My SAMSUNG PPM42M6H screen has horizontal grainy lines at the top of screen measuring about 7 inches and from right to left. Lower half seems OK. What should be done or replaced?


Check the ribbon cables in side the TV that connect to the panel. They are the left side looking at the back. Make sure they are all seated propporly. If that does not fix, then your Upper Y Buffer board needs to be replaced.

Z3 projector.3 years old. Blue tinge in one corner of projected picture. Grainy picture on dark scenes.


There may be some problem with your picture tube else try this that looks like retrace lines. Anyway, you should try to adjust screen pot not focus pot. Make sure you are turning blue screen pot (there are 3 focus pots and 3 screen pots) and do it slowly. If you turn it too much, it will affect your grayscale

My Canon SX210 IS is brand new. Just bought it on yesterday. The problem I'm having is that the LCD screen does not look sharp and clear when focusing on a subject. It looks grainy. Can you tell me if...


Some cameras display a grainy picture in low light. Do you have the camera set to the highest number of megapixels and fine image or do you have it set to a lower resolution to get more pictures on the card?

LCD screen with weird colors and out of focus


I dont have much info for you but I hope this helps, If your LCD screen has gons through an "accident" or if it is just in it's usual old age moment, It's time to replace the screen. You can do this yourself, or you can hire someone to do it, howeven it is not that hard, Go online to find some replacement LCD screens for that model Laptop and then the rest pretty much self explanatory

Fuzzy grainy screen on nikon coolpix camera


Did you see if it is in manual focus mode? Try to switch to auto in the menu, or do a complete reset in the menu. Who knows what the last person was doing when you last used it, hehe

LCD screen not sharp / focusing when taking pictures


This camera is ancient by today's standards, at least 8 years old.

Your focus problem is that the back display is very low resolution, so it will never show a sharp image. 9MP should give a decent image when you view it on a computer. If not, you probably need to part with the camera. it is not worth much these days anyway.
