This unit came in with reduced vertical height, NO picture NO audio. Has OSD. Vertical height only about 8 inches with completely black raster. Can run screen control up and have raster. Can hear buzz in audio when OSD is up. Voltages in power supply and horizontal are close. The voltage on SCR501 are: A= 6.8vdc G=0.2 C=0 however the voltage on pin 1 of U4501 is 6.1 Replaced CR4504 and C4520. I have worked on the CTC169 many times however this one is costing me time. Any help will be appreciated.
