Question about Televison & Video
Picture comes on and of..
Posted by Anonymous on
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

Hi, IK circuit is engaging which basically means the picture tube is getting tired, the only "fix" is temporary (may get another year out of it). You have to increase the "screen control clockwise".
Remove back of set, follow large black or red wire attatched to picture tube down to the flyback transformer, mounted on flyback are two black controls, one is focus (leave it alone) the other is "screen", adjust it clockwise approx. 1/4 inch, remember that this is a high voltage circuit so use one hand in the set the other hand out of the set at all times,any questions ? e-mail me back, good luck, BMW Rider

I think that you will find the picture tube to be more expensive than a replacement TV, if it is still available (unlikely). That being said, it is also unlikely that the tube itself is the problem, The more common problem is the horizontal output transistor or the flyback transformer. Either part should still be available for a reasonable cost. Check with a local servicer for the part numbers and costs. These are common parts.
