Could you get a replacement green light bub? Because ours does not work. Or do you have to get a new t.v. ?

the green light is power indicator not mic level. the green light should come on when powered up. remove mike cable and the see if green light comes on, If it does power down and connect mike and cable (hopefully you have a good quality one and not a toy)
Call Behringercustomer service. Where did you buy it from, if new it is under warranty and need to replaced with another new one. It is not an audio mixer the yellow and right lights are for clipping.

make and model of car?

check fuses. replace the blown ones and get back to me. good luck!

Look like the light in side stay on , you will try take the bub light out and see if it working fine you need replace new door switch . Let me know how it work i will tell you Next step for saving to fix the door switch

You should be able to access 3rd brake light through trunk.

yellow blinking or not? if blinking your lamp cover is open that could be you forgot to reconnect the wires back to the lead that monitors the lamp. It's a 2 wire molex connector either black or white that will be laying next to that light cover you removed to get to the bub. this connection may be labeled "CD". iF SOLID it is a high temperature indicator, the set would have to have a lamp that works for this, so I'm guessing the lamp hasn't turned on yet. the fast blinking green is your set initializing, testing circuits and fans and yup lamp cover switches.

check your brake light switch under the dash. The little plunger is probably stuck in the switch. Or the switch may need to be replaced.

i believe if you are a bit of a hands on type of person you should be able to do this yourself.
but not without researching !

read this page, should tell you everything you need to know, from the perspective of someone who had to do the same changing of the CMOS battery.

DISCLAIMER : I take no responsibility for any damage you may cause to your Axim. The parts and proecedures described in this guide refelct my own experience with my own Backup Battery (BuB) in my girlfriend's Axim X3. Your mileage, parts, anbd experience may vary.

Tools needed for successful BuB replacement:
1. fine tip jeweler's screwdrivers (helpful if you slightly magnetize the tip)
2. Varta V20HR rechargeable NiMH battery
3. electrically conductive silver epoxy
4. strong needlenose pliers
5. electrical tape or heatshrink (razor blade or scissors to cut to shape)

But here it is step-by-step:

1. Pop little rubber caps from 4 corners of back covers. Disassemble Axim X3 with small jeweler's phillips head screqwdriver. Be sure to plave all parts in a plastic bag or other container (4 scres rear cover, 2 screws near port). Disconnect the ribbon connector towards the bottom of the PCB and the speaker wire (also on the lower portion of the PCB). Backup battery should be the green covered circular item under the pcb).

2. Locate backup battery, Cut away BuB cover, & CAREFULLY use strong needlenose pliers to grip and "roll" the leads off of BuB.Be very careful with the leads.

3. Mix dime sized batch of silver conductive epoxy (do NOT hot solder this battery, heat will lead to BuB damage and destroy lead connection to wire).

4. Apply epoxy to both sides (not too much)and afix respective leads to respective side (red lead goes to +, black lead goes to -). Secure connections with some type of clamp (I used a binder style paper clip, but a wooden close pin or something else that will hold the leads to the BuB while the epoxy cures (Mine took 24 hours to cure).

5. Recover new BuB with protective covering (I use electrical tape cut to the shape of the BuB. Covering WILL have to be form fitting to fit back into Axim BuB "slot".

6. Reassemble and charge Axim and charge.

I generally fix this by re-seating the bulb housing. Take it out and put it back in. Look for cracking at the base of the bulb on the mirrored surface. It could be a barely functioning bulb that isn't busted, but can't initialize. I would take it to a shop that has the same bub type in a housing and make a quick switch.
