    HP VS17X Monitor issues

    I was given an HP VS17X monitor that will not come on at all. The power light comes on, but the monitor will not and I could not see if the backlight was coming on briefly or not. I ulled it apart and found two bad caps that had bulging tops, one with an orange substance on the top.

    After reading a lot I found that ALL of the capacitors on this board are on your bad caps list. I have included a list of all caps with specs and some photos. Could someone kindly point me in the right direction as to where the best place would be to find suitable replacements? Thank you in advance for any assistance!!

    This appears to be a design which combines power supply, inverter, and controller onto a single card. Interesting.

    Ordinarily I would jump in and list suggested replacement parts, but you didn't include dimensions of the existing caps. Refer to the 'Frequently Asked Questions' subforum, and review the list under 'which caps should I buy'.

    This is an updated procedure for selecting caps.

    Go to www.digikey.com. Near the top right corner of the page is a box with Part Number / Keyword. Enter capacitor and click Go.

    Click on Aluminum.

    Under Series select the series of caps you believe are acceptable. I usually limit myself to Panasonic FC and FM, but don't hesitate to select more.

    Under Capacitance select the value you need.

    Under Voltage select the voltage

    Under Package/Case select Radial

    Place a check mark by In Stock, then click Apply Filters

    Now I just did this for 680 uF 10 V and got exactly 4 hits. Looking over the specs, I see Panasonic FC and FM in two case sizes. I also note that FM series is rated for a longer life, and costs less. So I click on the Stock Number for the proper case size. On this page I enter the Quantity and click on Add to Order.

    Alternatively I can copy the Digi-Key Part Number and Manufacturer Part Number to a list and someone else can use these to place an order.

    Then I repeat the process.

    I prefer Digi-Key because they have good prices, a good inventory, and offer a First Class Mail shipping option. This will get your order to you in two days for about $2.00 in shipping.

    Note that in some cases dimensions are critical. Make sure the parts you select are not too tall or to wide to fit!!

      PlainBill, You could have just copied and pasted that reply directly into my dumb post. As we are asking basically the same thing. Though I'm looking for Rubycon and Digi-Key does not carry them, brand is not set in stone... I'm flexible enough to try other good quality caps.

      After using Digi-Key's search filter I'm comfortable enough with the good info they give as to select something that should fit my needs.

      Thanks for the info and link.

        Working on a list, give me a bit. (In case you wanted help on a cap suggestion list.)

            I can't thank everyone enough for their help in getting this going, especially to PlainBill, & endevite for taking the time to put together that awesome replacement list!! Endevite, in answer to your one question about the dimensions of the x1 - Su'Scon 82uf 35v UK 105 degrees, the dimensions are 8x11. I hope that helps or confirms your replacement recommendation.
            Many thanks again for all of the help with this project!!

              Is there height clearance for 8x15? Chemi-con 8x15 KY 63v 82uf 665riiple 7k hr lifespan would be the better cap.

                Endevite,
                Sorry for the delay in getting back....sometimes life's situations trump our hobbies. Anyway, no, unfortunately they will be a little to large for the spot. Thanks though, and thanks again for all of the other help. The caps are all in....great quick shipping from Digi-Key and now I'm going to work!!

                    Re: HP VS17X Monitor issues

                    I received one these and changed out 3 bulging Capxon 1000uF 10V KF (P630) caps. The monitor was made in Aug 2006.

                    I noticed that the HP has a stored memory function. Some interesting facts.

                    Monitor has been on for 29,984 hours (or 3.4 years). So it looks like the previous owner never turned it off or just let it go to sleep mode.

                    Backlight hours is 9,354 hours. So he got about 13 or 14 months use before the Capxon caps died.

                    Now to be fair, the Capxon caps are situated right next to the output transistor which was mounted on a large heat sink. And in this design, the hot air from that transistor flows UP right into the Capxon as you can see in the OP's picture.
