Ok i have this set for sometime now and suddenly there's problem with power. The red standby light is working, but when u press it to on the unit, its like the set is on low battery. If u press the power button again, the light comes back to red standby. If u don't press the button back again, then the red light starts flashing. Is there a problem with the power supply? Less power supplied to the main board? Faulty power supply? Theres no display either. Only the power red light works. I thought it was cold solder joints, i re soldered everything, still same. TO check the power supply voltages, i dont have the diagram either 
Can anyone help pleaseeee.....
