Question about JVC AV-27720 27" TV
Have a blue shadow on piture also on convergance screen...blue is three times wider than red or green. tried to adjust manually and would not adjust out. A couple days after tring to adjust convergance it really went bad and the convergance problem changed to wavy horz. red, green ,blue across screen. I replaced converg. chips ,purchaced from panasonic. This took care of wavy effect across screen...however the blue shadow (orignal problem) is still there. Cleaned lens on all guns, fluid seems to look clear. Tried to adjust blue gun by rotating it as to focus it...no luck, would not correct or sharpen blue. I also ohmed out the resistors on the converg. bd. while I had it out..no real out of spec. resistance from marking on resister. They were very close. Is it possible to swap leds on converg. bd ( exple: green for blue gun)to see if problem moves to green, or stays with blue gun? Or is there a service menu to adjust this? Thanks for your time! Gmann
