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.

I have numerous blue dots and blue streak at the bottom of the screen on my Sony KDF-50WE655. I replaced the lamp with a brand new one and the blue dots and streak are still present. any suggestions?

The problem it's not on the Lamp, the problem is the color wheel, you need replace it and the TV will work like new again. I hope this help you :D

My screen has little dots appearing sometimes red sometimes blues behind the picture i just replaced the lamp bulb as i thought it would cure the problem

the projection tube needs to be adjust for color alignment, each tube (red, green, blue) must be aligned so you there would be no color smear appear on screen. if it is aligned try to set up the color balance, hue etc.

Little white and gray dots started appearing on the screen it looks like star constellations??

If the dots are twinkling then you have bad pixels, if they don't twinkle I'd say there is dust built up in the optics and needs to be cleaned, which to do properly the top needs to be removed to allow access to the optical engine to do this. I recommend keeping the unit in a plastic bag when not in use to prevent dust build up.

Little blue dots on screen and large blue haze in upper left corn

Sounds like the light engine is going bad...that's why they stopped making these rear projection sets using LCD's. Costs almost as much as a new set! But get a second opinion before trashing it.

Howdy,

It sounds like the Lite Engine/Optical Block is bad. Sony has recall on most Models and will replace this part at little or no cost to you. So, call Sony at 1-239-768-7547. Hours: Mon-Fri 9:00AM-10:00PM / Sat-Sun 10:30AM-7:15PM EST.

Good Luck, Big Irish.

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

Sony grand wega kdf 50we655 blue dots everywhere

thats a common symptom for that model which is usually related to the optical block. Very exspensive repair. Check with a sony authorized repair center as Sony has recognized the problem and offer assistance with certain models yours may be one of the ones affected.

I haven’t actually worked on this model, but I can tell you that the problem is NOT the lamp. You asked how you can tell when the lamp needs replacement, on the front there is a indictor labeled “lamp.” It will be flashing when the lamp does need replacement.

Being a LCD (quite like the LCD on your computer) over time you can develop bad Pixels. I am sorry I don’t have a fix for you, but I do hope you invested in the extended service plan on this one.
Best of luck to you!

Testimonial: "Thank you. I guess i'll get rid of it because i got it second-hand."

Hahaha, Yes get what you can at the yard sale. Maybe the third hand owner will not mind the
little dots J
Every hour it’s on the lamp is getting closer to burning out.

Your problem is with the Optical Block. I had the same issue several years ago and Sony covered it. If they do not cover you'll need a new TV - it's over $1k.

Testimonial: "That sounds bleak so i bet it's true. Oh well, i only bought it for $700."
