(2)Donot leavethebrokenPDPSetonfor a longtime.Toprevent any further

damages,after checkthebrokenSet'scondition, makesuretoturnthe power

(AC)off.

(3) When opening the BACKCOVER,turn off the power(AC)topreventelectric

shock.When aPDP is on,highvoltage and highcurrentexistinside theSet.

(4) When loosening screws,check the connecting position and type of the

screw. Sort out thescrewsandstorethemseparately. Because screwsholding

PCBareworkingaselectric circuit GROUNDING, makesuretocheck if any
