1979 Hitachi (NP9X-L chassis)

[Dreamsbeard]

Good afternoon guys,

I picked up this 19'' 1979 Hitachi this morning. At first, all three guns where barely registering on the CRT tester, but after a soft clean and balance they came back to life...and pretty strong also!

I couldn't believe how bright and sharp the picture was! This one is a keeper for sure.

A few things I would like to know : if you look at the third picture , you'll see that in the top of the picture there are white lines, those line slowly disapear when the tv warms up (takes about 2 mins), could those be related to bad caps?

Also, in great contrast scenes (or when there is subtitles) the television emmits a "loud" buzzing sound. No matter of much I calibrate the channel 3, I can't get rid of it. Is there a way to eliminate that buzz?

Thanks!
