Bad news: this is a sign of your video card or LCD failing. To check out which is failing, connect a known-good monitor to your laptop. If the color changing and blinking occurs on the second monitor- it's the video card. If it doesn't: it's the LCD.

No picture on acer aspire 4720z


Try connecting it to a TV or monitor, if you get a picture on them the fault lies with the screen itself, if you still don't get any picture it may be a graphics/motherboard issue.

Need to have audio in my acer 4270z


I need more info, if I am right, your acer laptop model is Acer Aspire 4720z instead of 4270z. There are different audio drivers for different operating system, so please post back the name of the of the Operating System (with bit version i.e 32 bit or 64 bit) installed on your Laptop, otherwise I can't help you since we/I need to select the driver for the specific o.s.

If you wish or if you can give a try, follow this link (click here), open the link, click "Notebook" in the box provided, then in the next box follow up box, click "Aspire"then in the third box, scroll down and select "4720z", all the available drivers will be displayed on the next page, you'll need to select the operating system from that page.

If you need further help, let me know with more details.

Good luck.

Thanks for using FixYa.

The CPU Cooler does not seem to be doing its job properly. I would suggest you use a laptop Cooling Pad. It is a tray for your laptop and has a number of cooling fans to keep your laptop well circulated.
