The fault should be with its supply voltage to video output section circuit. Check this voltage. Check the smoothing capacitor used there. The video output card stage, can be located at the back [neck] of the picture tube, will directly plugged on to it; and can be pulled back out gently. Take care. http://electronicshelponline.blogspot.com/ Check this link for more details. Pull up older posts.

Try a "hard reset"===unplug AC for a long time, like overnight.Let me know if there is any change.

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

Hi,
I hope your TV model is Sony KV-G21M1 and you see color bars as horizontal lines across the screen.
Let me now are you tech guy or know how to repair TV to guide you further.

The half picture is a verticale problem. This is difficult to repair. Send to a repair shop.

I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,
