^^^^^^^^ What type of capacitor would be a better option than tantalum?
I've looked around, and found a thread that goes into a lot of detail about low ESR capacitors made by certain manufacturers - https://www.clublexus.com/forums/ls4...capacitor.html . The capacitors mentioned in the thread are used in the ECU, and I'm wondering if they are a good option for the boards in the dash display.

and listen to Yamae, he is an ECU engineer who works closely with Toyota in Japan!

The caps I chose were:
10UF 16V - Nichicon, PW Series (http://www.digikey.com/product-searc...ds=493-1767-ND)
10UF 50V - United Chemi-Con, KZE Series (http://www.digikey.com/product-searc...ds=565-1702-ND)
4.7UF 25V - Nichicon, PW Series (http://www.digikey.com/product-searc...ds=493-1808-ND)
Again, not sure if these are the best / right choices, but I hope so. Any thoughts?

Also, many thanks to you and Yamae for the excellent / informative ECU thread - I learned a great deal from it. Thanks for taking the time to list this information - extremely informative!!!

A big thanks to the thread creator - I just managed to perform this operation on my own instrument cluster.
For those who wonder - the polarity is given away by the existing caps - the black side is negative.

To rice4ever, thanks a ton for this right up i just inherited a 93 ls400 and of course none of the dash lights/ radio and hvac lights worked or the gas gauge. Picked my parts up from frys this evening got them in and sure enough its all fixed!! Much props!!

Sorry to bring back an old thread. I replaced the 3 capacitors. I basically went from nothing (no needle lights, warning lights, gas gauge) to full light on everything except the speedometer and RPM needle.
Anyone have an idea on what each capacitor controls? I'm wondering if its the needles themselves or if I screwed up one of the capacitors.
Also, I never noticed the problem before but my steering wheel adjust isn't responding very well. Is there a capacitor that controls this in the instrument cluster? Just wondering if I might've caused this problem from taking out the cluster and installing the 3 capacitors.
Thanks for your help. Great original post. It was my first time soldering so I wouldn't be surprised if I made some mistake along the way.
Any advice or guidance is much appreciated.

Type of Caps
Cowboy, Yamae,
I've already used the caps that was recommended by rice4ever, the ceramic type and fixed the problem. Do you think I should redo this job with low ESR caps picked by Dave or would it be OK to leave the caps in until something goes wrong?
BTW, the 3 caps on the dashboard fixed following problems on mine:
- Dashboard dark when cold.
- Gauges working sluggishly (the gas meter is the one that was most noticeable).
Replacing caps on ECU as LSCowboy recommended fixed following problem:
- Speedometer & tachometer gauge sometime doesn’t work (AKA Sticking needle)
I still have a speedometer needle being half lit problem. Know what to do to fix it but are not getting to it as partly, I may brake something else in the process, and partly I can live with that.

I think I would not worry about the instrument cluster caps as long as the cluster is performing as it should!
those caps are not as critical to use the exact type as the ECU caps

We have every gauge cluster part available for the LS400. We can also perform any repairs if you don't feel comfortable. Send us a PM with any questions.

My cluster does not lit up but everything works and it flickers. They also lit up when I turn on the headlight. Which capacitor do I remove to fix the lighting issue? Do I replace all the capacitor mentioned by OP? Your help is much needed. Thank you in advance.

I'm having the backlight cutting off issue... I do not see the C212, C142, or C147 in my circuit board. I think it's because I have a 1990 - 1992 model. Does anyone have the capacitor reference numbers for this model LS400?? Thanks!

Pictures Not Displaying
I am experiencing a similar issue with the pictures not displaying. I would really appreciate it if someone could re-post them or email me the original tutorial. Thanks in advance.

Ok I managed to get the pictures back, but i'm limited to 5 pictures per post so ill have to split the OT
REVISED*For people with some technical knowledge only* Do this at your own risk!*
Hi... My name is Rice. I wasn't gonna pay 1200 bux to get my 93 ls400 Lexus cluster to stop flickering and my gas gauge working again! Here is my permanent fix. It cost me $3 or $4 bucks!
Here is my cluster. I just took it out and I'am ready to get to work! The whole job took me 12-15 mins but I was a technician for like 15 years so please take your time!
Back of the cluster. take the white plastic cover off. It is held together with 10 or so screws!
I bought these capacitors from Frys electronics. If you don't have a Frys near you then hop your *** on www.Frys.com and order them by the part numbers provided below!
The labels with prices and part numbers
Unsolder (from the top side) capacitor from c212 that is located on the small board and replace with a 10 uf (10mfd) 16 volt capacitor.
