LN40C530F1FXZA LCD Plug-in:redlight in front is ON (stend-by mode). Press on/off on remote to turn TV on:red-light comes OFFand ON 5 times and stays OFF.Press again remote button:red-light comes ON and then OFF.I changed power supply board and it still doesn't come on. If anyone could help I would greatly appreciate it.
The main board would be susoect next if the power supply has already been replaced.
What if it's not blinking at all
I have a samsung 42inch LCD, When I turn it on, The red light at the front of the screen just keeps flashing on and off for a bout a hour.
is the telly on its way out ??
Samsung is known for putting to small capacitors in,had mine replaced 3 years ago,still working great.

You'll find some Samsung power supply boards here : http://www.usefulparts.com/index.php?main_page=index&manufacturers_id=11&sort=20a&filter_id=98&alpha_filter_id=0
but you have to open your TV first and find out model number
SOURCE: Tv doesnot power on
two options _bad backlight inverter or the main board ;eed to be change.
SOURCE: Panasonic 32 inch LCD TV will not turn on-red light flashing
The number of flashes is an error code. Count the number of flash. It looks like one of the boards in your set is failing intermittently. Panasonic codes for a guide as a starting point. Exact board STILL has to be verified;
One Blink: One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in the field. Therefore a replacement is required.
Three Blinks: Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Five, Seven, or Eight Blinks: The A board is responsible for five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.
Four or Six Blinks: The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board. The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.
Nine Blinks: Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.
Ten Blinks: Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of the power LED requires the replacement of the A board.
