Fax says it is off hook, what should I do?


The fax machine can't detect a dial tone (from a POST line). Since the Pixma MX420 doesn't have a handset, you may need another telephone to check your line. First, make sure that the telephone cord to the wall jack is connected to the RJ-11 port marked L. This is the lower of the two ports on the all-in-one printer. If the cord is in the wrong spot, swap the connection. That could solve the issue. If you have a telephone plugged into the upper RJ-11 port, check if you hear a dial tone. (Connect your test phone here if you haven't had one connected and check for the dial tone.)

Next, unplug the RJ-11 line cord and plug it directly into your test phone. Do you hear a dial tone? If you do not hear a dial tone, try a different RJ-11 cable. If the problem is solved, connect this cord to the lower port on the MX420 and see if the fax continues to give the "offline" message. If you still have no dial tone, take your test phone to another jack and try again. Find your incoming phone service box and check if that has a RJ-11 jack. If it does, you can test for a dial tone there. If the box doesn't have a RJ-11 port, you can have your telephone provider check the service.

If there is no dial tone at the service box, then your telephone company will fix the external problem for free. (With copper telephone service, sometimes rodents damage the wires. The provider has to fix this.) If you had a dial tone at the service box or another jack, then you have an internal wiring problem. This could be at the jack or inside a wall. If you take off the outlet cover, you'll find the wiring for the jack. This will either have screws holding down the stripped ends of the conductor wires or a punch-down keystone (with un-stripped wires). For the jack with the screw terminals, determine if any wire is loose/broken and strip a new section of wire. Then re-secure the wire under the correct screw. See http://www.lanshack.com/wire_phone_jack.aspx for a diagram. For the punch-down keystone, you'll need a special tool to reconnect the conductor wire. This tool is available at most hardware stores in the electrical wiring section.

If the problem isn't at a jack, you'll have to try to find the broken wire and replace the wire. Your telephone company's service technician will fix the problem for a fee.

If you have an internet connection with a DSL filter, you should check if the filter is damaged. This can lead to the above problems. If you have switched to a VOIP service, you'll need to make sure that it is compatible with the POST connection for the fax machine.

I hope this helps.

Akg c4000b hum


usually humming is caused by defective cables. Check if the cable is wired correctly. Open both XLR plugs and check:
Pin 1 shield
Pin 2 hot (usually red wire)
Pin 3 cold (black, blue or whatever)
Pinnumbers are written near pins usually.
If that doesn't help shake the cable for contact issues.
The microphone could have a broken shield connections as well. Maybe there's a small screw near the XLR output connector. Unscrew (sometimes this screw needs to be turned CLOCKWISE) and check connections.

Fix my broken acer aspire 9805wkhi display


Horizontal lines going down the screen, generally indicate a problem with the Video Cable, or screen Inverter.

The Acer Aspire uses a screen Inverter, because the Backlight is a CCFL. (One)

Primer before I go on;
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 two of them), or a series of LED's.
(Light Emitting Diode)

As stated previously; the Aspire 9805wkhi Notebook PC, uses a single CCFL for a Backlight.

http://www.screentekinc.com/Acer_Aspire_9800_Series_9805WKHi--20.1-inch--1680x1050-wsxgaplus-laptop-lcd-screen.shtml

http://www.laptop-power.co.uk/laptop-screens/acer/aspire/series-9800/model-9805wkhi.html

http://www.screenaid.com/acer-aspire-9805wkhi-laptop-lcd-screen-17-wxga-glossy-ccfl-backlight-p-8646.html

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height.

Basic example of a CCFL,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

View the last 8 photos.

A screen Inverter is used to convert the power (Electricity), from the laptop; for the LCD screen, and Backlight.
Note* Laptops that use a series of LED's for a Backlight, do not use a screen Inverter.

Primer over.
A) An external display device, such as a VGA monitor for example; should be connected to the laptop ->First; to make sure the graphics chipset is OK.

