Question about Acer AL1715 (Black, Silver) 17" LCD Monitor

ACER AL1715ebm LCD MONITOR BAD VGA CABLE

I have an Acer AL1715ebm LCD monitor. The VGA cable went bad a few inches above the plug. It is not a removeable cable. I e-mail Acer with no assistance to the wiring color codes to put a new plug on the cable and can't figure out how to take it apart without breaking it. I can install a new cable on it and match the wire colors if I can get it apart. The cable would change colors unless you bent it and eventually the picture cuts out unless you hold the vga cable bent in half. I would appreciate any help. I would hate to trash a monitor that still works great because of an unreplaceable cable. Thanks in advance

    I've got the same problem.
    How do you remove the monitor cover? I can't reveal the vga cable.

You are in a bad spot, the plug is sealed when molded. maybe ebay has a defective monitor and you could take the cable off it.

Monitors will usually snap apart with a butter knife.

My Acer TCO03- power button is just blinking but no picture display


Blow hot air into the back with a hair dryer before trying to start it.

(not kidding)

if that works, one of the capacitors on the power board went bad.

even if that does NOT work, one of the capacitors on the power board went bad.

It is ALWAYS one of the capacitors on the power supply gone bad.

Being unplugged for a few weeks - as you stated - drained it of "juice", and it just cr*pped out. It was going to fail soon, in any event.

Fixing it can cost you less than a dollar, if you Google for information.

Best of luck!

Acer notbook black screen


Acer Aspire 5732Z series of Notebook PC?

Need to test whether the problem is;
A) Graphics chipset,
Or,
B) Video Cable,
Or,
C) Inside the Display Assembly

Inside the Display Assembly problem could be;
A) Screen Inverter
B) CCFL Backlight
C) LCD screen

1) CCFL Backlight:
CCFL stands for Cold Cathode Fluorescent Lamp. (Bulb)
Similar to Fluorescent lighting used in homes, and businesses; but on a MUCH smaller scale.

According to searches for an LCD screen, the Aspire 5732Z series of Notebook PC; uses one single CCFL for a Backlight.

One example,

https://www.laptopscreen.com/English/model/Acer/ASPIRE~5732Z/

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.

The CCFL contains MERCURY, just like it's larger 'cousins' used in homes, and businesses.

Mercury is a POISON. The bulb breaks EASILY.
If a CCFL is the problem, I STRONGLY recommend letting a professional change the CCFL out, OR just replace the LCD screen as a unit.
It contains the CCFL backlight,

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

View the last 8 photos.

Use a flashlight, and shine it at the LCD screen at various angles.
If you can make out graphics on the LCD screen, the Backlight is bad; or the screen Inverter.
90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.

2) Graphics chipset:
Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the back of the laptop.
The VGA port is on the Back of the laptop, and next to the Ethernet port.
[ Which is right next to the DC Power Jack (DC_IN), that you plug the AC adapter (Charger) into ]

This is an example of a VGA cable, and VGA connector (Port),

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

Scroll down for the VGA cable example. Note that color of connector does not matter. It is usually Blue in color, though.

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.

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.

No?
You have at least 3 display options available;
A) Internal monitor of laptop ONLY
B) Internal monitor of laptop AND external VGA monitor
C) External VGA monitor ONLY

Press, and hold the Fn key down.
(Bottom row of Keyboard, second key from left)
At the same time tap the F5 key once.
(The F5 key is the Display Toggle-Over key)
Still no?
Hold the Fn key down again, and tap once more on the F5 key.

No display on the external VGA monitor indicates a bad graphics chipset. More than likely the problem would actually be the mounting, of graphics chipset TO motherboard.
It is soldered directly to the motherboard using a BGA surface mount. (Ball Grid Array)

I doubt you have a graphics chipset problem, but this flowchart method entails that; and no 'stone should be left unturned'.

It would 'bite' if you tried diagnosing without checking the graphics chipset, and replaced video cable, screen Inverter, and LCD screen; only to find you needed repair on the graphics chipset mounting to motherboard; or replace motherboard.

3) Video Cable:
This is an example of the Video Cable. Acer deems it the LCD Cable, and that's what we will refer to it as also,

http://www.ebay.com/itm/Acer-Aspire-5732Z-LCD-Video-Cable-DC020000Y00-/360558336892?pt=US_Video_Cables_Adapters&hash=item53f2f39b7c

The long White connector at Top, plugs into the motherboard, in an area to the Top/Left of the Keyboard.
It then routes under the left Hinge, and up into the Display Assembly.

The smaller White connector below it plugs into the screen Inverter.
The LCD cable then connects to the back of the LCD screen, with the large connector shown to the Left side.

The small connector below it plugs into the Camera.

Just from normal repeated opening, and closing of the laptop; the LCD cable may become pinched.
This can cause pulling on it, and result in loose connections at motherboard side; and/or screen Inverter, and/or LCD screen side.

