    Sony 32inches LCD TV turning off and on

    Hi,

    I am experiencing problem with my Sony 32 inches LCD TV which would turn off and then on suddenly. This would occur frequently when I first turn on the TV, then it would go away when the TV has been on for over an hour.

    Thanks in advance for any help.

    Best regards,
    Rickronn

      This looks like a thermal problem.
      If not under warranty, carefully try disconnecting and reconnecting the power supply board(s) first.
      There should not be any bulging capacitors on the power supply board(s).
      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

          I did try to open up the unit and clean up the dust to help air flow but it did not help.

          Also, it is strange that it switches off and on when it is turned on a while. Then it is gone after it has been powered up over an hour.

                              Hi all,

                              I have a Sony Bravia KD-60X6700E which has decided to stop working. To describe the symptoms - it just decided to stop powering on one morning. No standby LED, no sounds, no picture, no startup logo - nothing. Doesn't respond to the remote nor the physical power button on the unit.

                              I have tested the power cable for continuity. I have also tested the fuse, and that too, has continuity. However I haven't gotten much further with the probing. I've prodded the secondary side of the power supply where the connector connects to the main board, and there's no voltage...

                              Sony KDL-46HX850 Can't upgrade/update firmware
                              by dkneyle
                              Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.

                              Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about...