I believe it is OK, but this is a diagnostic flowchart, and the graphics chipset HAS to be eliminated as the problem; Before going on.

Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.

The VGA port is right in the middle, on the back of the laptop. Here is an example of a VGA port,

http://en.wikipedia.org/wiki/VGA_Connector

(Scroll down for example of VGA Cable)
You can use a CRT type of monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

With this laptop you can also plug a DVI connector, from a flat LCD screen monitor (Usual connector for digital flat screen), and use it instead. It's the white(?) port right next to the VGA port. (Closer to Left side, than VGA port)
Example of a DVI port, and DVI cable,

http://en.wikipedia.org/wiki/Digital_Visual_Interface

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

There are at least 3 display options;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external display device
3) External display device ONLY

Press the Fn key, hold it down; and tap once on the F5 key.
(The F5 key is the Display Toggle-Over key)
Still no graphics on external display device?
Hold the Fn key down again, and tap once more on the F5 key.

Good graphics on external monitor = Go on.
Bad graphics on external monitor = Problem with the mounting of the graphics chipset; to motherboard. Or bad graphics chipset. (Not very common)

B) Video Cable:
The Video Cable connects to the motherboard, up under the Keyboard. (And Top Cover's metal Static Shield) From there it routes up under the left Hinge, and up into the Display Assembly.

The main part of the Video Cable, then connects to the back of the LCD screen. There is also a separate cable coming from the Video Cable, that connects to one side of the screen Inverter.

The thin plastic 'frame' in front of the LCD screen, is the Display Bezel.
The screen Inverter is a small long circuit board; located behind the Display Bezel, and mounted down towards the bottom of the Screen Frame.
Basic example,

http://www.amazon.com/Inverter-Aspire-6930G-8920G-8930G/dp/B005GCD446

{The LCD screen is an assembly. It is composed of layers held in a specific pattern, by the Screen Frame. A thin metal 'picture frame', if you will.

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

Click on the monitor icon }

Due to just normal repeated opening, and closing of the laptop; the Video Cable can become pinched, then pulled on.
This can lead to a loose connection at the motherboard side; and/or back of LCD screen. (Also check screen Inverter connection)

Can also cause damage to the tiny wires inside the Video Cable.
(Stretched/Broken)
If there is obvious signs of damage to the sheath of the Video cable, there may be damage to the tiny wires inside.

To add; with age the insulation of the tiny wires inside the Video Cable, can deteriorate.
This can lead to exposed wires inside the sheath of the Video Cable, and lead to their touching each other.

It is best to perform a continuity check, with a multimeter set to OHM's. (1K)
Check each wire. Also have an assistant gently wiggle the Video Cable, as you check it. (Fluctuation of reading of multimeter, indicates a broken wire)
If you do not have access to a multimeter, perhaps take the cable down to the nearest small computer repair shop; and see if they will run a continuity test for you. (Few bucks)

The Video Cable's condition, and connections; HAVE to be checked before going on.
You MUST rule the Video Cable out as the problem.


Problem here is there is no Service Manual; nor guides in how to disassemble, that I have found; nor has one come into the shop.
(Made in what? 2006? Hmmm?)

Looking at the reviews of it, to see what it looks like; the laptop looks to be the type of model that the Keyboard is removed, then the Top Cover (Upper Case); THEN access to the motherboard side of the Video Cable, can be gained.

Fun stuff, huh?

ALL power is removed. Remove the AC adapter (Charger), and Battery.
Use a multi-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise DO NOT mix them up.

Basically follow what this gentleman is doing. Screw locations may not be the same for the inside area on the bottom; but will have screws that go around the perimeter of the Base Enclosure.
(Bottom Cover)

http://www.youtube.com/watch?v=6k-FnZze3c0

Also on yours, look down in the Battery Compartment for screws to remove, and when the DVD drive is removed, see if any screws are along the 'lip'. The outside edge of the laptop; where the outside edge of the DVD drive was.
(Going from bottom view towards the Top Cover, there may be screws in that 'lip')

Look along the compartment opening edges, too. (Along the lines of the one's he found )
Ram Memory compartment, etc.

