White sparkly spots on screen

Spot remover. Black marker? Maybe not. (;^D).
Really, if it's just a little white dot on the screen, it may just be a bad pixel. Those things happen. The manufacturers warranty against more than 'so many' bad pixels, but if there's just one, I doubt they would replace it. If it's a big block of white, you might be able to get it replaced.

Sounds like you are describing stuck/dead pixel.

There is no fix, it is a Pixel gone out in display panel, good chance it is just stuck and will right itself but sadly sometimes they dont and the only fix is to replace the entire display panel
Manufactures warrant such defects different depending on amount of dead pixels on screen is considered faulty, ie 3 pixels grouped or 5 separate ones .

You may have bad pixels. What type of TV is it?

Do you mean dead pixels or a dirt spot ??

A dirt spot, use hot water on a soft cloth to clean it.

Dead pixels, you can try this, keep moving between screen and sometimes this will unstick bad pixels.


Go here, then click F11, now RT click mouse button as fast as your finger can. do it like 20 times.

Now click F11 on the page that shows the words dead pixel test.
If they are still there you will need to check your warranty and see how many the company allows before they will fix.

HI,
Are you sure that there is balck dot on the sreen. Check one more time is it any dust on the screen.
Black spot Means pixel of the Lcd sreen is fault. There are thousands of pixels in an lcd screen. when any of the pixel or a group of pixels become faulty the black spot will appear. Its not possile to rectify the problem other than replacing the LCD panle if its avilable. The avilability of lcd screen is very rare.

On a WS-73735 the white spots usually mean a failing or damaged optical light engine.

It is a major part----Google the model number with "problems" or "light engine" etc.

LG TV'S ARE SOFTWARE UPDATEABLE. UNFORTUNATELY, THIS MEANS A TRIP TO AN LG SERVICE CENTRE.

It's a bad pixel spot. I have a TV that has a dark spot.
Nothing you can do about it.

dark spot could be a faulty led. if you put a program on that is in white screen you should see all the leds light up the screen. dark spot will be were the led is not working. if on white screen and they all lite up but still dark around the area, it could be the lcd screen. and could be dying pixels. and try this video https://youtu.be/wlA2rcrAOCs
