Greetings, I have a Samsung Syncmaster 3D HDTV TA750 (Model No.:T23A750) and I recently lost it's power adapter. A replacement adapter that I bought did not work as the screen doesn't turn on at all. That's why I need to make sure this replacement adapter is specifically compatible with my monitor. If you could kindly show me where I can find one, I would be grateful! Please note that I live in the UK. My screen has a note 'DC14V' where the adapter goes in. Thanks in advance.

Hi inkedpandora, http://icm.computercci.com/pgi-productspec?PSO080 This one should work for you it's the same voltage and amperage as your unit. 19VDC 3.16A Any standard power cable from an old printer or computer will work with one of those PS's. The only thing you need to check before you buy is the polarity of the barrel connector. I looked on the net but could not find out that info so look at the jack where the power plugs into the monitor. You might see a little diagram showing a + and - signs. If the line coming off the + sign goes to the semi-circle than the barrel is positive and if the - goes to the SC the barrel is negative. Ask them before you buy which way that one is. As long as they are the same you will be able to use that PS. Good Luck, Dude

Hi this is the way how to examine
what's wrong with your LCD monitors. After you turned it on and the screen
blacked out or stopped working, you have to check that if you can see the image on the screen or
not by shining a flashlight into the screen, not directly but find the best
angle to the screen and take a look very closely. If you can see the icons or
any image, there will be a minor problem. This is because of the lamps inside
screen. Some of them were broken and it is very easy to replace. If you cannot
see anything on the screen, there'll be some problems with inverter board. If you
have soldering tool and want to fix it by yourself, check the caps first. It
may cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.
Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

Try to replace C110 and C111 in the power supply circuit. These are 820uF caps and are in parallel. I had slow start and a flicker on this same monitor. Replacing the caps fixed it. Good luck, Ryan

hello i have the same problem, there are 4 lamps (bulbs) inside the monitor when some of them falls the system turn off, cheks and good look

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
