    What do you mean by blurry exactly? a problem with the convergence correction circuitry will cause the set to shutdown but it will also appear that the colors on your screen do not 'line up' properly. Another common problem with these sets is for algae to grow in the coolant inside the blue gun and will cause the picture to look 'hazy.'

With the back off and if you can get a small mirror above the blue and the green tube, look at the picture coming out of the tube. If it looks like you're looking through fog then you probably have contaminated coolant. Compare them to the red tube for reference because the red one is very seldom affected.

If contaminated, the fluid will have to be changed and the chamber cleaned out by someone that knows what they are doing.

Be careful reaching in there. Wear gloves to help protect your hands.

you may have a dry joint on the screen controller board or a lose connection on to the screen. clean the board on the back of the screen. but take it out first and clean the copper parts on the screen cable.

Blurry picture


Just a shot in the dark but the first thing i do when i get a blurry rptv in my shop is clean the mirror. Dust can accumulate and create a blurred image. You must be careful however as some of the mirrors are Front Surface mirrors and require special cleaning solutions/techniques. If thats the case using a damp cloth could ruin the mirror. I hope this was helpful.

Can I clean the color bulbs on my 52'' RCA television?


To clean these lenses is easy with a clean soft cotton cloth in a kindly way. BUT wait a minute: To get access to those lenses is the really hard job. something as you want to see the core of an onion but tobe there you have to take a cover at the time. Trust me: Literally. Step by Step, at least 40 screws. the front screen is the last step, and then you can see those lenses. If the tv is working OK and is the only job needed, ask a technician for a regular cleanning and adjustment you can get surprised about the service cost (NOT REALLY HIGH i mean). make sure he cleans the back mirror also.

Sony rear projestion TV has blurry picture.


sounds as if your convergence needs to be set. either through the menu on the tv or remote you need to get to the convergence set screen and you need to line up the crosshairs. this usually happens when the tv is moved or bumped.

You need to clean the projector lens on the optical engine using a soft cotton or, better yet, a chamois cloth. Also clean the mirror mounted inside the rear cabinet and also the front and rear of the screen itself.
If picture is still blurred then your the optical engine is most probably defective.

Can I clean projection tubes myself?


First unplug set and remove back cover then you should see the three picture tubes . Using a soft cloth spray windex on the cloth then clean your lens and use the dry side to wipe away . Do not press hard as the lens are plastic . If you cannot see the tubes thru the back side you must enter thru the front . Would need to know make and model # of your set located on the if you need more assistance . If you are a smoker this could very well improve your picture . Good luck
