SOURCE: SONY KV-27FV310: UPPER HALF OF SCREEN IS BLACK

You have a vert sweep problem and unless you know how to trouble shoot this cuircit bring it to a pro. I found out mostly in these sets that the vert output IC is bad.. Also sometimes the b+ filter cap off the fly is leaky and made the IC to fail. Another thing is Im surprised to hear you got a pic with the vert failure and a bright line in the pic!! This could be a big problem when the sets fixed so dont run it too long like this. It could burn a line all the way across the screen and you will see a dark faint line in your pic because of this. BE CAREFULL!!

SOURCE: tv problems

It's called a loss of vertical deflection. In this particular model your set uses a TDA8172 for a vertical Ic, at board position Ic561.
Replacing that and check or replace the feed cap out in front as needed should restore full deflection. It's not an expensive fix for a qualified shop either.. But my advice is take it into them and save the pu/del charges. And call around to see if they have the Ic on-hand and about how much it will be to replace it before choosing the shop to take it to..
Let me know how it goes!

Sony Trinitron kv-27HFR blurry


the picture tube is gone.
i repaired 150 sony xbr and kv series with that problem.sony has a single gun not three and has a great pix,but burn out faster.
there is a main screen control that you can adjust ,but the tube is gone.
on the back of the crt there is 3 gun drives r g b .
turn the color all the way down so it is black and white.
if there is a green ore purple tint,one gun is out of balance.
ajdusting the r g b controls so that black and white is normal is what you want to do.
the crt board has the screen bias voltage 800volts on it so be very careful and use an insulated screwdriver to adjust the drive controls.

Sony Trinitron picture turning green hues


Nowadays CRT's do not have good quality shadow masks anymore. After heating up a little they can give a so called "blooming" effect giving a blue an yellow leaf effect large over the screen. Reason nonparallelity in deformation of the shadow mask.

KV-32FS120 makes a loud noise and green tint when turned on


Loud noise is possibly made by Degausing Coil to demagnetize picture tube and its normal.
Green tint shows picture tube is bit weak in electron emission due to its age and takes time to present good white balance result (good colors)
