Yellow & dark spots on screen

I notice this when the screen displays lighter images such as sky blue images. I think I got a lemmon . T.V. is past warranty so I guess I am screwed ! I cleaned the screen and does not help . I am on disability which makes a expensive repair impossible . Won`t ever buy a sony T.V. again .

Re: yellow & dark spots on screen

Check with Sony because there are certain issues they will fix even if the warranty has expired. Our TV got blue spots on it and they are fixing it for free. It is two years old.

One yellow, one pink, and one blue spots appeared on my tv screen.

The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.

That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.

Not fixable.

Having a big yellow spot background in the middle of the picture.

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

We have a Hitachi 60V710 that is almost 5 years old. We have always noticed a bit of yellow haloing but recently our dog has jumped up onto the screen (unfortunately more than once) and now we have notice...

I do not think the Dog broke anything. I do think though the Optical Block assembly needs to be replaced to fix the problem. Do to the cost of repair, I would contact Hitachi to see if they could assist you in the cost and recommending a Service Facility near you to do the work.
I hope this helps,

I have a sony kf-42sx3oou, i have just had the lamp replaced, since replacing it a few blue spots appeared in the top right corner but today a yellow line has appeared on bottom left hand corner, could you...

This problem was probably there before, but you only noticed with the new "Brighter" bulb.

This TV will require replacement of the LCD Prism unit.

This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.

Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.

This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty. If out of warranty, I suggest living with it or selling it if out of warranty. Turn down the Brightness and it will not be as noticeable. I am sure you only see this with bright white backgrounds and such

Good luck.....

Blue blur on part of the ultra vision

Do you normally leave this set on a specific channel...such as CNBC or BLOOMBERG tv...etc that maintains a regular scrolling image???

If so...on sets that are a few/several years old...the projection tv screens can develop what's called a "burn" or "burned image" on the screen...similar to wearing a path in your carpet from heavy traffic areas. Newer models do not have this issues...but many older ones do.
