Any helpful advice out there, please?
I drive an AutoSleeper Nuevo 2009 and the electronic control panel has gradually dimmed to a point where I have to be right up against the display to see anything at all. Off to France in three weeks so I'm a bit nervous about it. Auto Sleeper have suggested removing all leads to it - sometimes it kicks the unit back to life.
I was hoping for something more scientific so I'd welcome any tips on this. It looks a very expensive item to replace, and I'm just out of warranty.
I've changed the 3v integral battery with no result.

Ken.

nothing to lose by disconnecting it Ken.

seem to be a common fix with a few electronic panels.......including the dash board instruments on some ducato's :Eeek:

you will need to remove ALL power.

Could you not just disconnect the batteries? seems much similar and will take off all power,

you could, but it may also be connected in some way to the engine battery so that too would need disconnecting......make sure you have your radio code if needed.

you also need to remove the internal 3v backup battery as well so may as well pull the plug at the same time :thumb:

Ken.

It's scientific enough, powering down the little computer causes it to reset when powered up.

If the job had been done properly there would be a hidden reset switch as you find on nearly all phones/laptops/tablets.

Thanks for all the reassurance, folks.
I've removed all leads to the unit, including the 3v battery - and replaced them. But no joy - still very dim. The unit works fine - could be a failing display, I reckon.

still very dim.
Ken.

I wonder what you mean ?

Dim as in little backlight or dim as in little contrast.

Most LCDs have a contrast control, either a variable resistor or done in software.

Backlights are sometimes controlled in software, dim at night sort of thing.

Not sure how to reply to that one, Brian.
Naturally, the unit dims to nothing when not being used then a touch on the screen brings it up again - as you'd expect on any touch screen.
But at it's brightest, it's unreadable. We're talking face against the screen to read anything.
And no variable adjustment anywhere to bring it up again.
I'll try to find the manufacturer for a clue.

Brian, After some mental reasoning! - I've realised that it's the back-lighting which has failed.
Next step, find the manufacturer, I guess.

With 3 possible types of backlight you are right, it's getting beyond hints on a forum. If you have any local laptop repair places they should be familiar with the technology.
