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?
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.
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.
@@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!
You are a good teacher. I wish you had more videos like this
I like this video
Very good sir
Thanks a lot from Ghana, i want you to teach me privately master
How are going to be teached master
Thank you for video is useful, you're a good teacher

thank you for video
I like this video, this video is useful
hello good video
Sir you are goog technicien so,if you have thé schematic diagramme for thés power suplaly thank you
Yes, I will
@@mungelectronics7601 hi,ould you want to sens it to me.tanks.
Thanks master for sharing

tnx for sharing master
You should make lots of videos like this
okay
I want this board. While mybord connectig mother board 24v drop out 13volt so what is complaint sir?
You can replace the filter capacitor and rectifier diode of 24v circuit. Next, you can find shorted component. I wish you successful.
hello freind thank you for this video , please what is the brand of the desoldering pump please
The heatsink compound on the FET Transistor not sufficient to transfer the heat to the heatsink?
The manufacturer designed it like that, so it's very good.

How can i purchase mosfet
You can remove the old one and go to the electronics store to buy it.

My television is completely dead, it's to old
Now there's recessed LCD TV, is that right?
Right
In a few years, everyone will probably only use LCD television
I think so
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.

Great!
I fixed it, but problem comes after 25days
Hi
Now LCD TVs are using a lot
yes
