    I have exactly the same issue and Samsung are quoting £300 to fix it, half the price of the TV.

sounds like a power supply7 problem such as a power regulator is bad or maybe the Horizonbtal deflection cu8rcuity is defective. sounds like something if you ask me? should be taken care of by the pros??? Im sorry not being able to assist you better but these sets have hundreds of volts nin them and shoulnt be played with by an unauthoized service company.. Good Luck

Most likely the issue in on the large signal board. The TV is going in to shutdown. Repair might run $200.00 or so.

SOURCE: tv wont turn on the timer/standby light lickers

Open up the tv. On the boards that have connectors, de-attach all of them, one by one. Use a can of "duster" to clean out each receptical, then re-attach each piece. Do this to each and every connector on the boards inside. This should solve the problem.

Hi iv pulged my pc in to my samsung ps42q97hd and well i start the pc up and its fine but when it goes to the login in bit the picture starts to go on then off and flickers all the time need help asap...


Check the video resolution.
firstly boot in the lowest resolution possible, then go one by one increaseing the resolution till you get the max possible without flickering.
My guess is that the pc video reloution is to high and/or wrong frecuency.
