This set squeals when AC is applied. It will try to turn on if power button is pushed but will do the three time try then go back to the squeal. Horz output is good all caps in power supply are good checked all diodes in power supply. I removed collector on horz out and still squeals with it out of the circuit. Need a few other tips if anyone has any. There where no squealing tips on the web site.
