Re: how do i test a schottky diode rectifier?
I tested this diodes out of circuit with fluke DMM in diode range & the reading is 0.174 but I see in utube by NorCal its 0.4, so I think the 0.174 is badLeave a comment:

Re: Toshiba 42rv530u psu, keeps blowing fuse resistor
Budm, I look at the diagram, check mosfets 820 & replaced the power IC q840 ( str-A6169). BTW I replaced also the resistor r850 & relay 81 when I plug the TV, the resistor r850 blown again. I don't know what my next idea.Leave a comment:

Re: Toshiba 47zv650u no power at all!!
I have the same problem, I change that resistor 1.8 ohms blown again. So I check the mosfet Q820 it's ok & the Schottky diode D872 & D873 are ok. Next I might check the small capacitor c849 I think it's .1 uf...Leave a comment:

Re: Dead toshiba
I have a problem also that the resistor 1.8 ohms keeps blowing, do think may be that's the problem also. BTW how do you check this mosfet...Leave a comment:
