Samsung Synchmaster 940MW - Will no longer power up.
There's only two circuit boards inside - power and main board. I think the power board is shot. Couple of electrolytic capacitors look to be swollen, leaking. Is there a place where I can buy a new module or get this one repaired?

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board
hit your MONITOR lightly on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some monitors on main board ( also on CRT circuit board ) at some soldering joints crack develops....then due to loose contact picture becomes small in size or abnormal width,etc ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears for some time............so solution is ......monitor main board & CRT circuit board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting monitor lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again ................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good monitor service engineer .............iam from bangalore - 09986222774 - firstname.lastname@example.org ( computers, laptop, printers, etc )..............

A wild guess here is that the optrics board has failed. If you take the back off can you smell burned electrics. look on the circuit to see if you can detect burn or browned capacitors. Depending on age and value of the set it might be time to replace it.