Could also cause damage to the LCD cable.
Stretched/Broken wires.
If the sheath of the LCD cable looks to be damaged, so may be the tiny wires inside the LCD cable.

http://www.insidemylaptop.com/disassemble-acer-aspire-5740-aspire-5340-laptop/

I will include a link to a free Service Manual, for the Aspire 5732Z series of Notebook PC. The above link, and other pictorial guides; are more for you to get a 'hands on' look, besides just looking at a Service Manual.

Here the repair is to Physically see, if you can plug those connections of the LCD cable, in tighter.
Visual inspection alone will NOT do.

http://www.insidemylaptop.com/replace-lcd-screen-acer-aspire-5733z-4851-laptop/

Tried to plug the connections in tighter, and does not cure problem?
Then the LCD cable is to be removed, and a continuity test performed on ALL wires in the LCD cable; with a multimeter set to OHM's. (1K)

Or perhaps take the LCD cable down to the nearest small computer shop, and have the resident tech check it for continuity.
Should only be a couple of bucks.

You MUST rule out the LCD cable before going on. Some may feel with the low cost of the cable, they may just replace it.
Parts changing I know, and not professional; but to each their own until you learn.

4) LCD cable checks out it's time for the screen Inverter.
The screen Inverter is a small circuit board, that converts the power, (Electricity) of the laptop; for the LCD screen, and CCFL backlight.

http://www.ebay.com/itm/New-LCD-Inverter-Board-Backlight-for-Acer-Aspire-5332-5532-5732Z-5732ZG-Series-/300612724754?pt=US_Laptop_Screens_LCD_Panels&hash=item45fdea2812

To test requires a sensitive multimeter. Read fairly expensive.

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

The plastic frame in front of the LCD screen is the Display Bezel.
Acer? LCD Bezel.
The screen Inverter is located behind the LCD Bezel, and mounted towards the bottom of the LCD screen.

Due to;
A) Non-accessibility of a sensitive multimeter
B) Ease of accessibility of replacing
C) Low cost

,many decide to just replace the screen Inverter.
Again parts changing, but IMHO is justified this time.

[No. You do not want to drag the partially disassembled laptop, down to the nearest computer shop.

A) No tech really wants to come in on someone else's repair, and pardon me; but really not after a non-tech.
Liability issues are also involved.

B) Judge JUST one hour of their service rate, compared to the price of a screen Inverter ]

5) Screen Inverter checks out? (Replaced)
Then the problem is the LCD screen.

Service Manual,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

Go to the paragraph that starts with Aspire 1200. (1200 in Blue)
Drop down to the 9th line. (5720 in Blue)
Scroll across, click on the blue - 5732Z

[Ignore if you are aware;
This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
(I would recommend upgrading to the newest version, though)

After you click on the file name (5732Z) it may take up to 30 seconds, before the first page comes up ]

Screen


Problem can be the problems with the graphics chipset, (Mounting issues due to overheating), video cable, screen Inverter, or LCD screen itself.

http://www.ebay.com/itm/Acer-Aspire-5241-5516-5517-5541-5541G-486736-001-Series-LCD-screen-Inverter-/261077449831?pt=LH_DefaultDomain_0&hash=item3cc96dbc67

Not advertising for the above website, nor seller. The above is used for reference, to show what the screen Inverter looks like

It's about 4 inches Long, (101.6mm), and 3/8ths of an Inch Wide.
(.375 inches, or approximately 9.52mm)

Primer:

An LCD screen cannot produce light by itself,

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

Click on - No Thanks, and the monitor icon.
(You may wish to turn your sound down first)

A Backlight is used to provide the light.
A Backlight can be a CCFL, or a series of LED's.
(Light Emitting Diode)

Looking at the LCD screens offered for the Acer Aspire 5517 series of Notebook PC's, there are two backlight types offered.
CCFL and LED.

(Aspire 5517 just designates a model series. The actual model number follows it. 5997, 5571, and 5535, are just some of the examples of a model number. It's on the bottom of the laptop)

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. About this thick -> aa
Average length is almost as long, as the LCD screen is in height.

A screen Inverter is used to convert the power from the laptop, for the LCD screen, and Backlight.

90 PERCENT OF THE TIME the fault is a bad screen Inverter.

HOWEVER, when LED backlighting first came out, they were using a screen Inverter. Technology changed, and a screen Inverter is no longer used for a backlight using LED's.

Fun stuff, huh? It really isn't an issue. If your laptop is using LED's for a Backlight, it will be proudly stated on the laptop. Usually on a sticker to the right, or left of the Touchpad.

Primer over.

Now we get technical;

Diagnose:

A) Laptop OFF, monitor OFF, attach a VGA monitor to the VGA connector on the laptop. Right rear side, blue in color.
General example of a VGA Cable, and VGA connector,

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

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

B) Turn the monitor on. If a CRT type allow it to warm up a few minutes.
Turn the laptop on.
By factory default, the display should show on the external VGA monitor.

IF not;

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

Hold the Fn key down, (Bottom of Keyboard, second key from left), and at the same time tap once on the F5 key.
(The F5 key is the Display Toggle-Over key)

Still no? Hold the Fn key down again, and tap once more on the F5 key.
Still no display? You have a graphics chipset problem. More on this at the end of the solution.

