The LED (power/standby) light flashes red/orange five times and I hear the TV's startup sound, but there is nothing on the screen. This repeats every few seconds.
I've seen people with other models keep suggesting the replacement of some capacitors, but I've looked at the power supply board and don't see any bulging capacitors.
Follow these steps to figure out what problem is.
When you turn on TV, look at the back and see if the back light on. If it is on, the power supply and inverter work fine. The suspection now is main board and T-con board (the small board on the middle-top of the panel)
To find the problem from the main board or not. Look at the power supply and measure Vs on - turn on the TV, this approx 5 vlt DC needs constant once you turn on the TV. If it is drop or unstable - main board problem - replace it.
If Vs on is good - disconnect the T-con cable from the power sup. If power sup stop clicking - T-con need replacing. Hope it help.

Thanks for the response.
I haven't had a chance to check voltages yet, but I don't see any back-lights (I thought I did once, but they didn't seem to light up every other time I've tried). Also, when the TV is attempting to power on, I can hear noise from the "T-con" board at the top.
