Hi,

Do you see any LED being blinked or is it steady? Is there any sequence of blinking? If yes, kindly mention the same.

Thanks!!

    Thanks for your response!!

    The fact that the LED has a steady light and is not
    blinking,indicates that no error is apparently detected(which we know is
    not right since you do not have any picture and sound).
    This would lead us to two possible conclusion.
    1-The main board is defective,not being able to perform right(no self diagnose and no operation).
    This main board called BE2 board is part#A1212544A
    It is available at:
    http://www.partstore.com/Part/Sony/Sony/...
    It costs about-$360.Add another $140-$150 for labor and the repair will be around-$500.
    2-the
    main board is locked,by something else,keeping it from operation.This
    would be the Tcon board,that unfortunately is not available and the
    whole panel will need to be replaced,unless you will find it at some
    internet parts dealers,that sell scrap parts.


    Now if you can find this Ton board it will cost around-$120.Add another $100-$120 for labor and the repair will be around-$220.
    If no T con board can be found,then to replace the whole LCD panel will be totally uneconomical,the repair will be over-$1500.
    I hope this help you make a decision about this TV set.

    Let me know,if needed further assistance.

    Hope i helped you.

    Thanks for using ' Fixya ' and have a nice day!!

Tv tries to power up and then shuts off, again and again.


If the fuse were to be open then you would have no lights coming on at all. These days it is very unusual to have an open fuse. You will have to have a technician look at the TV.

DVD picture cuts in and out first 15 minutes


This is like the problem I had for some months. After a lot of exchanging cables and troubleshooting on forums like this, I decided to call in the Sony service engineers.

The problem turned out to be nothing more than a menu selection. You need to check the setup menu under video and select the colour system you are using (NTSC, PAL). The factory setting on the TVs is 'auto' apparently and sometimes a weaker signal will cause the auto colour setting to drop in and out. In our case we set it to PAL and the problem has not recurred.
