I've had this set for almost 4 years now and since i moved from NY to TX I've noticed ta couple of tiny blue dots on the screen. Also, the right lower corner of the screen a blue color which seem to be getting larger. and lastly a larger spot with a greenish, blueish color toward the lower center of the screen. Is this a bulb problem or something more serious? I am fairly handy and I was wondiering if its something I could handle. Any help would be greatly appreciated.
My picture is gradually fading to black. It started in the upper corners and now I have shadows pretty much all over the screen. My Sony is only 3 years old. Am I just out of luck or can this be repaired or replaced?

Where has the unit been kept for all that time? I ask this for reasons which will become obvious to us both, once I know. If it's been stored in a dry, dust-free environment, and not moved and/or knocked about, then the problem can be sorted by people I know with more knowledge than me. However, if it's been stored in the open or just covered with a cloth or the like, then the problem is probably damp/dust/knocks/moves. All of which are not good for the unit in storage.
Please reply with relevant storage details and I'll get you help you need to get it working again.
Actually its pretty funny thing with those speakers is the "fuse" is Actually called a Lamp in this case. These are what they call a " Red Dot Fuse ". in all the years i've been doing this i've never thought to look up the value haha. Just have to know there are Red Dot lamps and Blue dots and No Dot. If you examine the LAMP you should see somewhere close to the ends ON THE GLASS a color dot of some kind. almost like someone painted it on there. Red Dot Lamp. any parts distributer for people like Harbinger, Peavey, and B52 will KNOW what your talking about
I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.
if you see blue pixel type groups of squares or dots you may have a burnt light engine and this is common in many LCD rear projection sets; a blue screen may mean the engine became burnt--LCD rear projection sets of this kind have an optical enginge--with red,green,blue prizims--sometimes they get burned by the lamp---a photo would tell me or most techs what the problem is---the cost of a replacement engine is very expensive--some models with this problem are covered by Sony even if the set is no longer in warrant
This set has no internal manual adjustments for color. The Tracking or B&W balance is accessed via the service menu. I don't suggest you attempt to adjust without instrumentation. the trouble with your set is not an adjustment. Most likely the Optics are at fault. This model has had issues with filters in the optics being destroyed over time by the lamp. The blue haze will get worse and continue to grow over the whole picture. The only option is to remove the Optics (light engine) and sent it out to be rebuilt.
