Hello, Does that light blink as soon as the power cord is plugged in, or only after the power button is pressed please?

Also, do the backlights on the screen (what lights the screen) turn on when it is plugged in, OR when the power button is pressed?

Press power, not back light

Okay, hang on, taking a look here.

ok
TV Technician: Aric, Technician replied 2 years ago

Okay, this set only has a power board, mainboard and t-con board. The T-con will not have any bearing on the screen not lighting up, but the mainboard will (since you already replaced the power board). The mainboard provides the turn on command to the set, and will allow it to power on once the power button sends that command to the mainboard. So if I understand correctly, you have the same EXACT symptoms after replacing the power board? If so, then you will want to replace your Mainboard to fix the issue.

TV Technician: Aric, Technician replied 2 years ago

The different versions of the Mainboard are all available from the link below. Make sure you check the part number of the board against the one in your set to make sure they match before ordering:

is there a way to test these boards before replacing
TV Technician: Aric, Technician replied 2 years ago

Do you have a mult-meter?

Ask Your Own TV Question
TV Technician: Aric, Technician replied 2 years ago

Then yes. You ground your black meter probe to the metal frame of the TV, set the meter to DC volts, and use your red probe to test the pins on the power supply board- after pressing power once on the TV. Connectors CNM802 and 803 have all of your voltage outputs on them (5, 13 and then the high voltages to the LEDs). If you only have 5 volts, and no other voltages when power is pressed- then you have a bad Mainboard.
