My samsung syncmaster 940mw will not power up? It showed no signs of failure it just stoped. Tino


Good day sir, if it just stop, chances are it could be a fuse blowned, you may need to open your samsung tv, back panel. locate the fuse, replace it with the correct ampere value. if the fuse is in order, close the back cover. you have no choice but to bring it to your dealer for advice on your TV status.

19" Samsung SyncMaster washed out display


You either have a backlighting problem or the power supply is getting weak and starting to fail.
If you have another computer...connect it and see if the results are the same...also check your cables, analog and/or digital for any faults.
Good luck...i hope this helps.

No Display on my Samsung 204B monitor


If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

Black Out


Hi Detrix, Check with www.lcdrepair.net if you want a repair. Something is wrong with your LCD controller and or GUI interface circuit or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. These circuits take the Signal from the computer and controls the 2.5 million pixels on the LCD screen. Dsut can cause major problems with handling all that data. Give it a shot, what do you have to loose, its not dangerous if the monitor is unplugged.
