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

SONY KV-27FV310: UPPER HALF OF SCREEN IS BLACK. Bottom half of the screen is normal. There is a white bright 1/2 inch horizontal line (just in the middle of the screen) that separate black upper half and normal bottom half. This TV was bought in 2003.

    My problem is the same as vova's - the top half of the screen is black, the bottom half is perfect and there's a white line between the two. I called the cable company and they said it's the tv and not the cable box. It's Saturday night so I have to wait until Monday to do anything.

    Ya same problem here... did either of you two get it fixed or did you just end up buying a new one?

  • cdiesse Jul 05, 2008

    yes ! Same problem here ... I think Sony have pre programmed his TV trinitron tube to die after 3 years ... Hope there is a solution, but I don't trust Sony anymore for long life material.

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!!

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.

Sony TV - Loss of half the picture


sarge, it sounds like the vertical output IC went bad on you. If it was a bad connection or a bad capacitor, your picture would have been a straght line across the screen. They call the output section of the IC a push-pull type of amp, so the top half of the sweep IC went out. If you have had some soldering experience, and or experience with solid state repair, locating the bad IC and replacing it is no big deal. If you havent, stay safe and call in a pro to assist you in this repair, as there is alot of high voltage inside this puppy that is still present even if the set is unplugged. It should not cost an arm or a leg to repair this set. An honest repair on a set like this if you take it in should not exced 125 to 150 bucks. Good Luck PS Please dont forget to rate this thread.

Top half of screen black


The vertical circuit is going bad,this is the one in charge of opening the picture up and down,try taping on the side to see if the picture reacts ,if it does your set has a loose conection and the vertical IC will need to be resoldered only but if it does not react the IC will have to be replaced,if you are familiar with tv service this will give you a place to start but if you are not be safe and seek the help of a servicer,please let Us know how it goes.

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
