This morning I woke up, went to the tv and it didn't turn on. It's been a while that I have had it, but it just stopped working. The television turns on but the screen doesn't. There is no audio or video. The only functioning object is the light in the lower right corner, which is "stand-by". The light just keeps turning on and off. No progress for an hour.

Check carefully if there is no leaky diodes and/or capacitors in the power supply module. Check low - value resistors (0.1 and 0.47Ohm). These problem may cause the new IC to overheat and be destroyed within hours of operation. This is very common problem. Unit is dead and there are no blinks---Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open)

Sounds like it might be needing a new LOPT (Line OutPut Transformer). It produces the high voltage needed and if there are problems, it closes down most of the power supplies in the TV, giving symptoms just like you describe.
If you are lucky, it might just be a dry joint.
I'm sorry, but it is going to need to be professionally repaired, Probably $100-150.
Sorry it's not good news....
