Just in the last couple of days, I noticed a tiny white spot on the screen of my 40L3400 LED Toshiba television in the lower right hand corner. It is not visible unless the background (picture) is very dark. The size of the spot is pinhead size or even smaller. If it gets no worse, it shouldn't be much of an issue. But I am afraid of more of these spots, or that this one may grow.

Does anyone know what causes this? It is like that spot is always lit up, even when the rest of the screen is black.

Is it repairable, or would that require an entire new screen?

I think it's just a pixel that stuck in the on mode. That type of thing is not that infrequent, and wouldn't probably be covered by the warranty. You're probably stuck with it.

You have a bad pixel, fairly common when flat screens first came on the market. You can try and massage it out, gently rub it....No I'm not joking. Might want to use microfiber cloth to make sure you do not damage the surface of the screen. You may have to repeat this process a few times.

Havent used it but you can try this:

You'll need to use computer to as source.

I'm out of warranty anyway. The TV is almost a year old. However, I wondered if it could be corrected.

By the way, you said it is not uncommon. Do screens tend to get a lot of these? By the way, please note....it is an LED TV, not an LCD.

I haven't seen many issues with modern screens, when they first came out it was acceptable for it to ship with X amount of bad ones.

They are both LCD, the LED-LCD is how it's backlit.

With a little research, I've found that a white dot like this is considered a "hot" pixel.

I've tried the programs on YouTube that quickly cycle through red/blue/green, but as yet, no luck.

I have actually never heard of this, let alone tried this. I always assumed once you got the stuck pixels, there was nothing you could do about it. I actually have several "white" pixels" on my 70" Vizio. We have only had the TV for less than two years, so if there is a way to fix these white pixels, I'm all for that!
