Look at the power supply caps first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Samsung smh2117s. The display does not light up, however the touch pads all work. How do you get the light back?


SAMSUNG SMH2117s is a Microwave oven.. :-D
you're in the wrong section. This is for mobile phones.

But, may be the display is gone if you cannot see any lights(Assuming the Microwave oven itself has a LCD to display temp, time..etc.. I don't actually know the model. But many Ovens are digital.). In this case, do not dismantle,crack open it. This is far beyond a rookie operation.

Very dim display..so dark that all I see is a faint picture. Are bad capacitors to blame?


I would say either the video cable has disconneted, causeing the led that lights the screen up to not function,, simpley take the bezel around the screen, take the small screws aroud the screen to slightley pull the screen away from the back top to see if the cable is, or has pulled loose...If now the screen is bad..

SyncMaster 930B takes 20 minutes at least to become visable


IT SHOWS THAT THE PROBLEM IS IN THE POWER SUPPLY SECTION OF THE LCD. CHANGE THE CAPACITORS PLACED IN THE POWER SUPPLY SECTION. IT WILL WORK.
DONT FORGET TO VOTE.

hello,

firstly backup all contacts and e-mails etc before fixing this issue.

if your operating system or configuration files are missing then you should try re-installing from the following samsung download site-
http://www.samsungmobile.com/support/omnia/index.jsp

if this doesn't work try a hard reset by pressing a pin or pen into the hole adjacent to the power button.
