No Power In Samsung LCD TV Repaired
One of the clients in my company called me to check on his 65” Samsung LCD TV and the complaint was no power. I went to his villa and tested the LCD TV and the problem was indeed “no power”. The challenge that I had was about removing the LCD TV from the wall. I managed to remove it and placed it on a soft surface. After that I removed all the screws and successfully opened the back cover.
The first component that I have checked was the main fuse and it was tested good. I further checked the main filter capacitor and there was 300VDC.
I continued to check on the standby power supply area and found a resistor 2.2 Ohm open circuit. This resistor was connected to the source pin of the TNY264PN IC (8 pins). All corresponding components were checked to be good. Since I do not have this part number I have used another part number TNY266PN. TNY266PN has higher specification than TNY264PN- see the below picture:
After the replacement of the resistor and the power IC the LCD TV was brought back to life again.
