Blue spots like stars on sony wega


Sorry to be the bearer of bad news but this is a very common problem on the older sony wega tv's that were rear projection LCD sets. You will see dark bluish corners of the screen. It will get worse and there is no cheap way to fix it. All of these sets have this disease. In some rare cases Sony will repair out of warranty. You probably noticed this soon after you replaced the lamp on your TV. Some of the replacement lamps burn hotter than intended and start melting the glue that holds the light tunnel and LCD panels together to the light engine. In order to fix, you would have to replace the entire light engine assembly.

I have blue hazy streaks and tiny blue dots on my lcd tv


You need a light engine. I do not remember if your model is still under Sony's recall. You might want to call them.

Hello, I have an LG lcd rear projection tv and parts of the screen are turning blue, do you think it's just the bulb or the light engine?


Hey there first of all your tv is a lcd rear projection set, this tv's don't have a light engine system, they use a optical block

whats happpening is that one of your lcd chips is burning out and this problem will start to get worst, to be honest with you it's very hard to purchase just the LCD chips, you need to buy the optical block to fix your set, also the bulb has nothing to do with the color the bulb just shoots out light.

please rate this solution!!!!!

Jvc 70' lcd tv. power indicator light flashes fast upon power up. no picture


The lamp is burned out, this is an easy fix. Contrary to what the "repairmen" on this site say, you can do it at home with ease. Just type your model into a search engine and order your lamp, they come with great instuctions on how to install.

55 inch hitachi lcd projection tv has yellow and purple blur near the center of the screen


This, sadly is getting to be a very common problem with all Projection LCD TV's
Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses on one of the LCD panels themselves which are all located in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and visually inspecting the lamp itself and the lens that it shines onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly. Have a tech confirm-Get an estimate -Be sure to vote/rate me if this helped Thanks!

My hitachi 50VS69A tv shows the picture green.


A green image is usually due to a lack of red or especially blue. the problem is becoming all too common with hitachi lcd projection sets. what happens is that one of the lenses in the optical block (or light engine) starts to burn or discolor due to overheating because of a blocked air filter causing poor air (cooling) circulation. Nothing can be done when the damage is too far gone except to replace the light engine-at acost that makes it not worth repair. if the damage is minimal than to reduce further damage the air filter should be replaced. Light engine needsto be removed in order to replace the air filter.
