Our Sony Bravia KDL40EX400 was a floor model, and the pedestal parts were lost in the depths of the store's back room (base is there - missing 2 connecting parts). We don't want to wall mount our tv, but I'm having real trouble finding replacement hardware. Any suggestions?

Check your local furniture store

Contact the autorozed dealer for Sony. They can provide you details of the screw. Gopakumar Gopalan Google

Hi there, there are many such on ebay

On a concrete floor these pedestals have a greater success than any other flooring. Nevertheless, more shaking will occur. One solution that has worked is installing "shake away" rubber pads with the pedestals. Not sure if there's an appliance parts store near you that carries this product. But like I said earlier, the fact that they are on a concrete floor helps.

Yes - just be careful with the ribbon cables. You are going to be replacing the LCD portion - behind it is the backlight assembly. Some may come with the entire assembly in one. You may need to do a little research to get a replacement - use Google to find a distributor.

Rubber feet may absorb rubbing alcohol to release the vacuum on the glass.

It doesn't sound like it would be very stable. Why don't you just call Sony and ask for a replacement part? They will usually quick ship you a part if it was not included at the time of purchase.

not a very sturdy pedestal, front loaders need concret solid base

If the pedestals are properly installed they pretty much become part of the washer and dryer and if those are installed correctly you will have no more vibration then if the units are sitting on the floor. If possible get the washer as close to an outside wall as possible since the floor is stronger there.