Display on external VGA monitor? You have a problem with the Video Cable, screen Inverter, or LCD screen.

C) Video Cable: (For Acer it is LCD Cable. I will still refer to it as the video cable)

The video cable attaches to the motherboard under the Switch Cover.
(Switch Cover is the plastic strip under the LCD screen, and above the Keyboard.
LED indicator lights, and Power On switch are covered by it)

The video cable then goes under the left Hinge, and up into the LCD Module. (Acer name for Display Assembly)
From there it connects to the back of the LCD screen.
(Acer = LCD Panel)

Due to normal repeated opening, and closing of the laptop, the video cable may become pinched, and pulled on.
This can create a loose connection at the motherboard side, or LCD screen side.

IF the laptop uses a screen Inverter, the video cable also connects to it. Can be pulled loose from the screen Inverter too.
Here is an example of a video cable for an Acer Aspire 5517,

http://www.batterystyle.com/acer-aspire-5517-cable-p-514000.html

Click on the photo view to enlarge.
The bottom side is the side that connects to the motherboard. The connector is hidden from view by the rectangular plastic strip.

This strip is used to gently pull on, and disconnect the motherboard side of the video cable, from the motherboard.
The top side connects to the back of the LCD screen.

Where the top part of the cable meets the wider lower part, you can see a small looped cable. This cable plugs into the screen Inverter.

(Either this video cable can be used for a laptop with CCFL backlighting, or it may be that the screen Inverter part of the cable is not used, if the laptop has LED backlighting. This is why the model number is always used to get the correct part, not just the model series number.

LED backlighting is relatively new, and I haven't had a laptop come to my shop that needs repair for this. I also am not going to take my new Acer Aspire 5552-3691 apart to see, lol! If it ain't broke leave it alone)

The laptop needs to be partially disassembled, in order to access the motherboard side of the video cable. Battery, and Switch Cover.
The LCD Module needs to be removed, and split open to access the LCD Panel side of the video cable.

Visual summation will NOT do. You need to physically try to plug the cable in tighter. All it takes is the space of this -> a, for there to be a loose connection.
You can leave the LCD module laying down on the table, with the video cable attached, to see if that was the problem before reassembling.

IF you see any apparent damage to the sheath of the video cable, also suspect damage to the tiny wires inside. (Stretched/Broken)
Suggest take it to the nearest 'Mom and Pop' computer store, and ask them to perform a continuity check on the cable.
(Multimeter set to OHM, 1K, and check all wires)
Damaged = Replace.

D) Screen Inverter:
To test a screen Inverter you need a sensitive multimeter. Read fairly expensive,

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

If no sensitive multimeter is available usual course is to simply replace it, due to the low cost, and ease of access to replace.
Parts changing I know, but sometimes it's the only feasible alternative.

Replacing does not repair the problem, or the laptop does not use a screen Inverter? Then the next step is to replace the LCD screen.

Here is a link to a free Service Manual,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

Go to the subheading that begins with Aspire 1200. (1200 in blue)
Drop down to the subheading on the left in blue - 5330, and scroll across to 5517. Left-click on 5517.

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (5517) it may take up to 30 seconds, before the first page comes up.

Hi.

Sure you can with a standard VGA video cable.

Maybe you will have to change your screen resolution to get the best display layout.

We have a panasonic 32"inch lcd tv.we want to


hdmi Ports Qty 3 port(s) PC Interface VGA (HD-15) HDCP Compatible Yes

I read your tv has 3 hdmi ports and a PC input.

if your pc has hdmi out - the you use a hdmi cable from the pc to the tv on one of the hdmi inputs.

if your pc has a 15pin vga cable you can unplug from your PC monitor (or go buy a VGA cable if you want to keep one on the tv and one on your pc monitor - or if you are using a laptop).

when you unplug the computer from the monitor .. check the pins - should look to be about 15 pins in the connector. it that will plug into the tv- then you are using a vga cable. if it will not plug into the tv pc input .. don't force it. It could be a dvi connector . .take the cable off the PC and to radio shack and they can fix you up (you need a dvi to vga cable - not likely, but possible)

I always turn off a pc before disconnecting monitors - and plug into the other display before turning the pc back on.

Good luck.
Bill.

Acer 5515 on external monitor


Get an VGA cable and connect your external monitor to your laptop via a VGA port that is usually used for digital projectors. In this VGA port, you can initiate dual monitors.

Then look at your keyboard and look an icon in your function keys (F1 to F12) that looks like a pair of an LCD and a TV like this {LCD icon/ TV icon}. In most laptop keyboards, this is located in F4.

When found, and with the external monitor hooked to the laptop via VGA port using a VGA cable, press and hold down the FN key and press the function key where the icons described above is located. Example, FN + F4 to toggle a single and a dual monitor.

Give it a try.

Pinkish back ground can be the sign of the lamps are going bad, but usually it will also cause the screen to go into shutdown mode also. Try New VGA cable or move the VGA connectors? Does the same on other PC?

Along with using another monitor to change resolutions, try changing Refresh Rate (in advance button), then hooking the LCD back up. LCD's typically like 60Hz Refresh Rate best, but try several.
