    About to recap Viewsonic VX2835 - Cap brand question

    Hi folks,
    I just ordered new capacitors to recap my viewsonic vx2835 (which has the same power board as the Hanns G HG28) and i was able to mainly order Panasonic FC brand caps for all but a few of the capacitors. However there were some caps i just couldn't find readily available here (czech republic) or in fact europe in a board recommended brand. I would have to order from the US or buy in great bulk.
    One example was the 22uF 35v and the 10uF 10v caps off of the power board.
    So i went for caps made by Yageo, Vishay (low esr) and Jianghai to fill the gaps.
    I haven't read much about these and wanted to know your opiniions as to whether they are any good? I also have access to Hitano caps pretty readily as well but know nothing about their reliability.
    Would you guys suggest i just reorder the odd caps from the US and put the repair on hold for the sake of the longevity of the monitor?

    Thanks again

    Some yageo and some vishay caps are not too bad how many are you talking about.
    A picture of the board and the position of the odd caps would help.
    Please also state the make and series of the caps you are replacing and the make and series of the proposed replacement. We can then see by checking datasheets (if available)if they are suitable - you could even do it yourself?

      If you are talking about 22uF, and 10uF, those caps will be absolutely fine.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
      For service manual, schematic, boardview (board view), datasheet, cad - use our search.

        Hi Guys,
        Sorry for the delay in getting back to this but here is some more info and pics.
        There is only 4 caps that i will likely replace where i cannot obtain Panasonic replacements. I have pointed out their positions on the board and they specifically are:
        Ltec: 3 X 22uF 35v TK series to be replaced by:
        https://www.conrad.cz/miniaturni-kon...2uf35v.k446245
        or
        https://www.conrad.cz/elektrolyticky...-rm2-5.k445643
        Then the 1uF 100v is a Taicon (M) 0739 to be replaced by:
        https://www.conrad.cz/elektrolyticky...rm2-5g.k445563
        or
        https://www.conrad.cz/radialni-konde...-100-v.k445943
        From my reading it looks like i would be replacing fairly low level no name brands with something the same or possibly a little better but i have no real world experience to go on with these caps whereas i feel you guys do and especially with this power board as it is also featured in the Hanns G which has many comments.
        So what do you guys think? Go with what i ordered or go the long haul and order from the US for more reliable caps to replace the above.

        Thanks again

          Few of us have experience of any of these caps but if you search the forums people have replaced Jianghai with Yageo but someone also says Yageo = Teapo (which are not great.
          SO based on Tom saying as they were small caps any would be fine and the fact that I have at least heard of Yageo with no really bad reports AND they are 105 degree (Temp) caps and one of the Jianghai is an 85 degree cap then I would go for the Yageo as best of a poor bunch.
          Not a shining endorsement but best I can suggest.

            Cheers for the reply selldoor.
            Just picked up the caps yesterday from the post office so will start the process in a couple of days.
            Have you ever heard or used Hitano caps before? If so any reports on their longevity/performance.

            Thanks

              If you type in Hitano into the search on the bar at the top it will give you the threads
              mentioning them - jury is out - middle of the road.
              see this post

                I see an Ltec unit in the photo - it should also be replaced anyway.
                My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

                  Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!

                  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."
                  ...

                  HannStar Hanns-G HC194d LCD monitor repair
                  by momaka
                  Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                  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...

                  GeForce 6800GT recap, need help identifying caps and finding replacements
                  by fl0w
                  Hi,

                  I just noticed that my Asus V9999GT (GeForce 6800 GT) had some swelling capacitors. I managed to identify the brown ones, which are Nippon Chemi-Con KZG series, 6.3V 820µF, which I plan to replace with this.
                  But for the yellow ones, I guess these are Fujitsu caps, without being able to identify which series... A picture of the video card is attached to the topic.

                  I need to replace:
                  • 2x 2.5V 1500µF => I plan to use this
                  • 2x 16V 330µF=> I plan to use this
                  • 1x 6.3V 680µF=> I plan to use this
                  Am I correct with the cap choices?

                  Thanks for...
