Question about Zenith IQC50H94W 50" Rear Projection Television
Turned on my set that had just been working fine and there is no picture or sound. Slight Electrical odor when turned on. Also a "chirping sound about once a second. LED DP37 blinks in unison with the chirping sound. What broke??
It sounds like a defect in the horizontal drive or HI voltage circuit. Could be the Horizontal output transistor , and /or the flyback transformer, a short in the scan derived power supply on the output of the flyback transformer. If your not aware of the HI VOLTAGE issues and have soldering experience you should seek a pro to assist ya in this repair. If you do have the experience, get a schematic and start with the hi voltage circuit. Good Luck
