20 Most Recent Samsung SyncMaster 153V 15" Flat Panel LCD Monitor Questions & Answers


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

It is either the Inverter board inside or the ccfl is faulty. Don't waste time, not worth to repair.

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

check caps on the power supply and replace with good and of the same rating. if not then maybe your backlight is gone

It sounds like the backlight inverter circuits have gone out, or the lamps assemblies.
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

It seem that you have a problem in your video card. Try to re-install the driver disk of your video card.

Press the auto key of your monitor to get the best fitted resolution for your window, each monitor has a limited graphic capability of which it is designed. if the production is not ok consult your manufacturer.

If your motherboard doesn't have a VGA connection, then that means it most likely does not have an integrated video card. If this is the case, then you will have to purchase and install a video card. It is very easy and your local Best Buy should be a great resource. The geeks there are usually very enthusiastic about explaining how to do it. I use to order from newegg.com, but they have become very commercialized and overpriced, like Best Buy. You can check tigerdirect.com or my favorite Amazon.com. Best Buy will price match any items they sell, including those on Amazon.
