Hi, my HLN437W just started flashing, it happens in about 10 or so minutes, it flashes more when a bright image is on screen. I've changed the bulb a 1 year or so back, but it was my color wheel was the problem, so i have 2 bulbs, I've tried both, but it still flashes, now it shuts off and the 3 lights in the front are flashing now. what can i do to fix this? I put in the color wheel in myself, so I'm not afraid to install anything myself.:confused:
