I have a F38310, JX4, purchased about 3 1/2 years ago. Had it serviced under warranty within a couple of months to correct "geometry" issues; I think the capacitors were replaced but never have verified. The unit was ISF calibrated a few months later. Everything has been great.
A week or so ago "horizontal lines" appeared on the screen (retrace?). They are white and vary in number from 8 with standard defintion to 16 with high def material. They are most visible in dark scenes and can be hidden in bright scenes, particuarly HD. The lines also have an "hourglass" starting pattern at the right and left edges. These lines appear on all forms of input; DSS, off air - both SD & HD, component inputs, progressive directly out from the DVD and scaled through a Lumagen to 1080i.
So a few questions.
Is this scenario one of the ones reported with the DM-1-capacitor-diode issue?
Does anyone have a document aiding a DYI effort to replace the capacitors & disodes including parts type/value ?
Does anyone know of a reliable tech in the Portland, OR, area? I can't remember nor find any doc's on the original service call. It appears the a company "Sharper Video" is both a certified RCA service center and ISF certified. Anyone with any experience with them?
Thanks in advance for any help..
