good video. However to be specific the board you are working on is from an LED TV and not LCD. There are no flourecent tubes in the TV but smd LED lights.
I have same power supply board. And i had replaced MOSFET 10N60, and 68/450 main filter. But after two days same problem comes. MOSFET shorts again. Whats the exact problem?
@@mungelectronics7601 Great video thanks,i have a Lg 32 ln 3500 that has no volts at all anywhere ,fuse is good as most components ,could it be the mosfet only?thanks
my PS51F5500 gave loud pop sound, then totally OFF, red front led ON for few seconds then off , green light at the board blinking slowly. I am not sure which board is the isue.
This phenomenon is due to a damaged component, so it reports to the processor. You should check the voltages at the mainboard and the t-con board. Good luck!
Sir my tv model lg lcd 32cs410-tb Not on even red led not glow I check on supply board 2fuse 1 is ok 2 is short i jointe the fuse by small wire fuse again short. Then iwill chech 3.5,12,24 vt also missing back the supply board 2 mosfet both are beep show on diode mode. Plz suggest me what to do. Sir str power supply moduel can work on lcd power supply or not.
You remove the MOSFET and remove the opto of that transformer and then attach the Chinese 3-wire TV power board to it as follows: the red wire you solder to the D pin position of the Mosfet, the black wire welded to the Ground of the primary part. Then you adjust the 3-wire power potentiometer for the secondary output voltage is enough. Good luck.
Hi sir im frm tamilnadu chennai, you doing this lg pwr bd fault that same complaint i also did set running but that mosfet shortage happen after 1 week or 10 days,pls give me permanent solution
You should to replace the input capacitor, the input capacitor of this board is 68MF, you have to replace the new capacitor with the capacitance about 100MF. I wish you successful.
