about a month ago and now it appears that I may need a new one. The symptoms are slightly different than the last time in that the picture and sound will come on for a few seconds before going blank, then the power light flashes red. The last time it happened I got no picture or sound at all. I removed the lamp and it looked fine to me with no abvious signs of damage, but I can't say I know what to look for. Any thoughts? I have an extended warranty through CC, but only 1 bulb replacement is included in that.
