Whistler 35R just quit. fuse and pwer cord is fine.

Usually there is a short in the system when fuse is blown. Check the cord as sometimes mouse can damage the cord. It is a posibility.
Check power to the electronic board.

You need to remove top and check for 12v and 5v,( put multimeter leads on wires one at a time) going into display panel from main board. If you see 12v and 5v than display board is very bad.If no voltage at all then main b. is bad or the noise filter fuse is bad.

All Whistler's that are not battery powered run on 12 volts with the center tip postive. You can order a power cord by calling 800-531-0004 or whistler's online store at www.whistlergroup.com.

That model is not battery powered. It requires a 12 volt power cord connected to your lighter socket to operate. You can purchase a power cord at any electronic parts store or from Whistler by calling 800-531-0004.

does the unit beep at all? Is the fuse ok in the units' power cord? Check these out. If the fuse is bad you can replace it with a 2 amp fuse from an auto parts store.

hi: first you will need open the monitor , them look for the power supplu board and with a multimeter measure the out put you shoud have 12v and 5v , if some of this voltage is missing your problem is the power supply board , you can try to fix it or buy a new board and remplace yours, now if you have the output voltage look for the power botton and take a measure in paralle with the switch you need to have there 5v if don't first check that the led is working fine because one i found the led bad and that was the problem , but that depend of the manufacturer construcction . if that led is fine your problem is a litter bit more complicate due that the problem will be on the logic board best solution buy a new logic board and remplace yours. best regards italocub

checked the lighter socket fuse? Does anything else run ok on the lighter socket?
