When JVC send you a replacement bulb by fed-ex, do they pick up the old bulb. I took mine out on Saturday, and my wife was nice enough to through it out when I was at work Sunday.
When you called, did they ask for a credit card number?
Addtionally, (Note not all sections may apply to you:-)
POST 1: The mfg /model 2: Serial number of your set 3: Date of mfg 4: Date of purchase 5: Note symptoms in DETAIL 6: Note hours run each day, 6a:Note estimated TOTAL amount of run time. 7: Note amount time set say on once it is powered up. (In other words your not turning OFF and back on every time a commercial comes on.) 5: Note if set in plugged into a UPS -to not only FILTER incoming power, but to PROTECT set from BROWN-OUT conditions (low voltage)
Posting details like the above not only will "help" JVC address the problem... but it will make it ALLOT harder for them to "wiggle" out of any claims, lawsuits that may come about if these issues are not fixed.
