Question about Sony KV-40XBR700 40" TV
MAKE SURE NO SPEAKERS WITH BIG MAGNETS ARE ABOVE OR NEAR THE TOP OF THE SET--magnets can cause "purity" problems.
The set has a built in coil to correct this every time you turn the set on.
IF THE SET IN THE MOVE FELL FORWARD, IT MAY HAVE DAMAGED THE SHADOW MASK INSIDE THE TUBE.....
TWO REASONS FOR YOUR PROBLEM: COIL IN SET NOT WORKING FOR SOME REASON---ROTATE SET LEFT AND OR RIGHT AND SEE IF PURITY CHANGES OR BECOMES GOOD.
IF SO A MANUAL COIL CAN BE USED (CALLED A DEGAUSSING COIL) TO CORRECT IT--TAKES 5 SECONDS.
SECOND: SHADOW MASK IN TUBE (SCREEN) IS DISLODGED BY MOVE----THESE ARE VERY HEAVY SETS AND THE MASK IS EASY TO DAMAGE.
The mask is inside the tube and perforated with hundreds of tiny openings that line up with the phospher coating (stripes if you look close at set with it on) if mask got dislodged in move--damage is permanent.
If changing north,south, east or west position of front of set corrects it mask is good.
