I was also really glad - especially the exchange of the small FAN7530 (SOP-8) was difficult. Only possible with hot air from my soldering station - first time usage.

It was impossible to get these parts in Germany so I ordered them in Asia. Today arrived last parts. After changing all parts the TFT works as well as before.
Thanks all for your help!!!

Re: Samsung 24" power supply BN44-00195A first stage voltage?
I checked the ICP801S and it really might be shorted. I think it would be better to replace the parts of the PFC:
ICP801S - FAN7530 ? (bad to read)
QP801S - FCPF11N60
DP802S - F10UP60S
QM802 - FQPF9N50C
QM803 - FQPF9N50C
Is it right?
I really hope that the psu will work after replacing these parts.
Otherwise - sh.. and thrown on the scrap heap.

Re: BN44-00195A. Fuse keep blowing, MOSFET constantly shorted, Transformer burnt

@Toasty: Thanks for the tip. I thought the main cap will never die - i will test it. :-)
Bulb test too...after washing with alcohol...Leave a comment:

Re: Samsung 24" power supply BN44-00195A first stage voltage?
I have removed the glue completely - also from the blue caps. The RM801 was blown and the QM802 shorted. I replaced these parts - after power on RM801 blown again. I have no idea what else i can do. :-(
I read something about a shorted transformer on TM801. Might this be an option?Leave a comment:

Re: Samsung 24" power supply BN44-00195A first stage voltage?
Hello everybody!
I have the same problems with my BN44-00195A. It's from my 2493HM. He stopped working with an explosion. Looking at der power supply i found a blown resistor RM801 and QM802. Both became new.
After switching on the power supply there was an explosion too. The RM801 was blown again - also the fuses at the psu and the fuse of the room.
I have no idea what else i can do. Can anybody help me?
I hope my english is not too bad.Last edited by kusarigama; 10-23-2012, 07:55 AM.Leave a comment:
