What is this on my screen>

If that's a rear-projection TV, you could indeed have something inside that's casting a fuzzy shadow on the screen. It happened to me. I had this visible fuzzy blob at the bottom of the image. Pulled the back of the set and found a spider web along with a dead spider. The spider was in the light path to the screen and casting a small shadow. Got rid of that, and cleaned a fairly heavy layer of dust off the 3 CRTs, and TV looked like new again.

Has it always been there? Could have been caused in manufacturing

Your issue is minor compared to the huge dust blob issues I had with my Mits WD 65733. But thanks to those dust blobs they replaced my TV with a WD 73835 at no charge.

Depends what sort of clouding/flashlight issues your panel has,if any?

If you cant notice it from where you are watching from,and your panel has no noticable clouds etc,then I would personally stick with what you have now.
You could end up with a panel that has very bad clouding .

if you can at no charge to you ,i would do it now .

You paid for a perfect tv and you should get one

hey guys I have a very similar problem to what test is showing on his 650.

Any ideas what I can do to fix this or what the problem is?

Im thinking of getting the LCD panel replaced.

Hi Viper & Test,

Its such a tough call as to whether to swap ,as the risk of getting something worse is there.I'm not sure what the cause of your problem is,but its down to what you notice when watching films/tv etc.

I had really bad clouding and flashlighting on my first 650 panel,and it was noticable in normal viewing (dark films like Blade Runner,The Crow etc ),so it was a fairly easy decision to have a replacement panel fitted under warranty.
I thought about living with it,but I just couldn't,my eyes were drawn to the clouds every time a dark scene came on.
I had some luck in getting an "almost" problem free panel,no clouds visible at anything but high backlights,and very minor flashlighting from one corner.

I dont think theres many "perfect" larger size LCD screens about,almost all exibit some form of problem that people like us notice ,and get annoyed by.
Basically,if it was me,and I kept seeing the imperfection,I would have it replaced.
It's a horrible position to be in though,very frustrating to have these sort of issues when you have laid out this much cash.

I forgot to mention ,it makes me wonder whether a lot of the problems like flashlighting are caused by the amount of torque applied to the set's case screws.The techs that replaced my panel were muttering to each other about the tightness when they came to undo the screws to remove my existing panel.

The panel they fitted had never been fixed to anything before,and was almost perfect.Maybe its just a coincidence,I'm not sure.

yeah...well I think this is a piece of dirt on the top left part of the screen,or maybe a small crack. Whatever it is its annoying me so i called today and will be getting the LCD panel replaced hopefully sometime next week.

I only have one flashlight and some minor clouding on the top left part of the screen. I really hope my next panel wont be any worse...

no they are changing the LCD panel inside the TV. Its a PART

The dark spots are crap in the light guide in the backlight. It also appears to have some non-uniformities and they are "clouds" (what a dumb term) caused by, as mentioned above, by uneven pressure of the plastic housing.

There is no cracks. Cracks are fatal, immediately (and they don't look like this).

These problems are inside the LCD cell inside the set. The cell needs to be cleaned but they will probably throw it away after they unsucessfully convince you that its in your head.

So will changing the LCD panel (which im doing) fix my problem?

Sadly, only an airgun is really required to clean out the crap. But it is inside the LCD inside the set, so yes. The LCD manufactures have specs on "black spot" and 'white spot" contamination (size and density).

I don't know the brand by reading your part number, but this level of contamination speaks to second tier manufacturers who buy second grade displays. Sometimes quality has a price.

uhh mines a sony. I dont think they get much more expensive than that.

Bummer.

im just hoping the new panel im getting soon will fix this issue without creating anymore...

get them to replace the panel
