You can't run the set w/the IC pulled. It will go right into shut down because of loss of vertical deflection. |

I have took out the Vertical IC & was checking but still even the vertical Ic is out the Tv is still shutting down.It was supposed to stay on with horizontal line on screen but it's shutting down, so give me some idea on why it is shutting down & goes to standby ( on timer ) |

It may shut down if no vertical feedback pulses to prevent damage. Removing the i.c so would still produce the same symptoms as a fault in the vertical circuit. |

after replacing capacitor... change your vert. ic...and its ok..... capacitor is the main cause of defective ic... aside from overvoltage input... |

Hi , thanks for the idea. I have changed 100uf / 35v , also the 1000uf/25v & 1000uf/35v capacitors around the IC but nothing changed it's still shutting down showing the horizontal line. I want to change the vertical IC and the Tv will work ok & it will not shut down but the problem is after 3-4 days it will have the same problem, so before i change the vertical IC , I have to solve the problem of shutting down, so give me any ideas plz why the Tv is shutting down ? so help |
