      What NEC model?

      What is wrong with the LCD to make you think the existing caps are bad?

      Something wrong with "." key?

          I don't think so unless I missed what you mean.
          KY is a Chemi-con series. [And therefor aren't NL series too.]
          Chemi-con caps have a shield logo.

              Sorry long day so far

              Its a NEC Accusync LCD 92VM Model L194F2

              Well i was told it wouldnt turn on so doing as i always do ignored what i was told and plugged it in screen came up no video signal as expected as no computer connected .
              So then connected laptop and it fired up showing bootup screens then promptly diplayed perfect picture

              This is where i started to scratch my head not because of a problem but i cant find a problem so opened up monitor checked all caps no bulgers
              No bad voltages everything measures out ok

              Couple of the caps look a bit darker than the others so just thought while i got it open maybe should just change the caps.

              Just think that maybe the guy hadnt checked his power lead for a blown fuse
              and just assumed the monitor had given up on him

                  Do the caps have a date code? Something like T0723 to indicate 2007 week 23?

                  If the caps are fairly new and the monitor is working, I would personally not change anything. I have been United Chemicon caps for the last few months and so far everything is good.

                  Others, however, might go ahead and recap.

                      PCBONEZ is right i mixed up front of the caps read shield mark ) KY 16V 1000uf.
                      The back reads : (M)105' 4(7) NL

                          I believe

                          (M) means +/- 20% tolerance
                          105 is 105C
                          4(7) might be 2004 month or week 7?

                          I'm sure PCBONEZ knows for sure.

                              Temp bit i ok with.

                              But if you are right about dates then maybe it is time to change them, though must admit they look good (i know that means nothing)

                              Had bought this to use the screen for an Acer i am repairing but as its working seems a shame to break it up ,this is the second unit i have bought this month for spares that appears to have nothing actually wrong with it.

                              Dont get me wrong i not complaining but now got to source another screen to finish the Acer

                                  4 - is 2004 - I'm sure about that part.
                                  (7) - I think is month 7 but not 100% sure.

                                  I know the year is right because it consistently matches the year in date codes on other brands of caps on the same boards.

                                  No idea what the NL is.

                                      Ok thanks for the input .
                                      I will run it on test for a few days and see if i can get it to stop working other than that as i said would seem a shame to rob it of parts when its working fine
                                      Thanks again

                                          Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                                          by momaka
                                          I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                                          For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                                          It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                                          Heathkit IO-4205 Power Supply Caps
                                          by eryjus
                                          Hello,

                                          First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                                          I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                                          I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                                          ...

                                          Been recently informed that NCC is EoL'ing many caps from ALL series, some series (like LE, long life, medium ESR/RC) will end as a whole.

                                          From what I've seen, D5, D6.3 and D8 caps are affected. So ALL the small caps, either standard or low-ESR, and many caps in filtering (in D8, especially FSP, but many others use that in output filters in SMPS).

                                          Last order accepted in 2024, so I will try to restock and pre-stock as many as possible to keep them caps flowing, but at the very last about 2030 I will most likely run out. Could only hope that other manufacturers won't...

                                          Hello!

                                          I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                                          The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                                          I have studied the board and...

                                          Help with switching power supply caps
                                          by captain150
                                          I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                                          I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...
