    I believe its the power board, one of the transformer/inverter is burnt. i will replace it but the issue is how to reinstall the wire leads from the screen to their clips on the board. I would appreciate any ideas. thanks

Samsung tv #LN40B530P7F wont turn on,theres a little red light inlower right hand corner,so its gettin power,but it wont turn on


Are you using two remotes, the TV's and the cable box'? Is so, then you possibly may not have an understanding of how the cable box remote operates. Play around with it, or it could be something more serious with the TV, like the power switch button is defective.

40 samsung lcd tv problems


remove batteries from remote control and adjust volume to desired level. If the volume stays the same then there is a problem with the remote. If the volume lowers again then the problem is with the TV. the volume button on the TV or on the remote may be malfunctioning. Hopefully it will be on the remote. If it is the remote, take it apart and clean it with damp cloth. after allowing it to dry, re-assemble and try it out.

Samsung lcd LN40B530P7F 1.5 years old, try to turn on and only get red blinking light. Checked capacitors and none are blown. What else could be the problem?


How about the output voltages: standby 5v, PS-ON signal to turn on the 12v/24vdc power supply section? It may be in safety shutdown mode due to the detection of shorted circuits.
Bad cap can look normal but can have high ESR.
