The LCD displays on my recent acquisition '97 C230 seem very dim (almost impossible to read after dark). My service tech says, "They all are like that." I was wondering if that were true.
If not, is there an accessible "bulb" that might be burnt out? If so, how do I get to it?
Thanks in advance for any insight.

Set the dimmer on highest position. Now check instrument panel for discoloration. Check if some parts are brighter than others. There are numerous small light bulbs in the rear and you should be able to notice if one of them is burned.
If it looks good then your cluster is probably just not bright enough for you. I'm not a big fan of the old Mercedes clusters either. I wish they all switched to the 2000 S-class clusters (similar to Lexus).

There is a bulb behind each LCD display that will dim as soon as you turn on the lights (depending on how the dimmer is set). IF your LCD displays are not visible at all or do not react on the lights being turned on/off, it is possible that you have a worn bulb.
Start with adjusting the dimmer to the absolute maximum of light.

W202 Dash Lighting

First, thank you all for the replies. I try never to undervalue information!

Since the LCD (only) displays appear "dim" all the way across, could there be a "problem" with the dimmer (or some connection at the switch)? I have the dimmer turned up to max, and the "other" lights respond.

And: how would I gain access to the bulbs or the dimmer (my guess is that it's part of the cluster)? Is the cluster easily removable?

I appreciate all this advice - sometimes it takes awhile to make friends with a "new" marque.

Gillybenztech.....

Now there is a forum name ya can really get behind, don't ya think? On the 202 cluster, there are bulbs that illuminate the gauges, and seperate bulbs that back-light the odometer, clock and outside temp. The bulbs are replaced by pulling the cluster out of the dash. There are "hook" tools that are sold to pull the cluster out, it's not too hard, although on the C-class I usually pull the steering wheel off, it is a little too tight of a fit to pull the cluster out otherwise.......Gilly(BMW K75S owner)

I agree

Unless you have the telescoping steering column it's pretty tight. I've done it before without removing the steering wheel, but you have to be extra careful.
From my experience with these bulbs if they are burned you should be able to see a difference between brightness of outside temp and odometer or trip. Actually, during the day you wouldn't even be able to read the portion that has the bad bulb. If I remember correctly there are only two bulbs for the LCD.
But like I said earlier there should be a noticeable difference in brightness.
Also, you can remove cluster by taking out speaker and pushing it out from behind. This is a little time consuming, but safer than hooks (especially if you've never used them before).

As the last two threads already mentioned: the dash cluster has to come out to replace the bulbs and the steering wheel is way to close to the dash cluster.
It is possible to get the dash cluster out without removing the steering wheel (watch out for the top of the rear steering wheel and the bottom of the dash cluster), but it is normally safer to remove the steering wheel.
Remove lower dash panel, remove the airbag, remove the steering wheel, and push out the dash cluster from behind. don't turn the ignition key as long as the airbag or the dash cluster is disconnected, it will end you up with an illuminated SRS light that has to be reset by the dealer (not a problem, but a fuss).
If you decide to exchange a bulb, you better change all the illumination bulbs. 4 bulbs for the illumination of the dash cluster (2 different type of bulbs) and three bulbs for the LCD displays (every LCD display has its own bulb).

greetingz,
