my daughter's 3 year old SyncMaster T190 monitor developed a fault last week -it switches on ok, perfect display for about one minute, then the screen goes blank. It's the same with either DVI or VGA input.Switching off for a few minutes enables the display again, for about a minute.
Other Samsung monitors exhibit similar faults, mostly due to blown Capacitors.So, rather than junk the T190, I decided to open it up and check for damage capacitors.
But how to dismantle it? After spending over an hour searching the web, without success, I had another go.
Here is how:1. remove the foot dish (undo butterfly screw at bottom)2. swivel the remaining stand post RIGHT back, as far as it goes (it may be quite stiff, I had to use WD40)3. stand the monitor on its top edge, you can now see 2 small cut-backs on the post, where it enters the monitor case4. use a small Philips screwdriver and remove the two screws hidden there5. remove the screw holding the two cover halves of the post together6. remove the covers7. the metal core of the stand, with its hinge part, is now exposed8. pull this out (NOT easy!); the part inside the monitor is shaped like a spade and is a very tight fit! I tapped it with a small hammer while pulling hard.9. when it is removed, you can access 2 screws that hold the bezel and housing together.10. gently insert a small flat screwdriver all along the four edges of the bezel and snap it apart11. the remaining parts can now be dismantled; some cables need unplugging (make a note of polarity!)
If anybody needs more information, please email me, I have taken some photos
PS - all capacitors were ok, I've no idea what's causing the fault.
