Half the screen is black


The white dots are most likely to be failed pixels in the LCD screen. When the picture elements fail, they switch to clear and what you see as white is the backlighting.

The overheating issue in laptops is generally caused by dust and fluff blocking the cooling fins and ducts or a failed cooling fan, but it could also be caused by a hung process which runs the CPU at a high processing speed. Press control (CTRL) ALT and DEL and look at the task manager and see if you can see any processes that are running constantly near or at 100% to eliminate this being the problem.

The failing display is unlikely to be related to the overheating issue.

My samsung tv overheated and half if it went black


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Black screen


It may be repairable, but you will spend less money to replace it.
You did not mention if this is a CRT or a LCD monitor.
If it is a CRT the Rasters and flyback are faulty causing dead areas on the screen.
If it is a LCD then you are having pixels dying, and it will not last too much longer.
You may want to try it on another computer just to verify that it is not your video card.

Black out screen


I had the same problem once with my RCA television. It only happened on certain channels and didn't happen during commercial breaks. If I adjusted the volume on the tv the box went away, but came back shortly after. The problem ended up being some malfunction in the closed captioning. I turned it all off and changed the CC settings and never had the problem again.

Half screen activated only


When only a half screen is produced, it is usually a upper or lower buffer board, if the top half is blank then it is the upper buffer, and of course if it's the bottom half then it's the bottom buffer board
