I have a purple flashing light next to the lamp on my viewsonic px747-4k. No picture will show then it turns off. Does this mean its time to change the lamp?

there is a colorwheel inside the dlp projector that spins and the light shines through the colored lenses on the wheel, onto a dmd board, and reflected out through the lens. however, if the wheel motor is bad and won't spin, the light won't even turn on. i recommend replacing the colorwheel
when you turn TV on, watch to see if the Lamp Fan is running,if it stops when Lamp trys to light then set will not come on.which then means Lamp Fan is defective.
Hi, Red light blinking 3 times shows problem with lamp cover. Lamp cover is not fixed securely in your tv after lamp replacement. Lamp cover is first thing that was removed to replace lamp, check lamp cover and make sure its back in place properly. Thanks.
Either lamp is failing (not covered under any warranty), or the ballast has failed. Or it may be a problem with the power supply, or even the fans... What is the picture next to the flashing light? If it's only the lamp light, then either lamp or ballast, if temp is flashing (the thermometer), it will be fans, temperature sensors, main board or power supply.
How many times Red Lamp flashes, its important as it shows problem and its location in tv. Below is detail of lamp blinks and you may know the problem area in tv by counting lamp flashes.
