This Zenith B27A11Z would chirp at plug in,but push power and hear the HV come up with instant shut down.Inspection underneath found a cracked trace from the first flyback pin over to diode DX2104 anode. This removed voltage from this diode killing vertical, hence shutdown. Bridged trace,fixed. -- Philip Bader, Jan Phyl TV Inc. 3420 Recker Hwy,Winter Haven, Fl. 33880 voice/fax: 863-299-8821 Established 1976 ------------------------------------------ To REMOVE your email address, click here: http://www.tech-assist.org/unsubb.html To CHANGE your email address, click here: http://www.tech-assist.org/change.html ------------------------------------------ ***NEW*** Tips Added Instantly!!!*** Submit Repair Tips here: http://www.tech-assist.org/secure/tip/
