The blown out or up flyback thread.

[Buffett]

Hey all.

lets get a fun thread about your bad flybacks.

post your pics from your repairs only.

please list what chassis it was from and if you can remember when you repaired it.

the name of the game would be cool but it really does not make much difference.

i will start off by posting pics of a U2000 flyback off a chassis i repaired a couple months ago for an operator.

it just bulged out and looked neat.

Peace

I've only had one flyback failure on my games in 15 years I have been collecting. It was on the electrohome go7 in my Miss Pac-Man which is not a big surprise. It didn't explode or cause damage to anything else the monitor just wouldn't come on. After getting a replacement from Bob Roberts and putting it in all is well. I also replaced the horizontal output transistor at the same time which is good to do if your flight back goes. That was some years ago around 7 or 8 and the monitor has worked perfectly since.


Around 14 years ago technician co-worker friend of mine had been working on a baby Pac-Man just before I went to lunch. When I came back from lunch the whole shop was filled with it an acrid smokey smell. lt was very bad and apparently while testing the monitor the fly back exploded and the whole place just stunk.

The same friend told me of a monitor he was testing on a bench which happened to be an electrohome g07. The fly back let go and threw pieces of ferrite core up in the air and some of them lodged into the ceiling tile above the bench.

Holy hell! That bulge was all up in ma face (That's what she said ).

Was it arcing internally creating pressure?

I never took a pic after the flyback was removed but here it is. It's a Hantarex MTC 9000.
The pic date was Aug 7 2014 so I would think it was replaced sometime soon after, though the chassis had other issues as well.

I don't know how to embed vids but here's a flyback on a multi I used to have.

New G07 flyback. Ferrite core just missed my head and hit the ceiling.

that would have been a cool video to see it running and arching to the heatsinc.

K7500 Meltdown.

I've experienced one arching flyback... of course it was in a cabinet that was marked... "bad flyback". It looked and sounded similar to the one bottlejunkie posted above. I had it on for about 2 seconds.

Here's a fun one. Everything working except a very faint HV leaking sound:

Yikes. Melted A/C cable and broken ferrite:

That looks fully cooked.

What did it taste like?

Indeed; and a OEM flyback as far as I can tell. This is one of the worst I've ever seen.

lol. I've seen them do Emperor Palpatine shit over the years. but not like that.

This one scared the bejeezus out of me when it blew in half. The wife came running into the basement and thought I was dead.

Just happy I wasn't standing near it because it blew shrapnel all over the place.

I wear safety glasses anytime I power on a monitor (especially a G07) outside of a cabinet since then. I don't trust anything anymore.

I happened to be near a large underground transformer explosion last night. The force threw open the doors on the street. These things have a lot of energy!
