Hello,

I have a 05 TL Navigation.
Some time ago, one of the light bulbs (I think it was Cancel button) went out.
So I bought a new one, opened the whole thing up, took the LCD Navigation unit out and replaced the light bulb.
I did not disconnect the battery, and when I screwed the light bulb in, there was a light smoke that came from the bulb socket. I knew it was not good.
Anyways, I tested the lights and they were working. So I put the whole thing back together and start heading home (I was at my brother's house). It was night time and I could see that lights around LCD screen were bleaker than the other lights (like on the cassette player). They kept getting dimmer until they all went out.
Yesterday, I got my order of 12 brand new light bulbs. I opened the whole thing up again, disconnected the battery this time, replaced every light bulb around the LCD screen and none of them work again.
Furthermore, light bulb on "Max" button (right next to dimmer switch), "Info", and "Select" buttons went out as soon as I finished putting everything back/.

Do you think I fried the board?
Any advice/recommendation will be welcome.

Thanks!

Did you use OEM bulbs?

whoa that's weird; any other lights out? +1 on the usage of OEM bulbs?
Have you checked your fuses?

hot_ice1027

Yes, I got them from the local Acura dealer and from Delray Acura the second time.

hot_ice1027

Yes, the fuses are OK. I checked both locations - inside and under the hood.

I have 08TL TypeS and the same thing happened to me... At first only my OFF & DUAL BACKLIGHTING were, then I had the body shop replace the bulbs. 3 Days later all the backlighting to the buttons that surround the NAV DISPLAY were out...

Any recommendation would really help!!!

I can't say why the smoke, but if you're gonna pull the whole thing apart because 1 or 2 bulbs blew out, buy and replace them all ... because if you just replace the burned out one(s), it's a matter of weeks before another one goes out. And you really don't want to go through all that labor again, right?

I agree DMZ. That is why I ordered brand new bulbs - 12 of them.
I did not understand why would the other ones go if replace some of the old burned out ones?
Also, could one bad bulb prevent other ones from working?

Thanks!

It has nothing to to do a burned out bulb taking another one with it. It has to do with the age of the vehicle and the probability that another bulb will die from age given the car is going on 7 years old.

I will take it apart again this Sunday and take it to my buddy.
He is good with electronics and he has multimeter. Hopefully, we will be able to get to the bottom of it.
Will keep you updated...

too lazy and too early right now to search forums for the DIY, but is there an easy way to take it apart to get to the lights? Mine has a few out and I am going to the dealer today to get screws for the center arm console(looked under the armrest and noticed 6 screws missing) so might as well get the bulbs also. Does anyone recall if our AT shifter lights up-the P,R, D,N. I dont believe mine has lit up in a long while?

there is no "easy" way to get to the nav screen bulbs.

take off silver garnish trim.
take off cup holders.
take off cubby holes area.
remove nav screen sourrounding.
lights are exposed.

yes the AT shifter lights are supposed to light up.

i would replace ALL of the light bulbs while you're back there so that you dont have to do it again for a long time.

tlmailman

When I take everything out for the navi, will the shifter lights be accessable also? And are those lights the same as the navi lights?

hot_ice1027

OK guys, sorry for the delay in my updates – working two jobs and going to school…
Anyways, I took my car to my friend and he could not do anything because he said that he needed the schematics of that LCD unit. I did not have it, the repair manual did not have it, so he ordered it from somewhere (I will post that info later if interested). So I will go to his place again and hopefully figure this thing out.
Meanwhile, my DVD unit crapped out. I sent it to Alpine and they fixed it. I put it back in yesterday.
While my DVD unit was out for repairs, I went to Acura to see if they can figure this out (damn the costs). Initially, they told me that it was OK to bring my car in for diagnostics without the DVD unit, but after screwing around with my car for half of the day, they told me that I had to have the DVD unit in for them to diagnose the problem with the lights. They did not charge me by the way.
If anyone is interested in how to get to those lights around LCD unit, I will be taking it apart this weekend and can make some pictures and post it.

I'm looking for a tutorial on how to do this… or more specifically what to buy! What kind of bulbs are in there? All of my lights around the nav are out.

MonkeyTrucker

Dunno about that, it could be similar to Christmas lights in that the bulbs are in essence a fuse, others will stay on with one or two burnt bulbs, putting stress on the other lights, resulting in their early demise afterwards too. Would seem plausible since they're on the same circuit.

Looking forward to your DIY type update OP, thanks in advance!!

mhrobson

Here's a link to where you can find the part numbers. I'm not sure if this is the best place to buy, but it is a place to buy and the prices look to be in the right range.

Hey guys that I have a similar problem I took my shifter apart to check if the bulb for the gear selector was burnt out and took it out to bring it to the store and when I put everything back in all my accessory lights including the ones on the steering wheel around navigation the dome lights pretty much all the lights on the little buttons have all gone out and also when I switch on my headlights the navigation does not going to night mode any suggestions?

did you unplug the battery first?

check out the fuses

polish_pat

I did not. I didnt think checking a bulb required that. All I did was unscrew knob, take out the plastic gear indicator, trim and the plate under that.

polish_pat

Correct me if i'm wrong, but I believe all lighting can be found under fuse 6, 7 and 32 all 7.5A. If so, they are all intact.

The dealership has had my car for the majority of the last 3 months trying to get random interior lights to work. They got them all to light up (except one) and as I drove off the lot they all started going out again, one by one. I brought my car home yesterday and some others are out now. It's not old bulbs. The new ones have gone out too. Navigation controls. temperature controls. turn signal, console lights, etc.

Fuzzy13

Did anyone ever figure out what causes the bulbs around the navigation to go out? I know it's something on the pcb board itself but what I don't know.

I've just replaced mine yesterday. I didn't disconnect the battery, but I did disconnect all the harnesses on the navi and the radio. I couldn't disconnect the antenna from the radio, but there are 2 screws on each side of the navi to disconnect it from the radio bracket, and also 1 big black screw on each side that points up as well. Honestly, I'm not sure how anyone could replace the bulbs without disconnecting the harness and removing the navi from the radio, unless you're seated in some sort of awkward position

fdesa

Reviving an old thread.....please tell us if your procedure worked. Are all the lights around the Navi still working today, assuming you still have your TL?

Rene Solis

I have the same problem. I am going to tapped into the center console light, Do you remember which cable do I need to tap into? Thanks in advance

chuck45

I am having issues with the navi Setup / Info Light which needs to be changed out. Does anyone have a link to a video or a video that can be uploaded to demonstrate how to replace the Setup / Info, Map / Guide, Menu button lightbulbs?

Much appreciated
