Question about Computers & Internet
I am trying to disassemble the monitor so I can check the capacitors and repair it. The videos I find on this activity are not specific to the monitor and I fear breaking the case. Does anyone have experience with this specific model?

kauffman014, As far as opening the monitor up you may want to visit YOUTUBE and search for lcd monitor repair/ disassembling monitor/ or something like that. I did see a 9-11 min video there that was fairly good on un-snapping the rear cover from the front bezel of what I think was a DELL unit. Also visit electronicrepairguide.com run by a jestine yong. don't pay any attention to his ad to purchase repair course in lcd/fpd servicing!! only look at the pic's of the insides of lcd monitors and the power supply boards/inverter boards. On gateway's, and dell monitors the pedestal must be unscrewed from the rear cover first. The pedestal is really screwed down to the steel FPD chassis that covers the circuit boards and provides a ridgid mounting surface for the unit as a whole. Work on a flat surface with screen facing down on a blanket or lots of newspaper to prevent maring of the FPD!
There should be some phillips screws that fasten the steel shield to the left/right sides of the FPD frame. Once you get down to looking at the Switch-Mode-Power-Supply (smps) board look for large filter capacitors (electrolytic polarized aluminum can) that have the tops of them bulging upward as compared to normal ones that are flat. You will also need to inspect the bottom (solder side) of the board where all the leads of the components from the top side are soldered. You are looking for very thin hairline 'thermal' and or 'vibration' circular FRACTURES around the leads of the larger and bulkier (heavy) components. Yeah...use a big magnifying glass or better yet a 10x or 20x inspection microscope. One last thing, I highly recomend taking digital pic's as you disassemble the unit so it can be put together again without leftover parts. hope this info helps you out. Get back to me if you find out anything. I'm louie12fix on fixya or lmistyrel@ aol.com BYE for now.

The plastic case also has latches along the sides, top and bottom. Take a small flat blade screwdriver and go between the 2 halves of the case. The 2 pieces should open just a bit, now move the screwdrivers along the seam between the 2 halves. about every 2-4 inches there is a clip that needs to be released. You can release it by applying a small amount of pressure by each clip and moving down to the next one while pulling the case apart.

To disassemble your monitor follow these steps.
1. Remove the stand, usually 2 to 4 screws
2. Now there will be screws in each corner on the back of the monitor.
3. Take a small flat blade screw driver and seperate the two halves of the case. The front and back are held together by plastic latches spaced several inches apart around all four sides.
4. After the back case is off the boards you will be looking for are under the metal shield, remove the screws that hold it on.
5. Check my web site at www.ccl-la.com , we have pictures of what the bad caps look like if you are not sure.
6. Be sure to replace any capacitors that have raised and blown tops.
I hope this helps, If so please rate my solution.
If you need more info let me know.

There should be one fuse in the power supply inside. You can check and replace that if its dead. now if its not dead and you got power to that point you do need to rule out any capcitors at that time but if the fuse is gone it will not hurt to check the rest of the supply for the fault.
Please rate and accept the answer if it did help.
