Csi sp-6c removal

That doesn't exist. It is a $45 flashlight with a knife blade and powerbank access via the battery in it. Just one screw to remove the blade as shown on Amazon. You could ask the maker in China?

Never herd of wall tiles cracking. If you have access to the underside of the bathroom (via basement ceiling), you may want to check of the wall(s) has proper support for load or a non-supported floor plywood joint may have been installed the wrong way/not supported properly. You should be able to see the nails coming through the floor plywood where the wall(s) is located above. You may have to add blocking and/or brace(s) with joist hangers for support as required. Interior wall studs may also been spaced at 24"c/c instead of 16"c/c if the wall tiles were not installed by the builder not accounting for heavier than normal load.

If by chance the washroom is in the basement::

• Non-load bearing walls (interior non-loading will be supported by the slab.
• Load bearing walls will be supported by footing foundations

As for your toilet moving: the wax gasket may need replacing if not seated properly (rocking). If it just seems a bit loose, try to just tighten the flange bolts on both sides of the bottom of the toilet after removing caps. If no spacers are present between the bolts and the ceramic, they need to be there to not crack the base or reduce the chance of over-tightening that would do the same. There may be water coming from a shower that's close by or from the sweating of the tank in the humid summer months.

If the ceiling are closed for access below, you have the choice of tackling the job from within the bathroom by removing the some of the plywood floor to inspect the problem OR by the ceiling below. I would should the ceiling below if it was me.

Good Luck!

Most likely it is a rubbing voice coil in either the midrange driver or the tweeter. The only way to repair is to replace the bad driver or tweeter with a new part. Contact CV for replacement parts costs. Replacing parts in most speakers is usually easy to do if you have rudimentary tools and skills. Most connections are made with "faston" slip on/off connectors so a soldering iron is usually not needed.

ARE You talking about right above your head in the headliner? this is actually a fan to help vehicle know inside temperature. they will come loose sometimes and make noise need to drop headliner down and see if you can reattach may need to replace fan,it is a 1-2" speaker cover in headliner

Either wax ring or sewage pipe is leaking. If you cant open the ceiling from below to look for leak you may have to remove toilet inspect pipe and look to see if it was leaking from wax ring and if it could have gone downstairs without leaking out too. If leak couldn't have come from wax ring the leak must be coming from a pipe in the floor. Find the simplest way to access it to repair it.

The floor/roof loads above will be a bigger unknown than the ceiling itself. The wall MAY be replacable with properly sized beam/column combinations but you will need to have a design professional look for adauate footing size, calculate floor loads (and roof loads if any), and size the beam/column system to support ALL of the loads now carried by the wall. If you have access to the origional floor and roof framing plans they will be a great help, otherwise someone will need to do some investigating to make thoes design judgements.
In 23 years working as a building inspector I'v seen way too many structural problems caused by inadaquate beam installations, Its worth the time and money to do it right.
Good Luck.

as far as i know the tweeter is angled in the mount it does not look like the speaker can be angled as it appears to be fairly standard ceiling unit.

but the cover looks like a push on so maybe very careful levering might work.

That is a check the speaker wire error, caused by a short or perceived short. If you look at the back of the receiver you may see 1 strand of the wire loose, they are very hard to see sometimes. You may use banana plugs as it is painful to get everything hooked up without a few loose strands.

If there is still the issue check your speaker connections for the same issue. If they are in ceiling/wall speakers disconnect them all then plug them in one at a time to narrow it down.

If the issue persists perhaps one of your speaker wires has a short somewhere, could be a misplaced drywall screw from hanging a picture, or a carpet tack strip, or a pet deciding it was a nice chew toy.

If you are completely sure it is none of those then I would say it is a bad speaker or receiver. Try changing in and out known good speakers/receivers if you have access to them to see which one it is.

Good luck
