Zenith TV troubleshooting question
I do realize that a TV is not a computer but I am hoping the smart people here can help me. The wider internet has not been very helpful. I found a 20" CRT Zenith today, model #SR2053S. Yes it is ghetto, yes I should just get a real TV. However imagined for a second that you wanted to make this POS change from the AUX channel on which it is stubbornly stuck. What would you do?

Re: Zenith TV troubleshooting question
Assuming the TV has a button on a front panel, you could try and remove the panel and manually short the wires or circuit or whatever that button presses against.
Danger, messing with electricity might kill you. |

Re: Zenith TV troubleshooting question
First gotta get it outta the way:
Eh? There isn't a front control panel you can manually control it from? Second: Have you tried a remote (universal obviously) Third: Thats probably why it was tossed if you "found" it [img]/images/graemlins/smile.gif[/img] |

[/ QUOTE ] Pressing the buttons on the front control panel makes the screen flicker like it does when the channel changes (so I don't think the contacts are faulty) but the channel doesn't actually change from AUX. [ QUOTE ] Second: Have you tried a remote (universal obviously) [/ QUOTE ] Yes; my universal remote works fine for power/volume but auto-switches to the cable box when I press the channel buttons. [ QUOTE ] Third: Thats probably why it was tossed if you "found" it [img]/images/graemlins/smile.gif[/img] [/ QUOTE ] Yeah, true. There was a note on it saying it worked fine but maybe they just meant "...for a 10yo CRT." |

Re: Zenith TV troubleshooting question
If the contacts aren't faulty, then whatever circuit board those contacts connect to is probably fried or there may be a short somewhere. No easy fixes, that's for sure.

[/ QUOTE ] I gave up too soon. All it took was pressing the TV/VCR button on the universal remote. This flipped the TV to CH 2, and this let me do a channel auto-search. This found CH 3, so cable works just fine now. Sorry for bugging you guys, thanks for the help. |

Re: Zenith TV troubleshooting question
I still say it is fried.
Recommend completely taking apart the TV and manually resoldering all connections and fault checking with a multimeter. May have to visit local dump for similar Zenith TV models for replacement capacitors, transistors, and various other parts. |
