I have a Hitachi Plasma model #P50S601 that was working fine and then lost the picture with the power light, which is typically a solid blue when on, turning to a flashing blue. I take the power cord out and then turn it back on and it appears that the picture attempts to return for a split second but then reverts to a black screen with the light returning to a flashing blue. I read somewhere else on here that this could perhaps be a board issue. Would anyone have any suggestions or recommendations? Any help would be greatly appreciated.
