    19" polaroid tla-01911c

    TV does not turn on. So I opened it and it looks like 2 of the caps are bad. But I was wondering if I should also replace the others? Also the one cap that is bad is a Procon 10v680 uf EY 8mm x 16mm. Can I replace this cap with the Rubycon 680uF 16v Ultra Low ESR Electrolytic Capacitor? The only reason I ask is because the voltage is different.

    bad cap info

    HEC 1500 uf 10v 10mm x 16mm
    Procon 10v680uf EY 8mm x 16mm

    Thanks,

    Yes, replace the others.

    Capacitors die from age, heat, and shoddy build quality. Capacitors DO NOT have to be visibly bloated in order to bad. They can be out of tolerance uF (a 1000uF measures 20uF) and/or have high ESR (ohm). A multimeter will be insufficient to test for ESR. For that you need an ESR tester which costs between $50 and $300.

    Most members here will recommend that you replace ALL capacitors with reputable brands from reputable sellers. Brands like Rubycon, Panasonic, and United Chemicon are suggested. A list of recommended caps can be found at

    The only reason I ask is because the voltage is different.
    Yes, you can go up in voltage.

      And, they can look physically good, still read properly on ESR, AND capacitance. like a good cap, as this test equipment use very low voltages

      BUT still be bad!! dont ask me how i know this. hehe.

      put a higher voltage, or a mega-ohm meter to them, they can leak DC current that your ordinary meters wont see... and be bad.

        Is it no harm to replace with capacitor without ripple current rating?
        by chth96
        When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


        Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
        But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
        Rubycon YK DataSheet (b...

        Opinions/Advice on Do/Should I replace ALL Electrolytic Capacitors on old equipment?
        by RetroComputingGrotto
        I've just been repairing some (very) old speakers with a loud hum that occurred as soon as you powered them on regardless if any actual audio is played through them. I work in a School so it's 99% likey that the Teachers have hardly ever turned the power off on them for well over 10+ years.



        As you can see the top large capacitor on the right has a bulge on the top so defincately needs replacing. As the one next to it is exactly the same capacity and voltage I planned to replace them both.


        What is your advice/opinion on whether or not on old(er)...

        Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
        by chth96
        I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
        Since then, This AC/DC adaptor have been out of order.
        But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
        After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
        Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
        And Is there any possibility that it will suddenly explode as well as to be out...

        Conformal coating on Samsung U32D970 monitor PSU, do I need to replace after repair?
        by psyduck
        I have a Samsung U32D970 monitor from 2015 I pulled out of the bad hardware pile that turned on and then turned itself back off after a few minutes of use and refused to turn back on. The PSU has part number BN44-00786A, and I found a couple posts about one that had blown with damage to the MOSFETs and PWM controller - but nothing about intermittent failures. I started a new thread and said that I would refresh the solder joints on the board to see if it was just a bad connection and possibly replace the PWM and PFC ICs. I then asked what my next course of action would be after those steps. I...

        G703GXR Dead CPU? shorted CPU power mofset replace, missing DRAMRST#
        by pc_okay
        Hello friends,

        I replace a shorted mofset (PU8104), now laptop is starting but no display, stopping at DRAMRST#.
        Resistance to ground on PL8104 is around 1-2 ohm, quite low but voltage seems ok 0.995V

        Any help would be appreciated it's a nice laptop !

        Thanks. 😃
