Question about Sony Grand WEGA KF60WE610 60" Rear Projection Television
If they look white or like pixels out this model is prone to a bad optical light engine---it is the heart of the set and most expensive part as well--typically it starts with one or two and over time more "appear".

The problem might be with the circuitry driving the LCD screen. Since the back lighting blub has been changed the only thing that could cause this issue would be the screen brightness which is controlled by the LCD circuitry. You will need the schematic to aid you in the measuring of these voltage values.

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.

It most likely is the optical block that needs to be replaced. Sony knows that these tvs are having a problem with this so it is possibly covered by them depending on how new it is and whether they say that this is a known problem for this specific tv. I would first give Sony a call at 800-488-7669 to discuss this issue and see if they will fix it for free otherwise replacing the optical block yourself is the best solution and you can order the part from Sony too through that number.
Let me know if you have any further questions and I would be glad to help.
good luck with this

It sounds like you possibly have a bad optics block. If thats the case it is not a user replaceable part due to the tear down to get to it. Is there anyway you can email me a picture of the television with the symptom and I can possibly help from there? My email address is tvtek(at)msn.com
