Tip & How-To about Televison & Video

Sony projector has yellow or blue dots.

You turn on your big Sony projector one day and see yellow or blue dots on the screen. No amount of adjusting will get rid of them. What can you do?

You could replace the optical engine because that is the problem. The crystal panels are defective and starting to go bad. Alot of these units were made and they are failing on a regular basis now. If you want to tackle replacing the optical engine I have a tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine which will help with the removal and replacement as well as where to get the parts at the best price. That will be the sticking point. The cost of an optical engine can be $350.00 USD or more (think Sony).

Another option would be to go to this site by Steve Linke at http://sites.google.com/site/sonylcdrptvproblems/ which is well written and describes the problem in detail as well as options which you may have with Sony.

In the end you will have to decide if you want to spend more than $350.00 USD on an optical block which may go bad in several years.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

I have small blue dots and a yellow shadow in the middle of my screen


The model indicated uses what is called a Optical Light Engine, it is a very expensive part and likely is your problem---not much else will cause this trouble.

Let me know if you have questions.

blue dots center and yellow stain right hand corner on 60'' sonytv


Yes, I do. It needs a new light engine. Very costly repair. However, Sony has extended the warranty on many of these LED projector sets. You need to call a local Sony authorized service center and see if your model is covered. Otherwise this repair could run over a thousand bucks.

Large dot in the middle of the projected display


there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

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 : )
