Question about Sony KP-53V75 53" Rear Projection Television
There are no loose connections, and the collector side of the horizontal output is 75v and then back to 0 volts. Any suggestions?
Never measure the collector of the horizontal output transistor. When the set is on that voltage is spiking upwards of 1000 volts and could seriously damage the meter and possibly shock you. Measure the B+ pin on the flyback instead, it should be 135 volts. Usually what I find is that the flyback itself is shorted, so when you turn the set on the B+ comes up and the horizontal output starts conducting, but the computer senses the extra current in the flyback and shuts the set back off. The red timer light on the front of the set will then blink a certain number of times to indicate exactly why the set has shut down. If you do not have experience analyzing the Sony shutdown circuit then have a qualified tech handle it for you.
