This is a protection circuit that prevents the tv from coming on (to stop damage of the components) ....you need to check your voltages off the power supply and make sure they all read well (EX: 24v12v5v etc). Also look for popped capacitors that would make the values lower than need be for the tv to power on properly.
Once you repair the power supply then you may need to replace other components if needed (EX: backlight inverter)! The backlight inverter is what lites the screen for viewing!
I would recommend to repair immedately and stop trying to turn it on over and over...this will futher damage your tv and cost more to repair in the long-term.
Please rate if this helps! :D

My suggestion is that you get an estimat from a dealer on repair costs and you decide whether you want to spen money on a part or new set. This is a bad circuit board and probably the power supply. The repair will be around $200.00 minimum unless you get lucky and there is no major issues and the board can be repaired.
The service manual says. you have what you call a "shut down circut" it is for safety and when one of the internal boards gets shorted or is not working properly, service doc reads as follows
7 Blinks SOS: Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times
thiera blinking 7 times is cuase by a fualt in sc,su,sd board.
If the board shorted another before it went dead you could have other issues, thats why you need a tech to look at it and give you an estimate. You never know, this being so close to warranty they might work with you on it.
