Question about Televison & Video
It sound to me like a defective light engine. If so this is a very expensive repair if you set not under warranty or a service contract. This could have been damaged by a power surge.

As technology evolves, Sony continually looks to stand behind the reliability of its televisions. It has come to our attention that a very limited number of televisions manufactured between 2003-2005, after a period of time exhibit a stationary scribble / random line pattern on the screen. Click here to see photos of this symptom.
As part of our commitment to quality, Sony is announcing that for any owner of this model television who paid out-of pocket expenses on or before May 26, 2006 for an estimate or repair service to replace the optical block for this specific issue, Sony will reimburse the customer by mail for his/her parts and labor expenses. To receive reimbursement, please follow completely the directions and terms on the claim form for reimbursement; all claims must be postmarked by May 31, 2007.
In addition, for any customer who later experiences this issue on one of the affected models, Sony will cover the cost of the optical block repair at no charge through September 30, 2007. All other terms of the Sony limited warranty continue to apply.

I suspect that your backlight has gone out. If you shine a light on the screen can you see remnants of the picture that should be displaying? If so, it's definitely the backlight, and most likely the power inverter for the backlight. You can probably find a replacement inverter, but you may need a repair manual to install it. I'd recommend checking the warranty status first and sending it in for repair if you can.

At this point there is not much you can do.
If this LCD is less then a year old, I would suggest to contact the manufacturers to get it fix under their warranty.
