    I have this same problem. I asked a saleman about this; he said to spray some canned air in and around the bulb and in and round where the bulb is mounted. I have removed the bulb and dusted off the bulb. I didn't use any canned air. This helped with some of the spots but not all of them. What else can I do?

    Same here! Purple spots everywhere and I thought maybe the screen needs cleaning. I'm interested in trying the "cleaning of the bulb method" if I can locate it. Any other tips?

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

My Sony Grand Wega LCD TV currently has a large blue spot on the left side of the screen when powered on. I have changed the lamp, but this did not solve the problem. Could this be caused by bad component...


Hi,
I'm afraid, it is problem of optics unit block (light engine), there are 3 LCDs red-green-blue for color picture formation and blue LCD sounds bad, please call local TV tech for fix.
Thanks.

Wega KDF-50WE655 has purple spots, support says wega engine bad


I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described sounds like one of the circuit boards that control the picture quality needs to be replaced. The cost of the board would likely be in excess of $200. There are usually several boards in a TV like that that control the picture and when one goes, you can get anything from lines in the picture to poor picture quality from blurriness. The main question is do you want to spend $1000 to fix a used TV?

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

Hi,
Green picture is caused by the light engine (the projection part of tv) failing and has to be replaced. Sony has extended the warranty on some models so you might be in lick. Contact them with model and serial number they can help setup repair if you qualify. If it is not covered it can cost between $1000-2000 to fix, which is way too much.
