KV-36hs20 My Dad bought a KV-36HS20 about 4-5 years ago from Audio King. He purchased cheap from them because it was returned(I know, big misktake). Ever since he purchased the TV, there would be a pop or crack sound followed by a green horizontal line flashing across the screen. The flash occurs more frequently the longer the TV is on. It disappears after a second.

You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.

SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

I have this set also..
When you set up for an HD signal (1080i) it is broadcast in 16:9 which is a widescreen format. The Sony set is a 4:3 format (more of a square shape) which means the black bars at the top and bottom appear so that you get the widescreen 16:9 format to appear.

This is one of the main negatives I have about this set, however, I can't really complain as I have had it for 6 years and it works great.

I never knew about the other format until I got an HD receiver from my satellite dish provider last year.
Hope that helps explain it for you..

Have you tried disabling SVM (scan velocity modulation)? Often touted as a "feature" of TVs, it's a way of artificially making a picture appear sharp. Totally unnecessary. When SVM (sometimes called VM) is on, it can lead to some color bleeding around edges.

Have just posted this - twice, elsewhere - I'm afraid the sets are getting old:
"I think you are either suffering from a failed power supply or the supply is cycling because of a 'downstream' problem that could be in the high voltage circuit. In each case, the blink count probably would tell you approximately where the problem is located but only a Sony tech will have access to the codes. After all, we are only mortals.  "
