Question about Vehicle Parts & Accessories

4 Answers

I no longer get a bright display. The display stays on dim even when I switch to bright. I cannot see the screen at all during the day. I have a Cobra XRS 9930 that has developed a very dim display. Pushing the display button tells me that I am on bright or dim, but the display is unreadable and unchanged. Any ideas?

    I 've a CobraXRS9985.

    I can not see the any visual commands on the rd.

    The display part# reads xrs9930 not 9985.
    This part is the display and speaker all in one part.
    My guess is that it over heated. burned out !
    Im trying to get the replacement part from radio shack.
    Is there any way to get a replavement part not radio shack?

    Thanks,

    my xrs 797 does this too, it got worse with time. Over a week the display got dimmer and dimmer until eventually it quit working completely.



    Still picks up radar/laser like a champ from impressive distances, but no display...

    I have exactly the same problem. I took my Cobra 9930 to an electronics shop where a technician found the color display deffective. OK at night (dim) but the setting doesn't work. I need to replace the display. Can you please help?

    same problem stays dim

    I live in Florida and it seems to a be a problem with heat.

    This unit display will overheat and shut down when temps reach 140 F plus inside the car. Try placing the unit in your freezer overnight. If the display is damaged it will probably work for a short time the next day and then go dim. Old electronics trick. Not much you can do if it is the display...maybe buy a new unit! Displays can cost between $15.00 and $30.00

The xrs 9930 is the same as the xrs 9985.
Cobra makes this model to sell only to radio shack.
My display went out!
I took the rd apart. Very delicate part.
The display part# reads xrs9930 not 9985.
This part is the display and speaker all in one part.

You need to go to user settings and switch the dim settings. i suggest you switch it to bright instead of dim in the user menu/settings. sadly this is answered by a 16 year old. =D.

Led display shut down when the detector detect an alert


You have the unit in dark mode. Press the Dim/Dark button again to get the unit to full brightness. THe unit has 3 levels of DIM. First the unit is at its full brightness, pressing the dim/dark button will dim the display and the unit functions normally. Press the Dim/Dark button again will futher darken the display but when the unit alarms the display is turned off and remain off during the alert. After the alert is over the unit waits 20 seconds of no alert to turn the display back on.

Even though it is plugged into power it still won't show any information. It worked one day , but the next day it wouldn't work.


I looked at the 9700's instruction manual, and I could not find any method for resetting the 9700 to its factory default settings. My guess is that the display has failed since there are several other posts for various other Cobra RDs where the display suddenly stopped working.
