I bought this TV not working, I thought I could learn a bit by trying to fix it. I replaced a couple of boards and I can get it to display the top half of the picture but I don't want to spend any more money fixing it, I already spent too much. Just trying to recoup my losses a bit by selling it (also can't bear to throw an almost working tv out)

Hello!I bought 12 years ago a SONY TV KV-28FX60D with out any technical issue so far.The last couple of days I powered on and after five minutes it starts showing only half of the screen, losing the bottom half of the picture. what do you think it might be. Can you suggest a part to be replaced and if it is worth fixing, cost wise? Thanks KONSTANTINOS
it sounds like one of your buffer boards are going bad. these are the boards that help put the picture on the screen. there are 2 boards an upper and a lower board. if you remove one and turn the tv on you will get half a screen. see then if you get the lines. please leave rating after you check.
If you talking about on one screen, you cant. BUT you can buy a TV card for your computer so that it will have a built in TV. so you can theoretically have split screen TV and computer. But what your thinking off only works on 2 or more player games consoles
If the screen split is exactly 50/50 top/bottom You are not getting SU or Scan Upper drive. These are lovely set to work on. Most likely is SU board itself - Not repairable just to be replaced. Sorry I work in the UK so I can only guide that the UK part is around £30 SU may have been damaged by failure if the PDP (Plasma Display Panel) but is 9 years only had 2 screens damage the SU board. There are several setups to do after fitting a PDP. If you don't have the service data - Do not risk it, Reduced life of the Panel and a safety risk.
It is not clear where you say input is from cable, do you mean the Scart input to your Sony TV?
Do not use Progressive scan(p), as this is not interlaced. The normal TV requires an interlaced(i) picture of 50 half frames per second giving 25 complete pictures per second to reduce flicker.
Some TVs and projectors and all monitors accept Progressive scan.
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
