Question about Canon PIXMA MP160 All-In-One InkJet Printer

1 Answer

Audacity for the masses

I know I still have a bug in my Aspire 7720 but I'm gunna talk about that on another post.
Here's the issue now. I've been using Audacity (not Beta) for quite some time - to record some of my own tunes as well as songs from the internet.
From time to time I'm forced to purge it out and re-download it because it kaaks out on me. >One time won't engage the monitor tab; one time rit ecords a squelch for a second then cuts out. Here's my confession, I'm ditzing around with Live 7 (still am clueless) ... and I have routing all screwed up so that I get a quick antenuating feedback .
"OUCH MY EARS" I say!!!! and the sound won't work on my injput select to my Audacity program from that point on.
I think I could reset something if I only knew what that something was.
Happy New Year ... glad your here, and have your ear -can I buy u-wa beer?

Normal 0 Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

Screen has gone cloudy?

Kevin, Kevin, Kevin, should have posted your problem here first.

An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, or a series of LED lights.

In regards to the Acer Aspire 7720 series of Notebook PC's, the Backlight is a CCFL.

Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
(Approximately 2mm Wide, by close to the height of the LCD screen, Tall )

A screen Inverter is used to convert the power (Electricity) of the laptop, for the Backlight, and LCD screen.


The thin plastic frame in front of the LCD screen, (Resembles a picture frame), is the Display Bezel.

The screen Inverter is mounted towards the bottom of the LCD screen, and behind the Display Bezel.

This you already know. Posting for those who read this solution in the future.

How to install a audacity?

1. Go to In the middle of the page, there's a yellow box with download links inside.  I recommend downloading version 1.2.6 (the most current, non-beta version).  Unless, of course, you have Windows 7.  In that case, download 1.3.12 (the beta).
If you need help with Audacity, try the "Help" button on the top of the page.

I just wanted to figure out how to program my Keyboard for the Game Im Beta testing at this moment.

If the game is in Beta testing it will have several bugs. This is the whole reason for beta testing.

The only people that can give you a solution are the developers when you report the full status of the problem.

If you are unable or don't know how to report bugs in a programme you should avoid any beta test.

Most (if not all) new developments have Alpha (recognised developers/users and testers) releases.

Then a Beta will be released for general circulation for more extensive feedback from wider set of knowledgable users.

If you are posting here for a solution then you do not fit into any of the above categories and as such should not be involved it Beta testing.

Bottom line. If you don't know how, don't do it!

Hi, when iturnon my laptop (acer aspire 7720 17')

Its better to send the laptop to the manufacturer for a repair as we find it as a genuine issue with either the board or with the monitor. There could be no issue with the OS and looks like its a genuine hardware problem. Good Luck.

The Numeric keypad on my Acer Aspire 7720 doesn't work. When I press Num Lock key the indicator light doesn't come on. The main keyboard works fine. I am using Vista.

try to access command prompt outside of windows using the operating system disc. (by booting to cd and go to repair your computer options then select command prompt) if the keyboard works fine on command prompt, there's no issue with the hardware. but if it still doesnt work, you will need to replace the keyboard.
