No not fatal, but sick. this problem you are having sounds like you have a vertical sweep problem.. It could be the vertical output IC, the sweep power supply or a capacitor or two is bad. If you have printed circuit board soldering experience, you can try and fix this yourself, but if you do not, play it safe and call in a pro to assist you in this repair as it should not cost more then 100 bucks to repair. Good Luck

Line across middle of screen, rest of screen black


The problelm is a defective vertical deflection system. Could be the amplifier, vertical output driver or whole printed board that supports the vertical deflection activity. It is considered to be a serious failure.
The cost of repair will be around $200 to $300.

Screen is black except for thin line in middle of screen


The problem is in the vertical section of the main board. Bad capacitors and maybe the vertical IC. If you are not inclined to be a tech you will have to take it to a shop.. I don't know what they may charge but I normally get $69- $89

I have a sharp aquos 52" with a thin vertical red line in center


If you have a thin line running down the screen, you may be looking at a service issue right off of the bat. Here is a few things I want you to try before calling sharp, 1. Reset the unit from the setup menu
2. Unplug the unit for 2 minutes then plug back in. If that does not work. Take digital pictures of the line and call sharp immediately. Make sure you tell the rep you want to sign up for the aquos advantage program that they have(extends your warranty 3 months free of charge!) because that will get you priority service on with your issue. If they cant resolve that line ,9 times out of 10 they will replace the unit. hope this helps you

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace. You'll need to take your set to service center to have it serviced.

Good Luck!
