When I turn the tv upside down to put the tv into the stand something rattles inside

The most common problem is a foreign object falling into the rear paper tray. Remove all the paper from the tray and unplug the machine. Turn it upside down and give it a good shake followed by a couple of healthy whacks on the base. See what falls out. If nothing falls out tip the machine (still upside down) vertically from side to side and listen carefully for anything rattling inside. If you hear nothing, put it all back together and try a test print. If the paper still jams or does not feed, see which side appears to be blocked and slide a flexible plastic strip along the back of the feed roller until you find an obstruction and remove it.

Tilt the machine slightly to see whether the screw is rattling around in the bottom of the sewing machine case. I've even turned machines upside down and shook them (be sure to put down a towel or something to stop the screw from bouncing and rolling into places unknown!).

Put it upside down on a towel and tighten the hinge pin screw right up inside the pedestal. It's in the middle & retains the hinge pin.

Hi, Can you turn the TV around. Maybe the stand was put on wrong...
Good luck.

if the head wobbles on stand, flip mixer upside down, and tighten the pivot pin screw way deep down inside stand. you will need a long flat blade screwdriver. it's probably loose.

Hi, i have instruction on removing your base stand.

Removing the Pedestal Stand
1) Carefully lay the front of the unit face down on a flat,
cushioned surface such as a quilt or blanket. Leave the stand
protruding over the edge of the surface.
Note: Extreme care should always be used when removing
the pedestal stand to avoid damage to the LCD panel.
2) Remove the jack pack cover on the back of the TV to expose
the pedestal stand screws. The jack pack cover can be removed
without tools.
3) Remove the four screws shown in the diagram below. This will
allow removal of the pedestal stand.
4) Once you have removed all four screws holding the pedestal
stand in place, remove the pedestal stand from the TV by
sliding the pedestal stand away from the TV.

Whoops, did you not use the right length screws.

The mounting bracket screws will short onto some electronics if you fit screws that are too long and from your superb description, it sounds like you did everything right but do not mention what screws you used.

Smoke coming from a TV is always a sign that something has burned out and unfortunately it is never a fuse. The TV will need fixing, there is no chance of it still working after it has smoked.

If you are lucky, it will just require a power board but you need a TV engineer to look at it as it is not something that you can usually do yourself. Even if you bought a new power board and installed it, there is no guarantee that the main board/processor board or inverter has not blown as well and this is why I recommend a professional looks at it.

Unless your house insurance covers the damage (if the excess is not too high).

try turning the bass down and make sure that the rattle is inside the speaker check around it and see if its not something nearby the speaker it could be something came off inside.

Since you did not specify a model I am going to assume you have a top feed model.
Remove the paper, flip upside down and shake.
Does anything seem to be in there rattling or fall out?
I had somebody bring in a printer for servicing because paper would not feed, turn out her kid was eating while standing over the printer. A half a pretzel came out...

But then this could have nothing to do with your problem

try turning your printers upside down as it may have something stuck inside it!!! i had a crayon inside mine which caused the same problems as you.
