For capacitors, always go by what is on the board and note the orientation. Sometimes schematics or board can be wrong. The values are on the side of the capacitors. Match the polarization (polar capacitors have a stripe indicating the negative side), uF, greater or equal voltage, and ensure they are roughly the same height and width. CLD-99 is a little different with (according to SM): C101 100uF 6.3V C106 10uF 16V C201 220uF 6.3V I'd go ahead and order all of them as well as C14 on power supply board since all four together will be cheaper than the shipping.

I'd go ahead and order all of them as well as C14 on power supply board since all four together will be cheaper than the shipping. Thanks, for the values. Did I miss them in the SM? How did you find them, for future reference, and to not bother folks? [EDIT] I was able to find some of the values but not all of them. C102 & C105 are listed as CKPUYF223Z25 and the diagram only says 0.022 next to it where C101 right next to it is listed as 100/6.3 which makes a lot more sense. Maybe it is a 22uF 25V? Also, C104, listed in the parts list as CKPUYX472M16 has 4 700P next to it but that doesn't correlate to 10uF 16V that d770 stated. Looks like 47uF 16V? Ugh. Also, C14 on the SYPS board isn't listed anywhere but Signofzeta here says its a "little blue 331" which is only slightly helpful. When I search the part numbers online I get a PacParts hit but no stock and no description of the part or values. Looks like I'll have to take this thing apart to find all the correct values. Easy enough to find them and get replacements after I pull it apart but much faster to have the parts in hand when I open it up - Thank You. I have a local electronics store that I buy all my supplies from. It will likely cost me more in gas to drive 15 miles there and back than the parts themselves. Thank You both for all the help and advice. I'll grab parts soon and maybe do the work this week sometime and report back.

The rest are not electrolytic, and it would be very rare for them to fail. The capacitor part numbers at the end of these manuals are no longer of use. Ok cool that makes sense then, thanks. Yeah I found them but I had to really zoom in and look for them.

Thanks To test the Power Supply Board only is ok or not - that it is giving the correct Supply Voltages - ' DO NOT JUMPER BETWEEN POWER and GND ' Yes its a Jumper ( using a 1K resistor) between Pins 2 and 3 on CM22....this is the +V5 Ever and Power On points.. ...when you do this it will switch the boards power supply outputs and so then you can check their voltages. Make sure you have removed the two Ribbon cables and the Spindle Motor connections first from the Power Board. Please be very careful!!!! especially measuring Voltages - Mains Voltage is very close and present - it is very easy to cause a short with Test Meter prongs! if not at all sure advise take unit to a Electronics Repair Shop or phone a tech friend..and tell them what you are trying to check.

Alright, I have parts, the tray is out and the front panel is off! I've removed the FLKY and PONS PCBs and am ready to remove and solder in new parts. However, I'm a little confused about C104 and C105. They both look like little pink resistors with color codes just like resistors. Both are shorted or have no continuity on my DMM. Attachment:
C104C105.jpg [ 104.78 KiB | Viewed 1766 times ]
All other caps have a measurable resistance on the DMM and look fine (not bulging, leaking or burnt). I'm assuming my issues is C104 and C105 right? d770 says C104 is 10uF/16V but the CLD-99 SM says it is 4700 and the color code on it seems to match (Yellow, Violet, Red, Black, Silver). With that I get 4700uF 20% 900V but please correct me if that isn't it. C105 is a .022uF with a color code of Red Red Orange White or .022, is that right? The SM only mentions it as CKPUYF223Z25 (0.022) which looks like it might be 25V C102 is the same part number as C105 which I don't even see on the board. There is a jumper wire there where the SM says it would be (near C101). I don't see anything that looks like C105 over there. I can't move forward until I know what is going on with C104 and C105 since they seem to be different than previously discussed. The parts I have don't match and the parts I bought perhaps are not needed. Please advise, thanks guys!

d770 wrote: As C++ says
The only reason CLD-99 is mentioned in the thread is because it uses the same model Power supply board as the D770 -> VWR1200 Ok, thank you guys. Sorry for all the questions. You've really been helpful and I appreciate your expertise. I'm obviously learning a lot here. So I put in C101, C106, and C201 but no luck. Same symptom: Standby light is on but slowly fades out when the power button is pushed. I guess now I should be looking at C13 & C14 on the Power Supply? I'll wait to hear your thoughts. I went off topic there for a second, but now we're back on the VWR1200 board Thanks again...
