How to open case of Gateway 700G LCD monitor

I have a dead 700G LCD monitor. My problem is how to get it open undamaged. I am pretty much OK with fixing/diagnosing whatever turns out to be the problem inside, assuming I can get it open completely. Screws are out, and I got the screwed-down side to open up. But the top edge refuses to release, and I don't want to force it without more knowledge. Usually the screw side opens first... this one may be different. trying to get a knife or other thin object into the seam along the top was not productive, there must be a molded feature in the way (possibly to keep dust etc out). Searching here and elsewhere found no actual info. Most "how to" sites/posts/videos either were just about fixing the internal problem, had it open already, or did not seem to relate to the parts I am looking at.

    For added interest, the bottom of the case where teh screws were, is trapped by wires to power switch and cannot open very far. Following advice #1 resulted in loud "snap" and plastic pieces... not too many, but obviously the wrong solution, as the top of the case blocks access with sharp objects

  • Jerrold Tiers Oct 26, 2012

    Now I am being threatened with closure of the question, which is puzzling.... Anyhow, the case of this monitor is not responding to any of the suggestions. Before asking anything here, I had gotten the case open EXCEPT FOR the top edge, which appears to be as tight as ever. There isn't anywhere visible to stick in a device to pop it along that edge. The bottom is, as mentioned also restrained by the wires to the switch and some other part, so that it is rather obvious that it canot be opened up widely. Suggestion #2 and 3 do not remotely apply to this unit (sorry) and suggestion #1 , while it is likely generally correct, isn't really the answer. I basically knew that already... the REAL QUESTION is WHERE the specific items are that hold the top edge, because they are nowhere near as obvious as the plastic clips for the rest of the case.

    Well, it turns out that there is a trick to it. But I got it done.Thanks

SOURCE: I have tried to open the case of ViewSonic

Hello,

These units are more of a challenge to get open than most monitors. Here are the steps:

remove all cords - power, VGA/DVI speaker
remove stand - pull off hinge cover and then remove 4 screws
2 screws at bottom corners of case.
Now comes the fun part.
On the bottom edge there are 2 slits on on each side of the monitor about 3-4 inches in from the side. Use a small flat bladed screwdriver inserted in this slot to pop the two halves apart. Once you get a small gap just work your way around the entire monitor until the case halves are released from each other, but don't pull them apart yet. When opening most monitors the front comes off first but on this one the back case comes off first. You will need to again use your flat blade screwdriver inserted between the two case pieces and under the LCD panel and gently apply pressure. At the same time you will need to pull one end of the back case away from the panel, there are two plastic catches on each end that hold the panel inn the back case. One end will release then the other sould come right out so you can remove the back plastic case from the electronics. Now to get to the electronics you will need to remove the two screws on each end of the panel that hold the metal RF shielding in place. Also there is a screw in the center at the bottom of the panel that will need to be removed. Next unplug the 4 backlight power plugs. Slightly lift the shield so you can get to the flat ribbon cable going from the driver board to the panel. It will unplug from the panel by pressing in on the two release tabs, one on each end of the plug. Now you can get to the electronics. I am guessing you are having power issues with the unit. Check here for power supply repair kits if you need to get parts for your unit.

I hope this helps you get the case off, if so please rate my solution.

Gateway model 700g comes on briefly when powered on then goes black. Will come on briefly each time you power off and on


If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed GATEWAY monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

How to open gateway FPD 1765 LCD CASE OR BACK COVER


At Last! Okay this is how you open a Gateway FPD 1765 monitor. This Monitor open from the front first to reveal 4 screw under the black trim. Lay the screen face up, NOT FACE Down. So that the GATEWAY LOGO is looking at you. Carefully, lift up the black plastic trim slide a knife or slim tool, or your fingers will do,lifting the trim up a off. BE CAREFUL NOT TO BREAK THE POWER BUTTON WIRES, near the power on button. Then remove the 4 screw holding the back cover on. When you remove these screw the monitor is free, but careful there are 2 set of thin short wires that need to be un plug. You should be able to go for there.

My Gateway FPD2275W LCD monitor has just failed.


Trying to find replacement parts for your model could be a task. LCDs are so inexpensive these days it would be cheaper to just replace it. Not sure if you have a Frys computer store nearby but I saw a 22" LCD for 129.00. Check your local electronics stores also. If you did find the part for your Gateway consider the cost and installation fees.

My Gateway mx7118 lcd flickers whenever screen is opened,closed,


Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a dim image or flicking image on the laptop's LCD screen it means you have a backlight problem.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
Check out www.lcdparts.net for parts, repair service and DIY info.

You can check the fuse on the monitor and replace it. In case the fuse is OK check the cable connector, display card on the motherboard.

Dead LCD Monitor


Check if there is power voltage in the collector pin of the horizontal transistor. If there is voltage your power supply is good in the problem maybe is the high voltage section. but if there is no voltage i think your primary power supply circuit have a problem. Try to open the pin of the plyback connected to collector of horizontal B+ and open the computer . if the light indicator on the problem is maybe the plyback or the horinzontal section
