See subject! Toshiba TV shuts off after 1 minute of turning on with the red light flashing. There is some semblence of a picture if I mess with the rbg setting underneath the speaker cover, but just outlines. It will stay powered for ~ 1 minute, then shut down. Any help? Should I replace the convergence IC?
Easy to fix. I have fixed this porblem before i do 3 to 4 tv a week and this problem happens all the time. There is a loader chip on the main circuit, Just replace this and you have fixed it.
This does not sound to me like a convergence roblem. It could be a shorted picture tube. That would put the set in a shutdown condition. Normally in Toshibas , the picture remains on with a convergence problem. Here is something you can try, but you must be very careful. Remove one crt board at a time from all three tubes. if the set stays on after one of the crt board are removed , then that is the shorted picture tube.I cannot caution you on how care full you have to be trying this procedure.
