    Sanyo DP32746 capacitor help

    I am repairing a Sanyo DP32746 TV. However I am having some difficulty finding replacement capacitors.

    To give a brief synopsis of the problem, the TV will not turn on. There is not even a standby light when it is plugged into a known good outlet. Fuses are good. Power cord is in excellent shape with no shorts or opens detected. All solder joints are in good shape with no hairline fractures. I do not see any indication of burned or lifted traces. The one thing I did notice is one of the 200 volt caps is bulged at the top. The capacitor does NOT have a cover on top, plastic or otherwise. The top is scored with a "+" pattern for the vent and is metal.

    Also, please- I just want to find the replacement caps. There may or may not be another problem existing on the power supply board or even on another board altogether. The bottom line regardless of what the actual problem is is that I do not like caps with bulging metal tops.

    The original capacitors are Nichicon and are on the power supply board. The bulging capacitor is a 200 volt 820 uF GG series with a package dimension of 30mm dia. x 25mm tall. I would like to replace the 2 other capacitors, one being another 200 volt 820 uF and the 3rd being a 200 volt 470 uF with a package dimension of 25mm x 25mm series GN. They are all snap-in style capacitors that are then soldered onto the board.

    I am unable to locate either of the GG or GN series in the values I need. I found similar Nichicon capacitors with the right voltage and capacitance ratings and the same package dimensions but they are a different series. I was able to find the rated ripple on the Nichicon data sheet to make sure I am getting the same or higher but where I am stuck is trying to locate the ESR value on any of the Nichicon data sheets. Any help would be appreciated. Thanks.

    High voltage caps like these are usually general purpose so that's why you may not find ESR value mentioned in the data sheets. In such cases, just replace the original capacitors by capacitors that meet or exceed the ripple current rating value while keeping the voltage and the capacitance the same.

      Thanks for the reply. I'm one step closer to having this TV fixed. =)

        Capacitor detached from PCB – RTX 2070 Super Founders Edition

        Title:
        Capacitor detached from PCB – RTX 2070 Super Founders Edition

        Description:
        During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
        I did not notice it detaching, so I am unsure of its original location on the PCB.

        Procedure performed:
        - Removed backplate
        - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
        - Reapplied thermal compound
        - Reassembled card

        Observed behavior after reassembly:
        - GPU powers on and operates normally under...

        Capacitor Diarrhea - Nichicon PL Series
        by DrewPhillips
        Hello All, I have on the bench a couple of PSU's which have some failed Nichicon PL series caps. They didn't "puke" their guts through the top, but instead "diarrhea'ed" corrosive brown electrolyte through the bottom, down the legs and onto the board. On one cap, the electrolyte rotted the cap right off the board leaving 2 little stubs, and also corroded a trace on the foil side.

        The PSU's are Power-One MAP series and are ringing-choke topology. The semiconductors have date codes in 1993. The PSU's were used in a commercial application, fan-cooled. They had failed...

        capacitive capacitor paralle with 24 volt dc
        by Wolf1977
        hi to all
        in an inverter for motor
        on input output modul has power supply 24 volt dc is coming from a electrolytic capacitor of main power supply of inverter modul
        parallel has an capacitive smd capacitor that is shunt
        i want to ask
        first what is the play of this capacitor
        and what value and voltage do you think must i use for that

        New Super Capacitor 5v DC Battery Spot Welder with a 12 volt power supply
        by sam_sam_sam
        This is a new item at Battery Hookup that I bought I have always wanted to buy a good capacitor battery stud welder but they are to expensive for my budget that I want to spend on one this was surprisingly moderate price for what it can

        It came by FedEx today so I decided to try it out on some tabbing that my battery stud welder has a little issue making constantly welded with out having to redo some because it would not get hot enough to do it properly

        Well right out the box when the super capacitor charges up with the setting as follows does a very good job the first...

        12/24 volt compressor cooler box inverter capacitor failure
        by sam_sam_sam
        This is my son’s cooler for his semi truck for his drinks the other day it started short cycling ( running for a second or two then shutting down ) and restarting four or five times then going into an error power cycle the controller then it would do the same thing again

        Found a 47uf@63 volts double the ESR value of a new one
        The 220uf@16 volts same as a new but 220uf@35 volt replacement capacitor

        The main filtering capacitor was not replaced because I did not have that was not too tall

        Where the 220uf capacitor is some type of switching power...
