Dont look blown, or when you pulled them and checked them with a multi meter they tested good? Never trust your eyes for checking a fuse.

I have not done a lot of repairs on Sterns but I thought I read recently there is a little LED next to the fuses in the backbox which tell you they go out.

Also the game was on when you did this?

F4 is out. Replace it.

Fuse puller works great.

LTG : )™

F4 shows no LED; and is next to your GI lighting block. Pretty good bet that's the one.

They make fuse pullers. They also make pliers with notches for fuses (love mine). Some people just use a screwdriver to pop it out (remember, that's glass tho).

Make sure your machine is OFF when you do pull it.

Got a multimeter? Make sure the ohmmeter says 0 ohms. Or if it has a buzzer for continuity checking, use that mode and listen for a beep. This check MUST be done with at least one half of the fuse out (so that it is not "in circuit" with the other stuff).

Good bet it is blown. Replace it (look for the correct fuse!), and replace it. See if that's a quick fix, or if something else blew. Hopefully the fuse took the hit for the team, and failed fast enough to avoid further damage.

Your F4 fuse looks blown, notice the red LED is out. Turn power off, use a tiny screw driver and pop that fuse out. Check with a multimeter in ohms mode for resistance, should show resistance if not, replace the fuse with the same amoerage/voltage rating that is listed in tiny writing on the fuse, you can double check itbin the manual.

Cable tie! Best fuse puller Eva!!!!!!

The other folks at the museum laugh, but I use this for pulling fuses. And it is wonderful. Especially when you're pulling literally every darn fuse to make sure it's correct to spec.
