Hi: My KDS-50A2000 projection tv turns on for a few seconds to one minute and then turn off by itself. The power LED start blinking 9 times then stop and starts with the 9 times blinking again. I checked the power and it is at 120VAC at the receptacle. I can see that two fans in the back are spinning while the tv is on and then stop when the tv turns off by itself. How many fans do this tv has in the back? Some people mentined three but I can only see two, one close to the lamp and another almost in the middle of the back cover. Any help on this problem will be appreciated. Thanks. Best Regards.
