Could be an easy fix, soldering the pins on the vertical IC (IC501 I think)may fix it. also check the standup board pins being loose/dirty on the left rear (if yours has one). best quick test is bang on the set and see if the top half comes back for a second, if it does you have bad connections, an easy fix if you can solder.
thanks

I have a Sony FD Trinitron 27' Model # KV-27FV310. It is approx 8 years old. After turning it on and watching a full screen for a few minutes; all of a sudden, a line came across half the screen;


top half missing is in vertical circuit of set---if it is a 27 inch and this old consider retiring it and replacing----other option is consider having a shop repair it--a rough guess would be as high as 150 dollars parts and labor is possible for your problems.

Sounds like a problem with the vertical circuit. If yuo can solder and are comfortable with working inside the set, you may be able to repair this.

Keep us posted.

Cannot see TV through digital box on my sony trinitron


If there is no audio as well then this suggest that the digital box is at fault. The fact that you can watch DVD's proves this fact. Unplug the digital box for 2 minutes and then re-try. Good luck.

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!!
