Re: need to remove dell e193fpc flat panel covers to...
First remove the stand. Then at the bottom of the monitor there are two small openings an inch or two from each edge. Starting there with WIDE flat blade screw driver (or a couple of them) it IS possible to pop the catches that hold the back of the case to the front. You have to go around the case very carefully popping each catch and preventing the areas you have opened from becoming re-latched. I found some wood popsicle sticks good for that.
If you search for "LCD Monitor Repair" you can find sites that have video's of several Dell models (but not this exact one) any that use the "pop open" case are pretty much similar.
One note after you get inside. The power supply board had the WORST solder job I have seen in a long time. The failure in the unit I repaired was due to open solder joints on the hi-voltage transformers taking out the power transistor's that drove them. It took me two months, but I found some replacement transistors on ebay and after resoldering many of the joints on the board it the monitor works fine.
I attribute part of the failure to the use of Lead free solder which is becoming common in all consumer electronics. It makes for brittle connections that fail easily and there is also the issue of tin whisker growth that will hit in a few years down the road.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
Well it is not that hard as it seams to be. First catch at Toshiba is plastic overlay above the keyboard it is cca 10 mm thick you should remove it with the screw driver carefuly. when removed you'll find screws unscrew them. After that remove hard drive and remove the cover for ram slots. Then remove all screws from the bottom side of the notebook. After that turn the notebook on the right side as you would do it normaly when using it. Remove the keyboard. After that remove all screws that you'll find under the keyboard. When done carefully remove the upper cover of the notebook. After that dismount the cables that come from the monitor to the mainboard and remove the screws holding the monitor brackets. Then you'll be able to remove the monitor. The monitor has litle rubber circles in every corner remove them. You'll find screws under them. Unscrew them and grab the plastic border of the monitor from the inner side and pull it towards you. So now you have removed it and the only thing that has left is to remove the side brackets you'll see little screws from the side - remove them and also remove the signal cable from the back of the monitor. When done take new monitor and do the reverse procedure.
Are you familiar with electronic components? Do you have technical skills and tools?
If yes, let us try fixing your LCD monitor by yourself.
Do you see where the end of the power plug connects with your monitor. The part where the power plug connects is the power supply section. To see the board assembly and its component you will need to open the back cover of the monitor.
To open the back cover, you will need a flat screw driver capable enough to separate the cover off the frame of the monitor. Careful, it is a snap in lock.
Once you have remove it, examine the power supply section. Find the blown / leaked / bulge capacitors and replace it with exact ratings and value. That will fix your No Picture problem.
Remember, monitor should be off when doing this. You will need soldering iron and pump to remove soldered joints of the capacitors. And soldering iron and lead to fix the terminals of your new capacitors.
After that, return the cover, plug the power cord, connect your monitor to your PC and turn it on.
Trek, if you do not know how to do it, it is best advised to bring the monitor to a certified technician to avoid injury and inflict further damage to your monitor. Good Luck!
Have you been to YOUTUBE for "lcd monitor disassembly" and "lcd monitor repair" video clips??? Absolutly do not use sharp cutting instruments to part the rear cover from front BEZEL of unit. One careless slip and it's a trip to local hospital "ER" to stop the gushing wound you have inflected on your body. Good luck with repair to your unit. 12fixlouie
simcraft's link was great ! It has pictures showing the dismantling procedure, but the document is in Chinese and so is the web site where it is located. Please remember that some internal components can retain a dangerous charge of electricity for a few minutes after disconnection from the ac outlet. Wait at least 5 minutes before attempting the disassembly. Try to find the service manual for any other LG LCD in your language and read the safety procedures - they are pretty much the same for all models.
uopftball, You will need to see some of the longer (6 to 10minute) video clips of "LCD monitor disassembly" / "LCD monitor repair" @ YOUTUBE and understand some basic principles of how a typical lcd monitor lights-up it's LCD glass panel. As for being the "same" concept as a laptop, Yes! and NO. Do you know anything about how the fluorescent lamps are lit on the rear side of the lcd panel? Changing a lcd on a laptop is not same as inspecting and repairing a switch-mode-power-supply or CCFL inverter (electronic ballast) power supply. The hardest part of monitor disassembly is removing the plastic rear cover from the plastic front bezel. There are usually 2 or 3 printed circuit boards( 3 in older) Inspect the SMPS for frosty looking COLD solder joints and bad electrolytic filter capacitors (swollen and possibly leaking) Pics can be viewed @ www.ccl-la.com/badcaps.htm and all over the net. let me know what you find inside the metal ventilated covers on rear of lcd panel. 12fixlouie
I just finished fixing my Samsung 193p LCD with similar problem. The problem was a black/blank screen as if it was off. But if you are going to use a bright flash light there was data in it. So I suspect it was the inverter.
1. Disconnect the power adapter and the D-sub cable.
2. Remove the small philip screws at the back of the LCD and remove the cover.
3. Remove 4 philip screws.
4. Disconnect the 2 data cables.
5. Openning the white cover is tricky. Use a flat screw driver and press it at the bottom middle part and use a credit card and pry from the middle part going to left or right side.
6. Remove the philip screws (black) around the LCD.
7. Remove the 4 philip screws and 4 at the middle part.
8. Be careful removing the switch cable. It is very fragile one of the 4 wires might come out (I did but fix it).
9. The Inverter board is at the left side. Take and remove the 4 inverter cables and the white wide cable.
10. This is another tricky part. Near the white cable there is a FUSE (brown in color). Check if it is open. If yes, You can use 2 think wires and solder on both ends. (Be careful the size of the fuse is soooo small like a half grain of rice). Or if you have a car fuse you can also use it.
11. Resolder the 6 terminals of the each transformer. There are 2 transformer so 12 terminals in all.
12. Assemble the parts back and you are done.
I have just did this here is the solution for you:
Philips screw driver
Small Flat screwdriver
Make sure your desk is clean and you also need a piece of soft clothes because you need
to place your LCD Monitor face down.
How to open the back cover:
First, remove all screws on the back cover, then, use a small flat head screw driver to
the plastic Clip inside the LCD Monitor star at the bottom of monitor. Then you can easily
separate the front bezel and back cover like the photos shown below.
