Component selection help - 17IPS20 repair
« on: May 27, 2020, 04:08:54 pm »
Hi, first post here, and I'm really rusty - haven't got my soldering iron out for years, so I'd like to check a few things before I bugger something up worse than it already is.

I'm trying to fix a 17IPS20 power supply in a telly I was given (schematic attached). The rectifier seems cooked and I can't get hold of RL207s at a decent price, so should it be OK to replace them with IN5408s?
IN5408 - http://www.farnell.com/datasheets/314353.pdf
RL207 - http://www.farnell.com/datasheets/1684861.pdf

Also one of the mosfets shows a short source-drain unpowered. I seem to remember that means it's scragged - or am I confused there?

Many thanks if you can help.

1N5408 is OK.
