    Re: Teac audio receiver shutting off intermittently

    I tried to clean up that switch but not a lot of improvement. So I decided to remove the small reset pin from the tuner board connector so that nothing can reach that switch. At this point, it's a workaround and not a fix but who cares, system works fine. Only drawback is that I can't reset the system without removing the case. Thanks rievax_60 for your help, really appreciated!

      Did you try with the switch removed but everything else still connected?

        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....

        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.

        Denon AVR-X2000 mainboard caps bulging
        by re-atari
        I have been using a Denon AVR-X2000 receiver in my living room for several years now, works perfectly, am very pleased with it. Recently I acquired another one, advertised as defective with flashing red led a few seconds after switching on. Picked it up to try repair and use in hobby room. After switching on, the on/off indicator led indeed initially flashes green for about 2 seconds, during which the display is visible, and then starts flashing red (at 2Hz) with a switched off display.

        I'm afraid the service manual is too large to upload here (55Mb), it can be found at https:/...

        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...
