Re: Electric blanket resistor

pic, mains cable is at right end, the pic turned 90 degrees when i uploaded it. no idea of wattage, no labels anywhere. think label came off years ago...

Re: Electric blanket resistor

Hi, thanks for response, I have now included a pic of inside of controller. the component fits in the holders either side of the white mains cable at bottom. quite a primitive design. one time it stopped working because the component came out of the holder at one end, which could happen just from knocking the controller about I think. I don't know much about this kind of stuff. I assumed all colour banded stuff is always a resistor. I am learning. Thanks

Electric blanket, can't find name on it anywhere, think label came off years ago. Double size, some years ago one side stopped working, I found a resistor had failed in the controller. As I don't use my side of the electric blanket I turned it round so my wife could use the good side. Now the resistor has gone in that side too. Well I think it is a resistor. The mains live wire goes on one end of this component and then the other end goes to the workings of the controller. pic of the component att'd . stamped in the metal is F400H250V . I don't know what F400H means. 250V presumably means 250...

Re: Fix for Benq FP737s 17" (Q7T3)

thanks for replies. I got 6 of these model of monitors from a pile of rubbish being chucked out of some offices. they all have labels on them saying faulty, but one of them seems to work fine (perhaps an intermittent fault?). i dont have much time at the monent to work on them but will get around to taking them apart someday to gibe me the 'challenge' of fixing thwm

Re: Fix for Benq FP737s 17" (Q7T3)

i have one of these monitors (benq q7t3)with the usual problem. I have not tried repairing monitors before, but i have recapped loads of dell motherboards (gx270) so i know what i am doing with a soldering iron.
Please answer this
- exactly how do i test the transistors to see if faulty?

Do the transistors have to be removed from the circuit board to test them?

Are all transistors tested the same way or are different methods / readings needed for different types.

I note the fuse is...
