    Help IDing some caps

    Hi all. I'm trying to replace some capacitors on my Onkyo TX-SR607 receiver's HDMI board. I count 4 different types. I think they are Nichicon. I'm trying to figure out what they are and what size they are, so I can order some replacements. I have my guesses, but I don't know what I'm doing!

    They are aluminum electrolytic capacitors, that is about the only thing I know for sure.

    E2 470A CD


    E2 220 4V


    E2 100 4V


    D3 220 4V


    My guess is 3 of them are 4-volt and 220/100 microfarads. No idea what the 470A would be. Any help would be greatly appreciated!

    You're right on the last 3. The first one is indeed nichicon, CD series 470uF 10V

      The last three are probably also Nichicon.
      I love putting bad caps and flat batteries in fire and watching them explode!!

      No wonder it doesn't work! You installed the jumper wires backwards

        Thanks! Is there any way to know the dimensions via identification, or should I just bust out the calipers?

          A basic ruler should be enough. The distances between those pads are relatively standardized.
          You could also use through hole capacitors and just bend the leads a bit so you could solder them on the pads. It will look ugly but it would work.

          Why are you trying to replace them in the first place? Do you know they're bad or it's just preventive?

            My HDMI ports are all not working and because of the heat inside the chassis, the most likely culprit are the capacitors on that board. I figure I'll just replace them all and if it starts to work again, great. If not, at least I tried!

              Errr, hmm, it seems on TVs that most HDMI problems are from the actual HDMI interface IC going bad. Not sure if it is the same in this case.

              Have you checked the output voltages of the voltage regulators on that board?
