Question about Sony FD Trinitron WEGA KV-27FS100 27" TV
While watching a TV show on my Sony Trinitron, the picture will disappear (screen goes black), but I have sound. If I turn the tv off/on, the picture will come back, but later it will turn back to black.
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
