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 !!

If it just fails to turn on, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not likely be able to do the repair yourself. 

Modern power supplies are designed to shut down if the current drawn exceeds the design level, which indicates that something the supply services or the supply itself has died.

If you are adventurous, you might pull the plug on the set, allow the set to sit overnight, gain access to the innards, and with good light, inspect any boards inside.
If you see one that has few ICs but many more larger discrete parts, this will be the power supply.
Again, before touching anything inside, especially on that board, allow at least several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.  
You are looking for components called electrolytic capacitors that are almost always cylindrical and mostly installed upright at 90 degrees to the board with leads passing through to the solder side.
This same type of component in smaller dimensions is still used in a horizontal package with leads bent down and passing though holes to the solder side.
The latter are becoming more rare since they don't lend themselves well to robot assembly.
Many failed caps (not all) will show signs of pregnancy when they fail, bulging unnaturally at the top when compared with others. Now and then, there may be traces of a crystalline deposit around the end where the seal failed from internal pressure.      
These will have values listed on them in uFd & VDC and sometimes, a plus/minus number lying about the precision.
Some also have a date code (rarer) that will look like four digits:
 
2403 = 24th week of 2003
 
Most electronics suppliers have a stock of the various values but if they have a date code at all, try to get only those made before 2002 or after 2006.

 
The larger caps will probably be OK since the failure is likely related to functions other than brute-force filtering. A pretty good 'rule of thumb' is to replace any caps you see bulging of any value but especially those that are 100 uFd or less.
 
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace it or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.
 
If you choose to replace failed caps yourself, you will need a quality soldering iron with a small, preferably iron-plated tip, rosin core solder and a sponge which when wetted is used to frequently wipe oxidized solder from the tip this should be kept bright and clean and fresh tinning will keep it that way.
 
You should also buy some solder 'wick' with the iron; this is used to place on the solder you wish to remove and then heated with the iron. Properly used, the wick will absorb nearly all of the solder from the lands from which you wish to remove a component.

Samsung SGH-X150 disassembly, take apart.


How to take apart Samsung SGH-X150 Black Cell phone:

16d4a0e.jpg


Time Required: 10 to 15 minutes.
Tools needed: Precision tools, Small philips screwdriver, Case opening tool or a plastic stick, or your fingernails.
Difficulty: Easy

Step 1. Remove the back cover, battery and sim card.

Step 2. Are you replacing the screen? Or are you looking into the keys or the mainboard?

If you wish to get to the display Go to step 3.

If you wish to get to the keys and the mainboard Go to step 4.


Getting to the display.

Step 3.
To replace the display, unscrew two Philips screws from the bottom of the display, they are under two soft tabs that you have to remove from on top of them.

Step 3.1. Use your fingernails or case opening tool to open the display cover.

Begin from the back and work towards the top, open the back and the sides, do not force open the front its held in place from there and you need to pull the plastic cover off looking at the picture below to the left

Step 3.2. After the cover is off, you get to the back of the display, on the top you have a few speakers etc.

Step 3.3. From the bottom release the connector by carefully pulling the board upwards.

Step 3.4. From the top, use a flat screwdriver to get the speakers out of their slots so the circuit board with the display comes off.

Step 3.5. The display is now free from the cover, you can remove it from the case.

Getting to the mainboard and keys.
Step 4. With the back cover, battery and sim card out. On the back of the phone, there 4 Philips screws. Marked with red dots.

Step 4.1. With the 4 small screws out, start using the case opener tool or your fingernails to release the plastic casing from the back of the phone. It is held in place similarly as the top of the phone in step 3. Begin from the sides and the bottom of the phone, the top is held in place and won't open until the sides and the bottom are lose, then you can disconnect the top part.

Step 4.2. As you release the back cover, on the side the up and down plastic key drops out remember to replace it properly when you assemble the phone.

Step 4.3. Disconnect the display cable, the mainboard is held in place by plastic clips on the top, carefully release the mainboard, you may break off a clip or two from the case, if that happens, no worries. The screws will still hold the casing together. the area is again marked in red.

By now you should have the phone completely disassembled / taken apart.

We are done.

Assemble in reverse order. Total 6 screws in this phone, 2 on display 4 on case. Held in place mostly by plastic clips.

Thank you for reading, I hope this has helped you.

My gateway M-1634u notebook screen backlight is not functioning are there any repair schematics available?


No, all that's available are disassembly diagrams.Looks like you have a bad "inverter'. Thisis a small circuit board (about 1/2inch by 4 inches) located inside the screens plastic case in the area just above the center of your keyboard. It has two small cables connected to it(one on each end).You'll have to take your screen off the laptop by the hinges and then open the screens plastic case with a small screwdriver.
Opening the laptop enough to get to the screens hinges is usually a job done by experience,since every laptop has a slightly different hinge mechanism and procedure for accessing them.

I am trying to open the outer casing of the vacuum


There is a push in type flat plastic switch trim cover over the metal housing surrounding the switch.. You must unplug the cord, gently pry around the trim cover and you will find a screw, an irregular one underneath holding the switch in place. DO NOT OVERTIGHTEN when reinstalling this one or you will crack the switch.

Once removed the rear housing will come off. Then you will see several new philips round head screws holding the front housing onto the vac.With all screws removed the housing should open easily but there may be dirty film inside holding the halves together. The fan shaft will unscrew revealing the fan, a spacer behind and perhaps two different spacer washers. Install the new fan hand tight, washers and spacers in same order...
Good effort figuring this one out. Please post back with results.

My headlight is out and I want to get the bulb out-how do I get to the hedlight?


I actually have a Acura CL 3.0 and changed the headlights on it 2 weeks ago. The first thing you do after propping the hood is start loosening the plastic fasteners (they should pop off). Once you have them all undone you can remove the entire plastic cover piece.
From there you can look to where the back of the headlights would be and see wires in a clip going into the headlight. There should be a little notch that you need to get the wire removed from the bulb. Simply twist and the old bulb comes out and you just follow the same steps backwards to get the new bulb in.
NOTE: There is a gel you can place on the inside of the plastic adapter to help your bulb from overheating and frying any wires/bulbs.
