how can i fix my dlp projection sony tv model kdsr50xbr1?
when i turn the tv on it immediately turns off and the red light blinks 4 times. I have unplugged the power cord for several minutes and hours and no change. It happened several weeks ago and when i vaccumed the dust out around the two fans in rear of tv it worked for about three weeks but hasn't worked this time. Help Please.
