This set when powered up,high voltage comes up to 25kv for just a few sec.and then shutsdn.I varied the screen voltage to see if it would stay on but did not.I removed the crt bd but also no diff.I resoldered alot of cold solders around the flyback and horiz.drive ckts and still shutsdn.I am think that eighter the vertical ic tda-8172(not in stock) is shutting it dn or the flyback is bad.Trying to find my manual (moved to a new location) but still mia.If anyone has any tips or idea's on this shutdn problem,please advice.
