Re: Bad BN44-00264A PSU Board for Samsung LN40B610A5F LCD

Hi All,

Anyone can advise whether LP801S was normal or shorted based on the measurement or any other parts need further measurement.

Thanks,

Re: Bad BN44-00264A PSU Board for Samsung LN40B610A5F LCD

Hi All, my Samsung TV fuse FS801S on BN44-00264A kept blown when turned on. My is operating on 230v. I had measured all MOSFET and no short was detected based on BudM and others advise on measurement.
Meassurements:
1) CP801S and CP802S = 6.3Kohm
2) CP803 and CP8810 = 5.3kohm

Measurements on LP801S
1) connected to Bridge Rectifier - to + was 7.0kohm.
2) connected to Bridge Rectifier - to LB802 was 7.0kohm
3) connected to Bridge Rectifier - to RP801 was 0 ohm

Hi I am Dennismartin from Singapore.
My Samsung TV LA40B610A5M having power unit BN44-00246A FUSE FS801S keep blowing problem. Fuse FS802S was ok. Samsung do not want to sell the Power unit alone.
I got the circuit diagram from this helpful site and measured all before FS802S and all seems ok. The measurement for UP801S PIN 4 was shorted to ground and resistance btw CP804 and DD807 zero ohm too, shorted to ground. Was this normal cos of PR820?
Any advise how to go about from here?

Thanks in...
