Kf-42610 blue hue and blue dots on screen

I have had this sony TV for about 3.5 years. It has about 100 blue dots on the right side the TV. On the left bottom corner, there is a blue vertical streak that goes half way up the picture and in the middle upper left quadrant is a blue hue like circle. The picture gets worse each day. Any advice? It was a great TV until about 1 month ago.

    I have a KF-42WE610 it has a blue half moon shape that gives everything a blue tint. I have replaced the bulb but no change. There is also a blue dot about 1" in size in the very top right of the screen.

    i have the KF42we610 sony model. The unit looks great with the exception of a patch of blue dots in the middle of the screen. It covers an area the size of a dinner plate. Its not overpowering, but noticeable.

    My Sony KF42WE620 has a blue hue at the bottom left area that goes half way up the screen. I've had to replace the projector lamp just over 1 1/2 yrs. ago (not under warranty). The TV is just over 3yrs. old!

    I just noticed about 40 or 50 blue dots in the center of my $7000 KDF-70XBR950 TV. The killer is that the manufacture date is March 2005. It looks like the problem is getting progresivly worse with time. I'm just starting my communictions with Sony and I'm hoping for some recourse....if not I believe I will have a decent chance to recoupe my costs in small claims based on the well docmented history of the problem.

    I have the KF-50WE610 which is just about 5 years old. I just had to replace the Lamp 3 months ago (not under warranty) and I now have a football sized blue hue in the upper eft middle of my screen. Sony is claiming they will not cover it! Any suggestions?

    I have the Vega 50we610 and it started with blue dots in middle of screen and now covers the whole screen. There is also a blue hue from top to bottom on the right side of screen. This is also the second lamp replacement in less than 5 years. For this price of Tv and it being Sony Brand I am really disappointed.

    I have a sony TV 60" rear pro lcd model # KFWS60S1 with a blue streak at the bottom left corner and its getting bigger. it has a slight yellow haze in the middle of the screen and 4 blue dots. Its embarrassing to watch. I bought the product in AUG 2005. I realise its the optical block but I can't get any help from Sony as I have called them several times

Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )

You can try doing this, turn on the Tv and select the service menu, if that tint also shows on the menu, it's most probable to be your DMD board, but if it doesn't it might be the video board..

Blue section (corner) and blue dots

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.

My LCD TV Has 4 large round black spots (50mm diam) on the left side of the screen. I accidentally splashes a little water on the unit the day before, but in the bottom (right) corner only. It is a Teac...

The dots cannot be rectified, static dots of this kind on an LCD panel are dead pixels or liquid cristal leaks, depending on their hape and aspect.

The only fix is by replacing the LCD panel, that is an expensive part and must be ordered by phone, as it is not normally in stock.

You can inquire by phone here to find out part price.

Hey there Aleman500-

I had this exact same issue with mine. Started noticing the "blue cloud" on the bottom portion of the screen.

Please follow this link and the instructions listed. I opted for an "upgrade" that was offered (brand new 46" bravia lcd) but sony had also offered to fix my tv for free.

Happy New Year!
