yeah sir ultra is right and also check diodes in the power supply section of your unit ,. some of it just get shorted specially the schottky diodes in the secondary section of smps supplies,sometimes a short on some of this diodes causes the power to drop and shows only a blinking indicator lights..but be aware of how it is tested ,. its different on testing normal diodes,..hope it helps,....sir.. : apologies
