I have a Dell 1510X projector that has accumulated numerous white dots on the screen. It started with 3 dots in the upper right corner and has since spread, covering most of the right side of the screen and extending into the middle. I use the projector with my PS3 connecting via an HDMI cable. I'm sure the projector is out of warranty as it belonged to my roommate's brother who brought it to our house a couple years ago. I would still like to get it fixed. Any help would be greatly appreciated. Thank you.
Here’s what you can try.
Reset the projector to factory default settings:
If the issue persists, then try reseating the lamp.
Here’s how you can reseat the lamp:
If performing the above steps do not resolve the issue, then check if the Dell logo appears corrupted.
If you are able to see the dots on Dell logo, then adjust the brightness.
If the above steps do not work, then it could be an issue with the bulb or the projector. If replacing the bulb does not resolve the issue, then replace the projector.
Please reply if you have any questions.
