I'm having a problem with the Traveler trip computer in a 95 Lebaron Convertible I just bought. The VF display isn't lighting up. but I don't think the VF display itself is bad. What's odd is if I physically unplug the unit wait a minute or so and then plug it back in ( with the ign. sw. on ) the VF display will light normally for about 2 seconds and then go off. If I turn the key off and back on it will not light up again until I unplug it, wait a minute or two and then plug it back in. Then the same cycle will repeat, the VF display illuminates normally for a couple of seconds, but only once after it's plugged back in The display read out appears normal when it's lit with full brightness, all characters, etc.
I opened the unit up, cleaned the plug contact surfaces on the PCB and took a look around on the PCB and didn't see anything burned, discolored or out of place. There are about a half dozen small caps on the PCB and they appear OK. No swelling or leaking. There also is a small black disc component that looks like typical MOV one would see in a surge protector or power supply, just smaller in diameter. This looks OK too.
It's as if a cap or something charges up and locks out the display. The instrument lighting bulbs in it work fine as the backlighting for the buttons is as it should be. I assume that there's some form of power supply circuit to provide the power for the VF display itself. It appears that the stored memory / data information is correct as the display reads properly for those couple of seconds it stays lit.
Normally the display should light up as soon as the ign. is turned on. The VF display in the radio works properly and follows the instument dimmer as it should to include the full bright daytime mode with the instrument dimmer setting push past the detent at max. so I think all the right voltages, etc. are getting to the unit through the harness connector plug.
Is there a schematic or service notes ( Photofacts ? ) for these that's available or does anyone know if someone can repair these things ?
