Hello I have a Sharp TV 25AV79 with a vertical collapse problem. Any ideas on a specific fix for this unit? It would be greatly appreciated. --------------------------- Dan Gett: Yes, lots of ideas for a fix.... you need to dust off your test equipment and tools and begin to troubleshoot the vertical deflection circuitry, check for high ESR electrolytics, shorted semiconductors, open resistors, bad vertical output chip, missing flyback derived B+, faulty and cracked solder connections, etc, etc. For lots of troubleshooting tips, repair procedures and component testing methods you might want to visit the website for this newsgroup at http://www.repairfaq.org/ Take some time and read through the repairfaq, taking special notice of the SAFETY information .... there are dangerous and lethal electrical shock hazards inside the television that can still be present even when the television is unplugged.... be very careful. If you are still not certain how to safely proceed and actually perform the necessary troubleshooting then you might be best advised to take your television to a service shop for a proper and safe repair.... or at the very least, get a repair cost estimate so you can make an intelligent repair decision with facts instead of internet guesses. -- Best Regards, Daniel Sofie Electronics Supply & Repair - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - |

Troubleshoot and repair the vertical deflection circuit. Should be a very
easy fix for even the apprentice technician. Dan Gett wrote in message om... Hello I have a Sharp TV 25AV79 with a vertical collapse problem. Any ideas on a specific fix for this unit? It would be greatly appreciated. Thanks, Dan |
