Hi...again...I like it here

Got a 17pw26-4 both fets (q813/q814) have s/c'd  and was wondering how do you test IC830...the IC is a fan7711 do you test in circuit/out of circuit and what pins do I check with DMM so you confirm its fubar'd

Thanks in advance people

Hi Scoob ..
If its directly connected to the blown fets ..I'd be inclined to just change it for what it costs ..
but if it helps ..
Here's the pdf

Cheers for the pdf Evan...just a shame I cant read latin  :57:

Thanks again

Situations like this is where I'm a great fan of stripping components from old boards to give you a ready supply to try, by all means replace with a new component once you've verified the fault but saves buying a lot of stuff on a what if basis

Scoob.. pin 4 ground pin5 low output pin 7 high output so test 4 to 7 for an output and 4 to 5 although depending on input load etc it isnt always as simple some wont switch unless under load so it is as evan said sometimes easier to just pop a new one in.... ah... come back valves all is forgiving .. if it lights up its working ! who needs a bloody meter !
