AFTER REPLACING THE LAMP, I HAD TO PUT THE COVER ON AND NOW THE SCREEN HAS TINY BLUE DOTS AND THE POWER LIGHT STAYS GREEN. THE LAMP LIGH IS NOW ON AND RED


The blue dots are due to a failing optic block. The lamp is only making them show up more obviously. The TV is probably failing as the blue dots will get larger and eventually take over the screen.

This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen.
Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube.
Local tv repair shop will help you for that.
Thanks

Blue dots on screen. what is it and can it be fixed? a new bulb was recently installed.


Yes,it is repairable.Blue dots on screen is sign of LCD failure at optical block assembly. There are three LCD on the optical assembly RED,GREEN and BLUE. Blue LCD failure causes blue dots on screen. Repair should be done by replacing blue LCD. Note! LCD replacement needs Extra care and precise tools such as oscilloscope and color pattern generator , for the color alignment after replacing LCD. But if you can afford, replacing the optical block is better,

3 round dots on screen yellow red blue


I have to be honest with you, I suspect the marks are burns on the three picture tubes and permanent.

A simple way to prove this that requires no technical knowledge:

Remove the back cover and locate the three large lens (red, green and blue tubes) and with the set on cover each lens one at a time; if a mark vanishes that tube is burnt in the middle.

If you have three dots or tear shaped marks the set arced and burnt a small area of each picture tube's screen.

These tubes are about 4x5 inches at the screen and are like a regular tv screen; there is a phospher coating and if the set arcs it will burn the coating away in the middle of the screen on each tube.

Confirm this and if true two things would have to happen: replace all three tubes (not worthwhile) and find what caused the arc.

I do not like to give people bad news but I am honest and if this input helped or informed you give this solution a "very helpful" rating as I do this here for free.


If you have ANY questions or need advice do not hesitate to post a comment here and I will respond.

Blue tints w/ tini blue dots


if you see blue pixel type groups of squares or dots you may have a burnt light engine and this is common in many LCD rear projection sets; a blue screen may mean the engine became burnt--LCD rear projection sets of this kind have an optical enginge--with red,green,blue prizims--sometimes they get burned by the lamp---a photo would tell me or most techs what the problem is---the cost of a replacement engine is very expensive--some models with this problem are covered by Sony even if the set is no longer in warrant

Converge off a little and screen has green tint


If you have the remote, go to the setup screen and move the picture. Converge has nothing to do with where the picture sits but, where the red, blue & green dots land. All you should see are pure white dots. There should be absolutely NO color ghost anywhere on the screen. If so, you need a bar / dot generator to set the convergence to center the dots.

Blue dots


You have a bad blue LCD in the light engine. Replacement of the light engine is the only fix and it usually will continue to get worse over time
