Hi everyone

This sony tv model  KP-43HT20 , and chassis RA6 has very faint uneven 
horizontal bands on the screen fro top to bottom which is most 
noticeable on the red. When red crt covered, bands  goes away and when 
blue and green covered bands are very noticeable.I tried to lower screen 
voltage on red but those bands are there as long as you see any red at 
all.These bands are about 2 mm thick and uneven . Please note that these 
bands are not retrace lines.Any help or suggestions would be appriciated.
