Check each section with following method.
If there is a problem, replace or repair that part.
If it is not found, go to the next section.
Connectors
Confirm all connectors (PSU, Y-SUS, CTRL, Z-SUS). The
module may not function normally by misconnection (can not
send signal and power). Also misconnection for a long time can
have a specific board failed.

Exhaust Tip
Check the Exhausting Tip for cracks with the naked eye to
check the vacuum state.
If there is a problem, replace the PDP module by a new one.
In case of vacuum breakdown, the module makes a shaking
noise because of inside gas ventilation.
There may be a small crack, which cannot be seen with the
naked eye. This noise is different from capacitor noise.
