Repair Samsung 153V LCD monitor in question. Dim
One of the common problems in Samsung 153V LCD screen is dark when you close the screen and begin. The show under a dark environment, you see the current map. But it is very dark, when the button on the front panel display button on the screen. (OSD) appears and the proof is that the Board of Directors and screen control. LCD works and problems on the board inverter. Function of the inverter board is creating a pressure wave AC / DC power supply of the tube. The top and bottom of the LCD. When the inverter board problem, it will not shine and show what you see is dim.
I remember, as it constitutes an the first time the problem was recognized long ago and because of the lack of information, I can not solve the problem. I called a friend I asked about fixing problems. But no one I can. Answer, even if you surf the Internet for "Samsung. 153V LCD repair LCD Monitor dim" You will not find this reason I can own research, to find answers, and I loved Never give up Winston Churchill once said that "never give up never never." I leave the only solution to my loyal subscribers or for members only thank you for your support.
From Let 's now! When the cover and aluminum tubes were launched in the second. Filter capacitors arched the secondary power source for change. Value of 470 microfarads 25 volts and 1000 saw four more capacitors in the power of the SEC. Inverter to change the color and the value is. 47 micro-farad 25 volts Browse through all of my committee ESR meter I was a different error (calculated 220th UF 25 volts) is near the fuse (3amp) from the condenser is located on the same line fuse could, I assume that the fuse. How true, how good to check Ohmmeter, backups, see an open circuit.
We are facing real problems. Many electronic workshops with this model. After changing all the elements above LCD will not work still dark! First you need to ask why the fuse blowing? It is for consequential damages. shorted capacitors or a little more than network security? Circuit fuse is near the start Created consisting of twin circuit NPN and PNP transistors, digital (4 K7 4k7 resistor. Transistor). Some other LCD monitor designed for a combination of C945 and A733 in the Start circuit. By the Numbers. Samsung 153V transistors from the circuit A6J (PNP digital transistor) and A8J (NPN transistors, digital). Shown.
Sometimes, these Transistors is a problem. (Abbreviated) that caused the explosion. But in the case above the backup. Digital transistors are tested. Given that the two transistors must are now concentrated in four stood IC to drive high voltage transformers for 12 volts available to each IC of these are a set of four IC and the one that most manufacturers . Use 4532m board for some AD4E10 number and BBD3N13 While it is very difficult to find a datasheet or technical requirements of this get from web search.
You know this is the IC, or not. have created true Couples and P - Channel MOSFET N - channel. And know that you test the machine or not. Yes, if you're using component analysis. Atlas Peak, is He would like to be notified. Result is what you get. N-channel FET at Pin 1 (Source), Pin 2 Door (pin). 7 and 8 (drainage and the legs together). For P-channel FET, pin 3 (Source), Pin 4 Door () and pin 5 and 6 (drainage and the legs together). From the above tests, I found two. ic replace this short-circuited. Both the input shorted IC capacitors and fuse LCD back to life!
Another thing I wanted to share with this version that BIT1305 PWM Inverter IC is relatively stable and not a problem.
