Report "Westinghouse flat panel monitor, model LCM-19W4. When I turn the computer on the green "power light" illuminates but the screen remains black for several seconds, then it flashes white for one second, then returns to black for a few seconds, then flashes white again for only one second and then returns to black again. It stays black until the amber "power light" illuminates several seconds later. If I turn the monitor off and restart it, it will go throught his cycle again. It is totally unusable as it is"
