I bought a Sony 3 LCD Projection TV - KDF-50E3000 in November of 2007. I noticed this problem a couple months ago, but went away till a few days ago. My problem is that when watching the TV, the TV will all of a sudden turn off, while the green LED light in front flashes approx 67 times (instead of staying on constant) and then turn back on. The red LED "Lamp" light NEVER turns on, so I dont know if its the lamp even though it is over 2 yrs old and has about 7000 hrs on it. I noticed that if I turn the TV on for the first time that day, it will say on with no problems for about an hour or so, but after that hour it repeats the off and on process about every 2 min or so. Its now been happening for frequently as the days go on. Also when the TV starts back up the screen/lighting faintly flickers for a few seconds then is at the normal picture. I thought it might have something to do with my Directv HDDVR (HR21-100) because it has been freezing and sometimes even rebooting itself every so often, but I dont think that would cause the problem. (BTW its connected via HDMI from DTV HD DVR to the TV.) Its very frustrating because I cant watch anything without being interrupted and the TV is only a couple yrs old. I contacted Sony tech support, but they want me to get a licensed Sony technician to come look at it, which is $100 just for a service call, and dont want him/her to come out just to tell me the lamp needs replaced! Could someone please help my on this issue, to avoid a 100 dollar service call. Thanks in advance for your feedback!
