I have a dead Toshiba TV, model CX3583A, chassis # TAC 9191. I have been trying to locate a service manual for the last several months with no success. When the set is plugged in, a relay on the power supply repeatly clicks and the set will not turn on. Since I have not been able to locate a service manual for this set, I have not attemped any repairs yet. Has anyone run into this issue, or are aware of any problems on these sets that can steer me in the right direction? Any help or information on where I can pick up a service manual would be greatly appreaciated. Thanks!
jir: Initially, based on the symptoms you reported, look for shorted, open or faulty components in the areas of the power supply and deflection circuitry. The service manual has no in depth troubleshooting or component testing proceedures... these kinds of things are what a knowledgeable and experienced tech is trained to do... with the necessary test equipment and proper replacement parts. A service manual will do little good unless you are able to perform some basic troubleshooting without it.
If you are not certain how to proceed with the initial and basic troubleshooting and testing you should go to the website for this newsgroup at:

there, with some searching, you will find a wealth of troubleshooting tips, repair proceedures, component testing methods, and important safety information that will help you to stay away from dangerous and lethal electrical shock hazards inside your television.... note that even when the television is unplugged from the AC power that these hazards may still be present... be very careful. If after reading over the repairfaq, you are still not able to perform the initial troubleshooting and testing you might be best advised to TAKE your television to a service shop for, at the very least, a repair cost estimate so you can make an intelligent repair decision with facts instead of guesses. electricitym
