Hi guys im newbe and i have a Haire Model 42EP24S.

got some question about the set, first on the control board D1, D2 leds are off, do you guys know what these leds are for D1 & D2.

Currently the set will not turn on, and the power on leds flash red&blue.

Check power supply and all voltages are there, I Put my scope on test points

Any help would be great.
