    Hello Taran 2005,

    As soon as I plug the power on, the relay at the back will click and the power (green) light on and stay on, then the relay at the back will click on/off for every 1 minute , after on/off for three time the OPC will blink one and the power light will blink three time and so on untill I have the power unplug.

    Thank-you

    Thanks for your response!!

    I had a discussion with other experts regarding this problem.Simply 90%of the time its powerboard or mainboard them flashing OPC and
    power lights are not accurate for which board is at fault.There is a complete technical bulletin that was issued.

    Now, to explore which would is at fault, lets take it one by one :-

    1. Power board - This seems to be a more probable cause. Clicking or relay noise is mostly due to defective power supply board. Few caps on it may be bulged/leaked/swelled and unable to transfer the current. As board is receiving the current and the caps are unable to complete transfer it, causing this. Moreover, this model has been in limelight for caps failure.

    2. Mainboard - If the power board is fine, then we need to check this. There are many board level component that needs to be taken care of on this board.

    There are reports of LCD panel being failed on this model.However, i would not proceed to any speculation without checking the main causes.

    Let me know,once done.

    Hope i helped you.

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

    Try a factory reset procedure :-

    - Unplug the TV and count to 10 slowly.
    - Hold down the power button on the TV (not the remote.)
    - Plug in the TV while holding power button.
    - Count to 10 and release the power button.
    - Turn it on and hope for the best.

    Let me know,so that we could proceed.

    Hope i helped you.

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

Sounds like a over heating issue, try unplugging the unit and leave it for an hour , before you reboot. make sure there is some kind of ventilation in place . Also double check your connections very important.

How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