The Keyboard has Tabs on the bottom edge. The edge that faces you, not LCD screen side.

http://www.amazon.com/Acer-Aspire-9805WKHI-Replacement-Keyboard/dp/B006T0V8VA

(Click on photo to enlarge)
When the Keyboard is removed, it is slightly tilted up on the LCD screen side; and then moved forward a little. (LCD screen side)
If you lift the Keyboard straight up, you may break the Keyboard tabs, and/or Top Cover.

The top of the Keyboard has Detents.
May be 3 to 4. (Maybe 5)
The Detents are small (Very) rectangular shaped, and right above the Keyboard. Once depressed with a flat tipped Jeweler's screwdriver, the Keyboard can be slightly lifted in that area. (LCD screen side)
Then go to the next one, and slightly lift the Keyboard, and so on.

The Keyboard Cable STAYS attached to the Keyboard. It has NO connector on the motherboard end. (No plug connector)
It is a Flat Flex Cable.

After all screws are removed, the Top Cover pops loose.
The Top Cover has Tabs, and the Base Enclosure (Bottom Cover), has matching Latches.

http://www.youtube.com/watch?v=3AxVE6__kEY

You have to PHYSICALLY check the motherboard connection side of the Video Cable, AND LCD screen side. Visual inspection will NOT do.

http://www.insidemylaptop.com/replace-screen-on-acer-aspire-5830tg-6782-laptop/

Look for screw covers going around the perimeter, of the Display Bezel. These are usually plastic, or synthetic rubber. I just gently pry up on one side of the cover, and then pry it up, and off.

The screw covers are attached with a type of rubber cement.
If carefully pried off, the screw cover, and it's glue may be reused.
[ Most of the time. I stick them (L-I-G-H-T-L-Y) to the Display Bezel, for safekeeping ]

Now remove the Philips head screws.
The Display Bezel is gently pried off, by flexing one side; and sliding your fingertips under it.
(On LCD screen side. I wear computer gloves. You may wish to cut a cereal box, or similar cardboard; to fit the inside edges of the Display Bezel; and protect the LCD screen from your fingernails )

Work along heading towards the Top, and around.
Once the Display Bezel has popped about halfway, or more off; the Display Bezel should come the rest of the way off all at once.

Remove the screws which hold the LCD screen to Display Cover.
Tilt the top of the LCD screen towards you; so you can access the Video Cable connection; to LCD screen.

Continuity check reveals the Video cable to be OK? Connections were tight?
Replace the screen Inverter.

Testing a screen Inverter = using a Sensitive multimeter.
Read fairly expensive,

http://www.fonerbooks.com/test.htm

Due to this; the low cost, and ease of access to replace; the screen Inverter is usually just replaced. Have to work with what you've got.

Screen Inverter replacement doesn't do the trick; replace the LCD screen.

For additional questions please post in a Comment.

It wont charge


it could be three issues. 1.) The battery is dead. 2.) The cable charger is a cut wire or is faulty 3.) The charging port on your phone is broken and not delivering power to the phone. If it is the battery or cable, you can purchase new ones from many online sites, such as Amazon. If the charging port on the phone is broken, you must call your cell phone provider and let them now. This way they can send you a replacement as soon as possible!

Only one wired connection works


have you tried the same cable in all 4 ports?
If it works in all the ports, plug the other cables in and reboot everything. PC,s modem and router.
You may be getting ip address conflict, rebooting should cure it.
If the same cable just works in 1 port, the router is broken

The part that you screw the cable wire into is broken off.


you don't need the connector that broke off. Do you have a cable box ? if so use the video output. That's the yellow, red and white leads. hook them to the video 1 in on your set. switch the set to video 1. If you don't have a cable box use a vcr or combo vcr dvd with a tunner.
