If rattle occurs please perform one, or all, of the following if necessary. 1. Check if the Sony Emblems is loose. If so please perform the following: a. Carefully remove the Sony Emblem b. Apply glue (Sony Bond 7-432-912-52) to the Emblem and re attach to the Bezel. 2. Check to see if the grommet attached to the speakers is loose around the speaker mounting post. If so please perform the following: Reference: T. Tomura PRINTED IN USA Autoflagged - NO PRINTED ON RECYCLED PAPER TV Products Service Bulletin No. 244R1 b. Allow for 12 hours of drying. c. If this fails to resolve the speaker rattle then replace the speakers as follows: Part Number of Speaker: KV-27TS xx or 32TS xx: 1-544-549-11, KV-27S xx or 32S xx: 1-504-531-11 3. Check the cabinet for vibration at the junction of the Bezel and Rear Cabinet. If this should occur please perform the following: a. Apply tape, 7-632-661-51, around the Rear cabinet making sure it will not show when the cabinets are re attached. b. Apply tape to the inside of the Bezel where the CRT touches the Bezel if rattling should occur. c. On the 32 inch Bezel, it is possible to insert double sided tape from the front of the unit by placing a finger above the Sony emblem between the Bezel and CRT.
