Question about LG RU-44SZ51D 44" Rear Projection HDTV-Ready Television

Blue dots my tv is now 26 months old...after 18 months of faultless operation several blue, pin-head sized dots appeared in a cluster on the bottom of the screen. It soon grew to a 30 plus cluster over the next two months. it's now grown to three clusters of over 100 dots along the bottom of the screen with several scattered smaller clusters (approx 10 -20 dots) around the rest of the screen. through the dots we can see that the remainer of the picture is a sharp as it ever was. we occasionally get a pale blue "water mark" on the screen. nothing consistant in either size, shape or position on the screen...while not ideal we can live with this if we have too

You have a bad blue LCD in the light engine. Replacement of the light engine is the only fix and it usually will continue to get worse over time

Blue streaks might have been just your video connection and problem with signaling. But, blue dots is faulty light engine, aka "optical block". The engine in this could be a defective LCD array. Very expensive, a optical block is about $850. Hope it's still under warranty. You could get a rebuilt one, possibly. Need service adjustment too. Bad problem that Sony has with these kinds of sets.

Near the bottom edge of the screen on my Wega KF-50WE 610 has appeared a ''blue haze'' that appears after the TV has warmed up. It started a few days ago as ''fuzzy blue dots'' about the size of silver...

This was caused by a defect in the optical block of the TV. It will only get worse with time and the only way to fix it is to replace the whole optical block which is very expensive (over $1000 usually) and time consuming (you need to take the whole TV apart). However, since it was a defect, there was a class action lawsuit that caused Sony to extended the warranties for certain models on the optical block for parts and labor. Call Sony to see if your model was one of the ones they extended the warranty for.

Blue dots in KDF-60WF655

Yes, your optical block ( light engine) is bad. Heat generated by the lamp circuit with its poorly designed ventilation system, cause the LCD panels inside the light engine to fail. They are the size of a postage stamp. There are 3 LCDs, for red, blue, and green. The heat causes them to warp and de-laminate.

Sony has systematically downed played the scope of this issue. It appears however that virtually every LCD projector they make can develop damage in the light engine which is extremely expensive to fix.

I suggest contacting Sony and your state's attorney general's office of consumer complaints asking for action on this.

HDTV is getting blue dots and the right side has turned blue

These issues are problems in the light engine (optics block)
the dots are called "starfield" and the geometric is "roadmap"
replacing the light engine will fix the issue. for awhile, sony was extending the warrany on the engine for these issues only, but that may have expired.

LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck
