There are many problems that could cause the display to go out.

Yes , a fuse would be the most common but other problems can include a disconnected display wire , a bad ignition / battery cable or even just a blown unit all together.

Does the unit still produce any sound?

Do all of your dash lights work? Does it keep time and or radio stations in the memory? sometimes vehicles have a fuse that runs only that part of the radio if it is stock. The dimmer control could also be all the way down, if the dome light don't light bright, then that could be your problem, turn it the other way, it should be on the left side of the dash near the headlight control.
The problem is with the display power supply board getting too hot and cracking the poorly solder joints.
You have two options if it's not under warranty. One, you can try to
re-solder the joints. Two, you can replace the board. I tried to
re-solder the board with no luck. I had to replace the board. I will
include information at the bottom of this posting on where to buy the
board. It took me a long time to find someone who sold the parts.
Here are the instructions to re-solder the board.
To try to re-solder the board....
By opening up the radio you will find a narrow display power board
With in the left side of the radio (faceplate toward you). This board
has a metal cover soldered to it, with a toroid (wire wound doughnut)
inside on one side, and a bank of surface mount resistors and
capacitors on the bottom side. One end of the board (SCR heat sink) is screwed
to the heat sink at the back of the radio, the board is secured with 2
metal bend-tabs, and it has a white mini connector on the other end
which connects to the faceplate. Remove the board from the radio.
On the bottom of the board look for surface mount components
The colder these resistor/capacitor chipsets get, the brighter the display.
If you can't fix it with the re-solder posting, or don't
want to try it, you will need to replace the display power supply.
The board comes in a 3 board set, a new power
supply board and two new tuner type boards, sold as a "compound set".
The board is very easy to swap. Pull the radio out, take to 2 black
screws off the side of the face plate (1 on each side. Face the back
of the radio, now remove the screw in the top right corner. Pop the
front and top cover off the radio. Unplug the blue cable that leads
from the display to the display power supply. There are 2 tabs that
hold the power supply in. One is next to where the blue cable plugs
into the power supply. To find the other tab, look inside the half
circle on the tin heat shield. The board is painted white where the
tabs are. Now straighten the tabs with a screw driver. Pull straight
up on the tin heat shield. Now you have it out swap it with the new
one and put it all back together.
Hope you will be helpfull

Thanks for contacting

1998 Pontiac Montana Transport Radio and Temp Displays are out

don't know if you have had any luck yet.. the radio displays on those older gm cars do just simply fail , I have had 4 in that 96 to 99 time frame and each one just quit suddenly. I believe as crazy as it sounds that the display runs thru the radio. gm did this in all their newer cars in 2000 and up ..they use a data cable that runs thru the radio and feeds half the dash ..

You don't say which radio is in your Dodge Caravan but if you have the multi-speaker one find the fuse block module and check fuses 23, 6, 3, and 9. The 4-speaker radio does not use fuse 23.

My CD & radio just stopped working. The screen still displays everthing and the CD track changes just no sound.

This is usually an internal failure with the head unit (the radio box in the dash) usually getting a new head unit will solve the issue, however it could be as simple as a broken or disconnected connector. Try getting to the back of your radio and inspect the connectors. Also try jiggling the wires to see if its a loose/sloppy connection. Either way, you're going to have to pull apart the dash. In some rare cases, the vehicle will have an external amplifier, if this amp popped a fuse or had some internal fault, that would cause the radio to show everything, but have no sound. Check you fuses first, especially anything related to "Audio", "Instrument", "Dash", or "Amp"

My radio plays but the display do not work

This is an internal problem with the radio that must be addressed by a shop that specializes in these radios. This is a matter of an internal fuse in the radio. Ford radios do this all the time and the fix is relatively cheap and quick.

Radio, cigarette lighter, clock display went out on my '03 Toyota tundra. 20 amp radio fuse looks ok. Are there any other fuses I should check out? Thanks. TD

Under the hood there is some. Not sure about your application, but it might control interior stuff too. It will be a bigger amperage than normally inside the car though
