FS5: Mounting holes on top shallow, fragile and downright dangerous!

P1040030.JPGP1040033.JPGWe used a Noga arm to mount a Shogun to the top plate of our FS5. While tightening, the mounting screw actually pierced the top plate (very thin aluminum), entered the camera and caused physical damage to an internal flex cable directly beneath it, causing electronic damage to the main board. Of course, Sony wont cover the warrantee. We had a zacuto cheeseplate on top but this screw went into one of the exposed mounting holes on the camera itself. These things are meant to be used, but man they are fragile. And you have to wonder why such a vulnerable cable would be directly in line with a pressure point - the bottom of the mounting hole just popped right off. BEWARE!
 
You went thru the chassis plate. I dont see the damage - you seem to be pointing to a ribbon cable. Is that the effected component? I cant really see damage - it's probably crushed wires that dont show up? This is probably not so bad to fix. Need more info about damage tho - and what the result on camera function is.

I made the Shotgrip tophandle for the FS100 awhile back and we ofcourse planned our dimensions carefully so that our studs landed shy of the chassis. When using third party kit - you need to be really careful of stud lengths socket depth. measure depth if worried! stick something in there you can hold beside the stud you are using to compare. A wise old engineer once told me you need 3 threads for a good bite. he said that was the minimum but it was also as good as a 1000. sweet spot. I'm really saying this for other people reading this - not trying to be a smart ass after the fact.

Sony chassis are way underbuilt. I once splayed an EX1 wide open when wind hit the tripod - what a mess. it is sickening how soft they make the housings. What do they think we do with them?
Pick grapes?
 
I managed to blow it up and got a better look. Obviously a problem there, you've fused prob 4-10 comm wires. replacing the ribbon cable is probably doable thru Sony parts
but damage to the main board? was it pwered on when you fused the ribbon cable? did you power it up after? how do you know the logic board is damaged and you're not just seeing the effects of this shorted cable?

Authorized Sony Service Technician took the pics and quoted $2,500 parts and labor. He's the one who told us the extent of the damage. And that Sony wouldn't cover it. We didnt know it was an issue til we tried to power up and could not. And didnt know we had gone through the plate until it was pointed out to us. The big issue is getting the parts - the ribbon isn't a standard part item like a switch or an input. And there was an earthquake in Japan that put Sony way behind in getting parts. Insult to injury. :Drogar-Mad(DBG):
 
Sorry. That's rough and Ive been thru it. Those sockets are meant to attach any manner of third party gear. They should use a sacrificial plate of some kind to protect vital components from simply over tightening into the provided socket. It's worse than forseeable- it's an expectation that is bound to happen.

C'mon Sony! Help this guy out!

Sorry to hear of your troubles with this. SONY should have anticipated gear being attached to those mounting holes, and allowed reasonable clearance for a variety of popular attachments. I think SONY didn't really think it through and you shouldn't have to pay for their short sightedness. I had a similar problem with a 1/4'x20 screw mount on the bottom of my Tascam DR40 recorder. I hope your repair doesn't take long.
 
Good goodness... sorry for your loss

Those mounting holes are annoying to begin with... too close to the handle and... yeah, always a little concerning securing anything into them. Recently got the SmallRig top cheeseplates and doubly happy now that I did.
