prob with sharpe of dash and dww-700m

patz · 05-12-2005, 08:47 AM

i got prob with dww-700m, because of the sharp of my dash
check the picture

black is the best position (for me)
green is default position (after opening)
but when I open it, screen motor stop moving (because of dash).. but will stay here (red)
(so I use button for move screen to black position)

but when I close screen and open it back, it goes at red position

so, I think the screen does not resume last position when it's stopped during opening ?!

I don't think motor will work for a long time.. (open, jammed because of dash, close, [...] every day)

somebody get this prob too ?
idea how to get screen go to black position when opening ?

sorry for bad english

there will be a contact switch on the side rails inside the unit defining in which position motor should stop ejecting screen (i.e. green position on you picture). chances are you can adjust the position by relocating that switch somehow.

No, it works with an encoder counting the motor rotations.
Beleive me, i understand mine well after the hours i put in to get it working.

**** ..

do you have a workaround..
each time I eject my screen.. i think it's the last time it will be ejected

mine is very irratic about it... sometimes it will hit the dash, and sometimes it will just stop in the last position.
Does this thing work with some sort of volatile memory ? (thinking of this since i don't leave it powered when the computer is down)

*bump*

Anybody got some input on this, i wouldn't want to fry my screen-motor

Thanks

I find that the screen returns to the exact same spot as when it was retracted. Does your go to a different position.

Are you guys keeping the power wires powered, and just switching the accessory wire to get the unit in and out, or are you removing power completely from the unit when you turn the car off?

tagging along to learn about this as I think this might be an issue for my next install

John_Duh · 08-22-2005, 12:54 PM

for the moment i've got it hooked up to the PSU, i.e. not constantly powered. (i'm going to resolder that over weekend)

Normally, when i open my screen it either hits the dash or stops one position further than my last opening position. I would say it's about 25-75% split between what it chooses, but so far i haven't been able to figure out a logic behind it.

I have a feeling it may be due to the loss of power.

If you can test it with constant power connected, and just switch the accessory, and let us know how that works.

You might want to slide the unit out, open the unit, set it where you want it, and then remount the unit in the DIN opening.

Mine opens to the same location every time (well, when I tested it at least)

mhhh ... Guess this weekend will be spent fidling with the screen.

I'll post my findings monday.

John_Duh · 08-29-2005, 02:12 AM

a lil update.
I've been rewireing my screen over weekend and it now has a constant 12V feed. I opened and closed it a lot and it returned to the same position. So i believe i've found an answer to the problem.

Also if you want to wire your screen like this, make sure you do the light mod on your screen so that your dash doesn't look like a christmas tree when parked.

Glad it worked, I thought it would.

And you should definitely do the light mod.

just one thing i'm wondering about. Now that it's constantly powered how much drain will that have on my battery ?
The main reason i didn't wire it like that in the first place is that i didn't want the extra battery drain.
