    NEC lcd1970NX Lines ( bad nichion caps from 2004?)

    Picked up a 19 inch NEC. It has two inches of vertical lines that don't quite look right. You can see a video of it below that another guy posted.
    Mine does it as soon as it receives an image from the pc.

    http://www.youtube.com/watch?v=JlUtZ4_hYYU

    Tried VGA cable and got the "crazy" pixels.
    Switched to a HDMI cable on another pc and again "crazy" pixels.

    When the menu shows up saying there is no input it looks normal.
    There are nichion caps on the board that reads 2004 for mfg date. (j2060193 pcb-019 2004.10.07) and the power board.
    Read in the forums that some of nichions were not quite up to specs during that time.
    Did a close up visual inspection and none of the caps show any signs of bulging.

    Is it safe to assume the caps are from the "bad" nichion era and replacing
    them would fix the display?

      that's either a problem with the panel itself, or the LCD controller chip (i bet it's BGA..)

      the only nichicon series affected are HM and HN ..

          Would replacing the board fix the problem?

          I thought it was odd that when the "no signal" image popped up it was clean
          and when it got a signal then it would act up.

              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."
              ...

              Identifying caps on an old Zoom 9000
              by Paxman_Swede
              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...

              Gigabyte GA-6OXT :: caps question
              by Foetuss
              Good evening

              I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
              Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

              But I was also suprised about the bigger boys, which are 330µF 25V.
              Could it be they used 25V caps because they were cheaper / available at that time?...

              Replacement caps for Samson Resolv studio monitor 65A Amp board.
              by black6host
              Good day!

              I have a Samson Resolv studio monitor that has no sound output. I've opened it up and found two caps that are bulging on what I believe to be the power supply section of the amplifier board. The board is marked Resolv 65A AMP V1.2. The caps in question are YUSCON, 2200uF, 35V, 85C temp and have markings of RA(P) and are 16mm x 25.5mm tall. I've attached the schematic and the caps in question are C5 and C6. I'm assuming they are low esr caps. I've tested both caps and they test low uF, nowhere near 2200uF.

              I'm going to replace the caps and I'll be the first...
