    SE-CH530 system no standby

    Hi to all
    I have a SE-Ch530 system with tuner ,casette deck and cd player.
    Τhe problem is that it is constantly on standby I press the button of the amplifier or from the remote control of tuner ST-ch530 to become on the system but remains in standby mode .
    Has anyone encountered something similar?

      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 PN51F8500AFXZA broke off the tuner's F connector, can't get tuner de-soldered
      by DXseekerMO
      I can hear Fred Sanford now...."YOU BIG DUMMY".....I pulled the "F" connector out of the tuner by accident. The tuner number is BN40-00248B. Low and behold I had a scrap board with tuner number BN40-00248A. Although the tuner is different (according to Encompass.com) it's footprint on the board is exactly the same as the 248B so I decided to de-solder the tuner off the scrap board to see what I was getting in to.

      As you can see in the picture the terminals and solder pads are super small. No matter what I tried I could not get either the terminals or support...

      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...
