|
|
On light background there are horizontal lines, looking like scanlines, never seen before; The lines ore not evident from seat position, but if you go near the screen (from about 5'), they are very obvious. They are present both on video files and Marquee calibration patterns and in each color (obviously in green they are more apparent). I tried swapping VIM board and Control board, with no success..
Any idea?
Thanks

Try re-seating the horizontal, plus re-seating the daughter board,
See if that fixes the issue.

Thanks Steve, I've swapped HDM board with a spare one and lines disappeared.
BTW this HDM requires a much lower width to fill the screen (and so the tubes): from 95 to about 75. Don't know why, but anyway it works, just little more ringing on the left size...
The other HDM, even after re-seating and re-seating the daughter board has the same issue... There something wrong with it...

Probably needs a re cap, those lines look like the noise I had from My Astig amp.

The width is probably due to the adjustment coils, the 6 white tubes.
3 are for low band, 3 for high band.
I have never played with them, BUT if you do, use a plastic hex tool. NO METAL.
