    Temporary use of 6.3v cap for 5v standby line?

    Hi,

    I am not going to be able to get some proper caps for a faulty TV of mine (Samsung plasma) which has a failed standby cap (2200uF, 10V), for several days (I'm waiting on putting in a larger order with Farnell).

    I do have two types of caps of the correct capacity, but neither are ideal. One is an Aishi 2200uF/16V, but this is general purpose. The other is an OST 2200uF low-impedance, but it's only 6.3V. Neither are exactly brilliant quality but would only be in for a week or so.

    Of the two, which would be the preferred option as a stop gap?

    Either will work fine.

        6.3V is fine. Pick a brand, I'd go for the OST but that's only because it's a known brand (shit, but not the absolute worst).

          Thanks for the responses. I wasn't sure if the margin on the OST cap was sufficient, but as it got the nod here I've installed it and the TV is now fine. I'll be ordering some Panasonic FR of the correct rating next week, but I'm almost tempted to leave the OST in for the time being, being the lazy sod that i am :-)

            Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
            by tvguy12012012120
            This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

            Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

            Samsung UN50TU8000FXZC shows thin horizontal green line when warm
            by cubytus
            Hi to all,

            I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.

            I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.

            Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...

            Vizio D50u-D1 Dead Set No Standby
            by fharris1977
            Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.

            Samsung BN44-00259A standby question
            by Crystaleyes
            Hi all.

            I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
            SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.

            Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
            The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.

            Yamaha TSX 120 Standby Problem
            by psssst
            Hello forum. I've recently been given a Yamaha TSX 120 DAB radio and ipod dock. Its working well however when put on standby its using 6.3 watts. The manual states less than 1 watt on standby. I measured this with a plug in monitor which seems accurate with other items. In use it uses around 7.5 watts. Firstly has anyone who owns a similar radio also got a plug in monitor to check if this is normal with this unit? In the first half a second the monitor shows 0.3 watts which I suspect is what it should use but something is switching it to be almost fully powered. I've searched the manual for eco...
