Display not illuminated......need help
1999 LS400
The area highligthed in red does not illuminate when I turn the lights on. I'm assuming the bulb is burnt out.
Can someone please let me know how to take it apart to change the light bulb? and what kind? Thank you.

yeah it's just the backlighting that is burned out. there are a set of #74 bulbs behind there to illuminate the panel. you will need to remove the vents to access them and have them replaced. you mean the WHOLE panel is dark? i ask bc usually only one bulb goes out leaving one side still lit.

Things are all written in Japanese and it's Celsior's but just viewing photos below might gives you a good idea to remove the display unit. The site owner below is explaining how to replace the CD changer but upper half of the page is effective for your purpose. Just click the small photo to view it bigger.

I think I'd better add some.
>Can u pls tell me how to remove the vents?
Prior to remove the vents, you' better to remove the wood panel at the shift **** first to access the display from the bottom side.
The vents are supported just by two hooks indicated by yellow arrows. To release those hooks, the left side should be pushed to the direction left and the right side to the right. This was not very easy for me to do for the first time since I didn't know how much I should push but I succeeded it. You must push rather hard but don't break it.
After removing the vents, you remove the display in accordance with the photos.
The site owner named "jt" runs a site called Celsiorup.com. Pages are all written in Japanese but there are many useful photos and you can understand the contents just viewing them. He is kind enough to introduce what he himself has done as well as other Celsior owners have done. I owe him a lot.

I just need to find that plastic pry bar he is using so I dont damage the panels. I have pry bars but they are all metal. Anybody has a recommendation as to what the right tool is to use for this job?
Can someone tell me if the light bulb is a lexus only part or can I buy it from a local parts store? Anybody has the part number ?
I need to know before I tear into this and have the bulb ready.

the bulb is not a lexus only part. you should be able to get it at any auto parts store. #74 but i am not sure on quantity.
edit: you may need to transfer over a green "condom" which is placed over the bulb to give that green color. it simply slips off, like a condom .
example!

So much easier than replacing the bulbs behind the LCD panels in my '97 - they don't just twist out, and you have to solder new ones back in. And that's why my Pioneer unit has no illumination properties whatsoever (except for a VERY faint green glow when the car is in park and the headlights are on).

well crap! this might be the same on his 99. i have a 97 as well but never had to replace these bulbs...yet. i apologize! this is not a first hand experience. as i stated i have a 97, and was assuming the panel bulbs are the same in the GS (in the pics i posted) in my entire post.

don't worry, you will get additional use from the pry tools when you manage to break the display on your $650 smartphone like I did, and have to replace it yourself to avoid buying another new phone!

I should had informed you this together with the procedure to remove the display unit. Regarding the bulbs they are soldered as below.

Most of forum members us "CelsiorUp" are replacing open bulbs to surface mount LEDs with current limiting devices such as resistors or small ICs that are designed for LEDs. I don't know the availability of those there in US but here in Japan a white flat LEDs sized 5mm x 5mm are available and we usually use them. One example can be found here below.

Most LEDs have a narrower emitting light angle compared with bulbs and you have to choose wider ones otherwise you would have a poor uniformity. Another item you need to pay attention is the polarity since LEDs are directional.
