 Posted: Thu Nov 24, 2005 7:08 am Post subject: RCA CTC203CX - no video (no picture) but has menu and sound |
 |
|
RCA TV F32665 has raster and menu appears on screen and works perfectly fine, sound is ok, but NO video (i.e. no picture). Air/cable channels can be switched - sound always comes in, but no picture. Same result when using the video IN (e.g. a DVD source). Obviously a video-path issue.
This appears to be a very common problem for RCA chassis # CTC203CX also ATC113CA1 etc. Found many similar posts on the web/forums, yet no solution.
Please post any specific tips or remedies that you know of. EURAS seems to have the answers, but is paid-only access. Thank you |

| If I'm thinking of the right chasis, check the I/O board and associated panel to panel connections. |

| pls find the tuner and look the b+ and use tester and calculate the b+ plus of tuner. if there is no output votage look a resistor or fusable risitor and re soldering the b plus of tuner. |

I suspected that too. Forgot to mention that I already eliminated (plugged-out) the I/O board altogether and disconnected the PIP module as well. Still, the problem persisted for the air/cable channels… |

Vertical?? - That's not the case here. As I mentioned, the OSD (on screen menu) and raster appear perfectly fine... |

"cambien el regulador de la placa de video input esta no se encuentra
con su voltaje adecuado" como vemos es una pueta de control para las diferentes entradas de video por "Camatron"
