Hi experts, My Philips 150B3T 15 in. Flat Panel LCD Monitor blows the fuse as soon as I plug it in. Any ideas on which components to check? Best regards, Mark

Yes you can. This TV has both VGA-In and component in support. The only thing you need to change is the input you're using with your remote control. As easy as changing the channel!

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.

I have a flat panel lcd 19, it doesn't power on

Don't know what model you have, but I would check the fuse first. It should be marked with a Fxxx where xxx are numbers. Sometimes the fuses are glass, others times they look like little surface mount chip types. If you find that a fuse is blown, does not mean that just replacing it will solve the problem, you need to figure why the fuse has blown, typically the FETs short out. Hope this helps.

No power when you plug in monitor. Nothing happens.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 HP and other monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My monitor wont turn on HELP PLZ!! URGENT!!!

Yes, sometimes replacing Fuse which can be found at the back of the monitor, will help. Or else, you have to open the monitor and locate the fuse. Bring with you the busted fuse to your local electronic shop for correct replacement.

Green Light Blush then nuthing on the screen

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU1.gif and monitor. After it went blank, you have to check if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like mine, I can see window image using flashlight and check lamps inside. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
Thank you,

Monitor goes black

it depends whether it displays anything. There's only one fuse which determines if the power is on or nor. If your monitor turns on, I would not look for the bad fuse.
