Disassembly of ViewSonic LP2407 monitor case for repair

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?

    The LP2407 is also known as the FPD2485W. I am going to offer my own solution as I was compelled to hazard the dis-assembly blind. The part that gave me the most cause for caution was there are two notches in the bottom of the chassis with buttons above them. After an initial attempt to pry the chassis open at these locations snapped a piece of white plastic inside one of the notches I found an owners guid on line that described these notches as latches for the optional speaker bar. I was also momentarily confused by a hole with a lock symbol which I found out was a Kensington lock hole, merely a place to latch onto for an optional security lock --nothing to do with opening the chassis. The below explanation from Buddy Mcsparrin dated June 17, 2009 is the most applicable here I found. I managed to separate the two halves of the chassis without further damage and the notch I did damage was unnecessary to me as I did not have a speaker bar. The single suggestion I would like to add is, that there is a delicate ribbon attaching the front chassis to the touch sensitive control panel. It is unnecessary to disturb this ribbon because it is unnecessary to separate the front chassis from the body. After separating the two halves, pry the body from the back chassis only, leave the front chassis and the body together to avoid damaging this delicate ribbon. I will update this comment with photos later as my capacitors are on order and I will reopen my chassis.

SOURCE: How do you remove the outer case on Viewsonic VG930M-3 LCD

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.

SOURCE: NEED TO CHECK FOR BAD CAPS IN VIEWSONIC vp2130

Hello,
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.

SOURCE: Viewsonic VP2030b LCD monitor - No power

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.

ViewSonic VP201b with a black screen


hramirez, Retevo. com says time to retire this old monitor. Its that or you will need to do some extensive reading here on fixya on how and what to look for inside the unit that could be causing your black screen condition!!! Then you will go to YOUTUBE and view some of the many video clips that deal with "lcd monitor repair" and lcd monitor disassembly". Have you noticed any bad, swollen top, elcetrolytic filter capacitors on the units "switch-mode-power-supply/CCFL inverter printed circuit board?? How about any "cold" frosty looking solder joints around the component leads of the power transistors and ferrite inverter transformers? May need to get large magnifying glass to find those pesky little cold solder joints. 12fixlouie

My VA712 does not turn on, when supply button (mains) not from front panel, switch ON it shows blank screen (no sign of turn on) but when repeatedly switch ON & Off it Turns On & shows the display....


bholesir, If unit covered by ViewSonic warranty, USE IT!!! The units "switch-mode-power-supply" is in need of service!! Unit WILL require inspection and repair of possible bad (poor quality soldering) soldering of electronic components to the prinded circuit cards and or need replacement of bad (poor quality) electrolytic filter capacitors on the unit's "switch-mode-power-supply"/"CCFL inverter circuit" that have failed!! Do a visit to YOUTUBE for "LCD monitor disassembly" and "LCD monitor repair" so you can familarize FYI with what is inside your monitor, and possibly make a decision to do a DIY repair or contract out the work to a local TV/LCD monitor repair shop. If your pocket is deep enough, maybe you will repair and buy a new unit, keeping VA712 as spare unit for a rainy day. Read more of my responses to other owners in my FIXYA profile for more options not mentioned here. Good luck with repair. 12fixlouie

How do I open the case to access the fuses in my Viewsonic VX900 monitor?


custom_direc, I won't tell you how to "part" the plastic back "away" from the "front" bezel. You will just have to go visit YOUTUBE and check out the "LCD monitor disassembly" and "LCD monitor repair" videos that you might find there. But remember this!! YOU'RE ON YOU OWN!!!
Good luck in your quest to "find" bad fuses and or BAD, SWOLLEN electrolytic filter capacitors on the switch-mode-power-supply/INVERTER supply for the CCFL lamps. Bye for now. 12fixlouie

My monitor will turn on for less than a second, but then will go completely black. I've tried unplugging it and checking the connections, but nothing has worked.


mrtyler7, With monitor connected to a KNOWN GOOD pc that is displaying the WIN-desktop, then and only then turn-on the Viewsonic VX900. Note what happens. After LCD screen BLACKS out tell me if the desktop can still be seen if you point a bright flashlight 1 inch form screen??? You may or may not see the desktop depending on how far the "switch-mode-power-supply" has gone into SHUTDOWN mode to try and save it's self from a catastrophic faliure. Get back to me with result of test on fixya or by email. Also check out YOUTUBE for short video clips on "lcd monitor disassembly" or "lcd repair" or search web for stuff like "swollen caps" or "badcaps.net" or "bad electrolytic capacitors" !!! You may fall into this type of failure catagory. Let me know what plan of action you will be interested in. I will also let you know what other options you have.

When the monitor goes into sleep mode or is turned off, it is usually difficult to turn it on again. The on/off button has to be pressed several times up to 3 minutes in some cases to have it on again....


conodenalore, It's probably the power supply has failed or at best partially failed. Tech will most likely need to evaluate it. If possible connect a KNOWN GOOD monitor in it's place to PROVE beyond a reasonable doubt that the PC is good. You should also visit youtube and see some 8-12 minute video clips of LCD monitor disassembly and repairs of the top 2 causes of true monitor failures! Then get back here to fixya with your plan of action to effect a repair to your monitor. Only you can determine what to do! I'm louie12fix on fixya or lmistyrel @aol.com Bye for now.

Disassembly of case


This is for a Viewsonic VX900. The bottom bezel with the button unclips.Unplug the connector, and put aside. ( Dont pull on the wires) Then there are two screws that are removed, and the grey frame around the monitor comes off next. Then remove the 4 bottom screws, and the two top tiny screws and the LCD comes away from the back. Remove the shielding, and replace your components. Good Luck !!
