Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
After numerous efforts to repair I still have three blinks and squeal is gone. The following parts have been replaced: CP114, CP120, CP130, flyback 259296, HOT C5588, DL201, CP049, CP050, CP019, CP012, CP113 and RP050. CP150, DL012, CP010 were removed and checked OK. Voltage at BP010 was about 330vDC. HV wire from flyback removed at splitter with no change. BA010 removed with no change. I recently asked a question about whether is a red LED when set is in standby because I am going back to the beginning of the troubleshooting and service manuals. I am a novice and I am enjoying this experience in solving this puzzle. Thank you in advance for any help.
My sony did the same thing and worked fine after replacing the bulb. A pop sounds followed by a squeal is what I heard during and after the bulb blowing out. I hope this helps. And the red light flashed similarly.

So Far You've Done Very Good, The Horiz Output Is Located Very Near Or On The Flyblack Panel, It 's Usually A Rectangular Transistor Mounted To A Very Large Silver Like Heat Sink ..It Does Sound Like It's Shorted, But If Not,Check The Focus Divider Or Hv Tripler..
