Been asked to repair this , if possible, unlikely, but I will at least look. DLP type. Never looked in a projection TV before, currently red LED falshing , supposed to indicate blown bulb. No light at all on switch on . Prior to that , not seen by me , only reported, there was a slightly diagonal shadow across the very right hand edge of the screen, but still being used like that. Only 2 wires to the bulb , is it filament type ? if so open circuit, but no obvious blackening or anything. The whole inside is covered in dust, including a very dusty reflector on the bulb. Would it be safe to blow out the dust, from the whole iside of the casing, with a 1KW blower or is there anything like the rotating filters likely to be dislodged or damaged.?
