The Foam Bars

To put the TV set in its service position place it upside down on
a table top, use foam cushions or a protection sheet.
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. By laying the plasma
or LCD TV flat on the (ESD protective) foam bars, a stable
situation is created to perform measurements and alignments.
By first placing a mirror flat on the table under the TV you can
easily see if something is happening on the screen.
Caution: When using a sheet, the plasma screen can become
very hot. Therefore, it is advised to use foam cushions
