Question about Sony KDF-E55A20 55 in. LCD Television

1 Answer

Spots on screen

I have circular dark spots on my screen in various places that can only be seen when it's a bright scene. They are about the size of a quarter and are more like a shadow than a dark spot. I've cleaned the screen, but to no avail. Any ideas? Thanks so much!

Youlikely have dust inside the optical block on the LCD panels. Cleaning the panels is a tricky job and just shooting compressed air into the block will only redistribute the dust. A qualified tech can disassemle the block and clean the panels

Why do i have dark smudges on my tv


Usually that is actually dust that has gotten in behind the lcd screen.The dust congregates on top of the tv and eventually falls in through the air grids. Im not to sure how to rectify this without opening the tv up not something I would recommend and can break your warranty.

White spots tv screen


Bright and dark spots on screen might be due to the fault of the screen itself. In some cases, it will be reparable. Contact any service technician, because, if it is a repairable fault, the panel might need to disassemble.

White fog "ring" around outer third of screen. Dark spots and a single white pinhole in picture as well.


If the model above is correct you are describing a bad optical light engine, about the most expensive part inside that set.

Dell w4201c no picture just bright colored spots


Was this set moved or transported? Is it possible someone struck the screen even if mildly?

If you can take a few good pictures and post them somewhere on the internet and provide the location--seeing what it looks like might tell what is wrong.

A classic description: set comes on but is a black swirling cloud where images can be dimly seen but are not clear--gets a little better after a few minutes but never gets normal.

Flat panel TV shows a bright pinpoint of light in dark scenes


maybe or maybe not. It is a pixel that is stuck 'on' all the time. Not a warranty claim item as a few bad pixels are allowed.....

It does not spread, but that is not to say that another pixel somewhere else on the screen will not go bad.

Dark spots on LCD screen


I hate to say it but what this is is contamination under the actual LCD glass. This propblem starts during the manufacturing process and can rear its ugly head over time or after running at high temperatures for long periods of time. It can also appear as dark 'tiger' stripes. There is nothing that can be done to repair this. If you have an extended warranty, the mfg should exchange the panel for you. If your warranty is up, take photos and contact Toshiba online and try to get them to cover this regardless. This is a mfg defect.

A dark but transparent horizontal line has appeared about 20% down from the top. Any suggestions? Originally there was a dark horizontal line almost in the center of the screen. I would go away after of...


Mine had the horizontal lines you are talking about. 1st check a test picture. Click on Menu, then Settings, then go to Product Support. From there click System Diagnosis and go to bottom and click on sample picture. If you see the same problem there, then you may want to research the possibility of installing a t-con board. You may want to try calling Sony 1st and have them walk you through the basic service repair items. I was very lucky and installed a new t-con board I purchased with all the other boards on Ebay. Good luck with solving your problem! Ron
