| Don't disconnect The diode for the circuit that does the feedback.
Try using a lightbulb in series with the P/S if you don't have an autotransformer. Have you checked the low and high value resistors? This is all I can suggest for the moment. |

Konka CTV K3466 
Blows chopper transistor instantly on switch-on. Replaced drive IC and all electros, checked opto on our opto checker, desoldered one end of all diodes and non-electros, checked for leakage and correct values, checked all components in feedback loop. Help! It's driving me nuts! Does anyone have a circuit? |
