Samsung 153V LCD Monitor Power Supply Repair Tips


Troubleshooting Samsung 153V LCD power supply is just like troubleshooting those CRT type. This monitor came in with no power symptom. If you are first time repairing this type of power supply, I recommend you to first remove the switch mode power transformer. Then test every single component in the primary section, before you continue to check the secondary section.


You have to be good in testing basic electronic components in order to detect the fault. You can always browse through my website just in case you do not know how to test basic electronic components. If you do not know the right way to check, you might miss out a bad component and this will lead you not able to solve the problem. After carefully checking all the components in the power supply section, I found the filter capacitor do not have any reading using digital capacitance meter (open) , the two round type fuse also open circuit, 1N4744 15 Volt zener diode short circuit and lastly the power IC TOP247F blown!.


Testing the SMPS (switch mode power supply) primary winding with a **** smith fly-back tester, shows green bar which indicates good winding. What we left here were the secondary diode and filter capacitor. Upon checking them with analog meter and ESR meter, found all of them to be good condition. Other area like main board and inverter board also looks okay (Power failure rarely affect these two circuit). Now we have confirmed that only five components found to be faulty.


One by one the components were replaced (except one fuse) and just before you switch on the power supply, make sure you connect a 100 watt light bulb across the live ac line. Once it is done you can then proceed to switch on the LCD monitor to look at the brightness of the bulb.

If it very bright, this suggests that there are still short circuit somewhere in the power section. If it dim or totally goes off, you can now place your red probe to the secondary side to check if any dc present at their respective line. If there are DC voltages present at the output, you can switch off the power, discharge the filter capacitor (for safety purposes), remove the light bulb and connect back the new fuse to its original location.


You are now hundred percent sure that the LCD power supply won

My samsung sincmaster 153v black screen but still a picture


Time for a new one. Most likely the inverter for the backlight is burned out. It's not a difficult replacement but by the time you've located one, paid for it and spent two hours replacing it in a monitor that old you've spent more money and time than buying a brand new 17"-24" would cost. Time to treat yourself to at least 1920x1080

You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
