder iron, when i solder
my excuter 2.3b with xbox v1.5
took me 2 hrs with the d0 points....my eyes are crapping out on me...
well i had good instructions.....
thanks...

Why not just hook the screen up to the yellow and black wire off of one of the molex connectors on the power supply?

And then do the auto-turn on mod????

Well because applying power to the monitor does not turn it on. You still have to press the 'on' button.

yeah thats really awesome!

I did it aswel and it works like a charm. It was kindof hard removing that resistor. What worked good for me was to take the soldering iron to the contact closes to me (in the picture) and once the solder was soft and molten I flicked upwards with the tip of the soldering iron.

Good Luck

Cheers

hi there,
does anybody know how i can solve this problem?
after autopower on the screen the computer boots and the screen adjusts to the resolution of 640x480 of the windows boot logo. when finished booting it doesent change to the res. of media engine wich is 800x600!
then i have to do power of and on the screen again and it works. is it possible to change the resolution of the windows bootlogo? then it has to adjusts to the bootlogo and is then ok for the mediaengine as well? how?
thanks for any help,
enzo

Base on the mod, correct me if I am wrong.
Coyote just replace a 10K Resistor with a 150K Resistor and add a 10uF cap.
From there, The cap stores the charge for 1.5 second and discharge (that simulate the "button press"). I think you don't have to remove that 10K resistor, instead just add a 100uF cap (that is 1 second). It probably do the same thing. Solder point is the same thing.
Is that correct Coyote?

Yes but the problem is that 100uF begin to be a big capacitive load and can generate disturbances to other parts of the circuit and is dangerous for the lifetime of the power button . I think that 10uF is the limit.

Moreover, the 150K resistor is also the limit to pull up the uC input to 5V with a good stability.

They are the reasons of my choice of values.
