Question about Sony KV-20S40 20" TV
I have this tv about 8 years now. Just recently when I turn the set on it might be Ok for a minute or two and then the picture starts fluttering. It appears it's having trouble maintaining the full image. Then it might go black on the right edge of the screen (1 1/2 inches or so) before it shuts off. The standby light will go and off every few seconds. I'd like to know is this a picture tube problem or a power problem and is this worth repairing? If repairable how much might it cost?
The set most probably has cracked solder joints in one of the deflection circuits, which is pretty common. The picture tube and major components are fine. A good tech can quickly resolder the main board and that should not cost too much. If your set came into my shop I would charge about $50 but ask around, the shops in your area will vary.
