I have replaced alot of these light engines for this problem. Yesterday I received a letter from Sony saying they are going to give an additional warranty to have the optics replaced. I just checked, your model is one of them and Sony is replacing the optic block under an extended warranty, regardless of the purchase date, until the end of October 2008. Contact Sony for an Authorized Service Center in your area or go to this site to read about it: http://esupport.sony.com/perl/news-item.pl?news_id=185&mdl=KDSR60XBR1 Have this repair done on your set and it should save you about $1300.00 to $1500.00 on the repair. Hope this helps.

Your problem is very lightly to be A faulty invertor pcb.
Relatively easy to replace but you may find it difficult to purchase.
The invertor pcb basically makes high voltage to strike up the tube lights behind the screen.
What make & model is your tv set & what country are you in.

Your problem here has to do with the amount of aging that happens to the three colour tubes - red, green and blue.
Blue actually ages slower than red and green. What actually happens is the green tube deteriorates and due to green being the predominant colour for brightness causes the blue tube`s flyback lines to appear - especially when switching between inputs or when the video is blanked.
No replacing the blue tube will not solve your problem as the tube is actually the best one of the three.
As someone mentioned there is a way to adjust this by removing the speaker grill assembly in front of the set. Doing the service mode adjustment with the remote is not the right way to solve the problem - you would be adjusting the colour gain and off-set values and would seriously be compromising the white balance of the set.
On the left hand side behind the speaker cover you will see a black square block with six adjustment points. Look for the one marked SCR BLUE, Switch the set to a unused input so the blue lines become visible. Now adjust the BLUE point counter clockwise until the lines disappear. A small adjustment should do it, Switch back to a picture and make sure the whites are still white.
This should sort your problem. I would however suggest asking a Sony service centre to do this for you. This is a dangerous thing to do as you will be working close to the 35Kv supply the the anodes of the three tubes.
I hope this answers your question.

I have a 37"Samsung LCD and having just spoken to the Sky engineer (also a friend) he says it is a national problem between Sky+ and Samsung. I have the same problem when on playback but not on real time? If you had your box changed to an Amstrad what sort did you have the problem with?

There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.
