How to detach the screen from the base.

check the cable for the bad monitor at BOTH ends. Some cables detach from BOTH ends, and if one side is lose, then you will get weird stuff happening....odd colors, lines etc.

Otherwise...it would seem to be a bad cable....which would **** if it is one of those that does NOT detach from both ends.....since you can't just go get another monitor cable.

Hello
Your TVs focus voltage has some trouble. You gets an out of focus piture now. There may be two reasons for this fault. The first one is, the focus pack trouble. The second one is picture tube base socket trouble. Both are repairable.
Focus pack is integrated with Line Output Transformer [LOT], and picture tube base socket is soldered directly to picture tube base card. You just open the TV and check whether there is any "Shhhh" sound comes from the neck side of the picture tube while tv is working. If it is so, you will get a smell of Ozone gas also. If it is so, switch off the set and unplug it from mains socket, pull out picture tube base card from the picture tube neck. Be gentle, and not make any shakes while pulling it out. The neck part of the picture tube is very thin relative to its other portions of the picture tube, and have a chance to break. So be carefull when you pull it out. You can see the base socket soldered directly to it. There will be two wires also, for some sets only one, attached to it. Normally the red wire going to a slot in the socket is focus wire, through which focus voltage reaches to the relative pin of the picture tube. Just detach the wire out from the socket, desolder it out and go for a similar type, and pin confuguration. Replacing it will solve your problem. After replacing the picture tube socket, a slight focus adjustment may be needed. Sometimes may not. The focus voltage can be adjusted. Its adjustment control is located on the above said [LOT]. There will be two adjustment controls, marked Focus and Screen. Out of which the upper one is for focus adjustment, and the lower one is for screen adjustment as its markings states. You just adjust the focus control very little, while watching the picture on your tv screen. Take menu display for reference, rather than moving pictures for focus adjustment, so that you will get a stationary image for reference.
The second stated trouble is related to the screen-focus pack integrated with the [LOT] itself. If it has got damaged, there is no other way than replacing the [LOT]. If so desolder it out from the circuit board, after detaching the anode cap from the top of the picture tube,and focus and screen wires. Before detaching the anode cap, care must be taken, as there may be some extra high tension voltage charge on the final anode of the picture tube, which is dangerous. You must discharge it before unpluging it, otherwise you may get electric shock from it, even after the Tv is switched off and unpluged from the wall socket. The charge may retain there for hours. So be careful.
If you have any more doubts, inform me through Fixya. Ok.

on mine, the screen/speaker module plugs into the player/base. note the power switch on the upper right side of the screen; this must be on as well as the main power on ( left side of the base). connect the power supply, power on; no other external connections are needed.
the screen can be detached and used as a low quality monitor; connect a/v cable & power supply to the right side of the screen, connect the other end of the a/v cable to vcr or whatever.

Good day to you. This is simply a loose base connector problem. The best way to tighten the base onto the monitor is to apply adhesive pastes like "mighty bond" or you can also tie a rubber bond onto it. Thank you and hope it helps.

If it is into the original box and you still have all the packing then first step would usually be removal of the monitor base.

With CRT monitors the base usually pushes to the back and it is best done with the monitor upside down so that you can check for any locking tabs that may need to be pushed open.

Once the base is off you will find it easier to see on the packaging how it should fit..

Drop the base packing into the box first and then the monitor followed by the top packing.

there is usually a space for the base on the top packing.

Just lay down the monitor, wirh the screen facing upwards and the swivell base facing your .
Press the four claps that are fixing the monitor to the the swivel base to release it.
Download the ACER AL1511 Install Guide if you need to.

Removing the base is covered in the manual. You can download a copy from HP here.

If I have helped you, please take a moment to rate this solution. Thanks for asking here!

At the base you want to remove - in order to pack the monitor - if you se at the rear left and right there are a tiny opening about 3 cm long,put inside a screw driver and it will open very easly the plastic cover.Then inside there are four screws,two on each side,remove them and the arm of the screen will be dis-attached.

Depending on the model the base would be removed by the clips on the underside, push them in and lift the base off,

if the whole stand comes off there will be a catch on the back of the monitor under neath/behind where the hinge connects to the screen, you may have to pull hard but don't apply too much force or it may snap

Hope that helps you

As per page 4 of the User's Manual from Acer:

Detaching the Monitor
If you need to repackage the monitor, please separate the monitor and base, and restore them to
the carton. To detach the monitor:
1. Unplug the AC power cord to make sure the power is off.
2. Pull the 4 hooks on bottom side of the base and hold.
3. Separate the monitor and base and put them into carton.
