Blue blothes on LCD screen

I have the exact think happening on my Samsung LN46A530 and it has just been 2 years since I bought it. There better be a cheap fix for this because a $2,000 product has to last a lot longer than 2 years.

This is not a cheap fix, but call sony they know about this problem and have sent out new TVs to people who have had the issue, I have had about 7 out of ten people who call into sony get brand new sets FREE, so tell them that your optical engine need to be replaced at around $900-1300 and how old it is and the S#, they may not do anything for you but I would try, good luck

If you are sure its not a stain. then its a dead pixel on your monitor.. sooner or later it will spread out. To be sure if its a dead pixel, run your monitor in different colors, black screen, green, red and blue.. If the spots stays then its dead pixel.. You will be replacing the lcd when time comes that it spreads out.

No,ur Main Tuner signal board is the problems.Because when the LCD inverter board problems,u get no video or any backlight to the LCD screen at all,only sound.

maybe or maybe not. It is a pixel that is stuck 'on' all the time. Not a warranty claim item as a few bad pixels are allowed.....

It does not spread, but that is not to say that another pixel somewhere else on the screen will not go bad.

Replace the video board, if you can find one. Letting it cool down will not help any.

Me too! Is this a related light engine problem that people are experiencing with the "red cloud" in the middle of the screen? I just replaced the lamp, which I thought was the problem, but nope, the blue is still there. So definitely not the lamp. I don't know what to do?

I am guessing that this is an LCD projection set, Please post the make and model so I can confirm. In the mean time, if it is an LCD, there are 2 possiblities.

1) The lamp may require changing. Sometimes the inner surface deteriorates because of the heat.
2) The "light engine" requires replacement as the heat and light have started to burn the LCD surface. This burning starts to show up as a yellowing usually onm one side first and spreading to the other side.

This sounds classic to a thermo problem where a part(s) are becoming thermo sensitive with aga and use. When the set is cold and then warmed up, the defective part(s) is changing characteristics.

Some components became thermo sensitive that are driving the display. Or an embeded component in the display itself became thermo sensitive. It is very possible that the fault is on the board that does the X - Y addressing or on the backplane electronics of the display screen itself.

Using the set with defective components is a bad idea. If the part(s) fail completely and go shorted or opened, other more costly damage can be done.

The service rep for the manufacture of your set is equiped and trained to be able to troubleshoot and service your set.

You will have to take the set in to have it serviced.

I have never heard or seen this problem, i would change the lamp and if it's not it at least you have a backup lamp.
