SHARP TV 20V-L50 NO TV SIGNAL

This problem or trouble was found by me in an electronics forum here in the Philippines. This Sharp tv model 20V-L50 no tv signal with pale red in screen of tv but no sound. But Audio and Video in with good picture and sound. The culprit a transistor with part number C1815. Thanks to this forum ww.elab.ph/forum/index.php?topic=22517.0;nowap and to simatar the technician for posting and sharing this found trouble of this tv. Here is the picture below.





I found this while i searching for schematic of same tv model and in this forum i was member also. I post this to help others too with same problem. Hope it helps.
