Check the picture below to find IC101 part number. It appears to be a 3.3 voltage regulator.

Model LN52A550P3FXZA. Video and audio cycle on and off every 30 seconds or so. When picture switches off, the screen is filled with multi-color horizontal lines.


It is a common problem for this model, the problem is the main board. There are 2 Tantalum capacitors (C102 & C131) 47MF/10V, 1 Passive Voltage regulator KIA7805AF (IC300), 1 Step-Down Power Conveter IC MP2363DN (IC101) need to be replaced. If you do not have soldering skills, just order a new board.

If a fuse blows like that there is a major problem, inside. I suspect that what your are seeing is the inrush thermistor, and they exhibit this under great load. I would explect that this fault maybe in the actual PSU. Due to the lack of service manual support, i would get a quote for repair from an authorised service center.

Sounds like your filter capacitors are bad or weak and some 60hz ripple is getting through. If you have an oscilloscope, check the output to see if there is any ripple voltage.

Power led blinking red and green wont turn on


For LG DU-37LZ30 specifically - On the power supply board, look for IC101, an 8-pin DIP IC. There will be three smaller electrolytic capacitors near it (C107, C113 and C125) marked 47uF, 35V. I'm being lazy here, but replace all three (only one is the real culprit). What is happening is that one of these caps is charged by line voltage until the IC (power supply controller) can start running. When this capacitor gets leaky, it cannot reach the proper voltage to start the controller. I used a 47uF, 50V replacement.
I have fixed two LG sets with this same problem. The other was a 26". It's a cheap fix!

There is a bad capacitor on the circuit board which is quite common. The IC"s usually need to be replaced. The convergance is off due to these faulty capacitors.

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
