It's most likely the light engine. Sony has a service bulletin on these right now for one of the causes of this. Both causes result in the replacement of the light engine but they are only covering one type.

Check and replace your component cable wire (Red,Green,Blue). This is a very common problem with these component cables

Authorized sony repair center told me the problem was the Q Box. Ever heard of this? Part runs about 300 bucks. TV is out of warrenty as it is 2 years old. Do you think it is worth it to fight sony and get them to replace the part or just fix the TV?

Part Number is A1167541A, service rep called it a Q Box in the diag, however the web says its the b block assmy.

read this if you think it's the same problem

It sounds like to me you have a bad Optical Block. It is a expensive repair and you may want to call Sony at 1800-222-SONY and see if the would assist you in repairs. Due to the age of it, they would probably only cover a partial amount of the repair.
Hope this helps,

No colour in bottom right corner


I believ you have an issue with the optical block on your set. Light produced by a high-intensity projection lamp enters the optical block and is split into three paths (one each for red, green, and blue) by a series of lenses, condensers, mirrors, filters, and/or beam splitters. Each color has an LCD assembly with polarizing filters and a liquid crystal microdisplay panel (approximately 1" across). On Sony's "3LCD" models, the light is transmitted through each LCD panel, and, on their "SXRD" (Silicon X-tal Reflective Display) models, the light is reflected off each SXRD panel. Finally, the three separately colored images are combined with a special prism into the final full-color image, which is then projected/enlarged onto the back of the screen by a projection lens.
The following annotated photo shows various parts on the optical block of a 2004 3LCD model KDF-55WF655 (note that the LCD panel cover has been removed):

Either the block is starting to wear out or you have something blocking the lens, such a dirt or something has fallen and is blocking the lens

a color dot is usually a bad light engine, you probably need to replae it, you can try taking it apart and cleaning all the dust out of it, this works sometimes.

optical block bad please mark post as fixya!

2003-2004 Model Year Grand WEGA Televisions:

Models: KF-42WE610, KF-50WE610, KF-60WE610, KDF-70XBR950, KDF-60XBR950, KDF-42WE655, KDF-50WE655, KDF-55WF655, KDF-60WF655, KDF-55XS955, KDF-60XS955, KF-42WE620, and KF-50WE620.

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.

You have a bad light engine or in Sony TV sets, it is called an Optic Unit Block Assembly. This is a very expensive part and should not be attempted to be replaced by a novice. Call an authorized Sony repair place to have this repaired. Good Luck
