Question about Samsung SyncMaster 204T Monitor
I turned on my samsung syncmaster 204t monitor last week and the power light came on and just stayed on, the monitor did not show any display. When I opened it up I found one blown capasitor in the what I figure to be the power supply,[possibly 2] so I replaced the three that were the same and reconnected the parts with the same results. Im figuring that the motherboard might also be damaged [or the bios chip] and I cant seem to find any parts [and since I dont realy know much about these things] I could realy use some help
Look for any bulging capacitors, instead of a flat top they will look "pregnant".
If you see any of those then replace them with capacitors of the same UF rating and the voltage needs to be either the same or higher.
If you dont see any bulging capacitors or burnt parts, then its got be the LCD at that point thats not staying on and the cost to replace the LCD is as much if not more then to just get another monitor.

savato321, Most black screen lcd monitor owners don't have the smarts to open up their monitors to do a VISUAL inspection of the "switch-mode-power-supply/inverter supply!!!! You're good. Now you will need to know some stuff about electrolytic filter capacitors! First, the "uf" or "UF" means micro-farad! It is just a rating given to express the storage capacity of the device. Next is the voltage rating. A 16v rating means that the capacitor should never be placed in a circuit where the voltage will exceed 10 to 12 volts DC. Your 820 uf cap rated at 25volts will most likely be in a 12 to 18volt dc circuit. Now for temperature rating. All caps have a maximum temp rating. Most clock radios, stereos, will use 85 degree centegrade rated caps. Printers,PCs,monitors, will use 105 degree C rated capacitors. Never replace with lower specification units! You can GO up but never DOWN. If 1000uf 25v is all you can get it's OK. If you can get 820uf 35v units and they are not too big and they will fit on the board sure you can use them. I would stick with the OEM design voltage rating. Electrolytic CAPS are polarized!! You must replace them + to + and - to -!!! If you screw -up they will blow-up!! The wire lead closest to the printed STRIPE on the cap will be the negative and the unmarked terminal will be the positive. If you visit www.ccl-la.com/badcaps.htm you will get more info on recapping your SMPS. You can also watch some DIY videos at YOUTUBE for "lcd monitor repair" that might be helpful. Also visually inspect the SMPS/inverter printed circuit board for "COLD" FROSTY looking solder joints. They should all have near mirror finish to them. Let us know the name of the BAD CAPS you remove from your unit. You may even want to document with pics with a digital camera what you find. Well, good luck guy. 12fixlouie

The glass of the panel is glued or welded to the LCD wafer below, it cannot be replaced separately. Since the panel is the most expensive part of an LCD monitor, its probably the cheapest option to just get a new monitor - spare part ordering and extensive manual work required for the change simply outweighs the remaining value of the monitor.
