SOURCE: I GET WHITE SPOTS ON MY LCD SCREEN

this is a touchy subject for sony. basically sony has increased the brightness levels for the backlights to have better color tones in thier lcd's. well the downfall of this is the white spots you are experiencing. this is not a defect, you will never get them to go away, the only thing you can do is to turn the backlight and brightness down to reduce the white spots. if you contact sony, there is a software upgrade that will help reduce this issue...

SOURCE: Panasonic PT-52LCX15 green spot on screen

Easy fix. I had the same green dot problem and I removed the front panel (no screws). In the center is a panel that has two screws. Remove them and pull the cover off. There you will find the projection bulb. Do not clean the bulb but instead the base. Use a damp cloth to wipe the dust off the black disk (the base of the projection bulb housing). Apparently the dust through static electricity may cause enough magnetism to distort your picture. Hope this helps.

SOURCE: Vizio P4 Plasma green blotches

OK Service tech came out last night (7pm) and repalces the main board and updated firmware to the latest. he said the red/green snow is a fairly common problem with the early units (mine was a july 2006 build). Picture is fine now but we will see how long the fix lasts. Main board was definitely the issue, firmware upgrade was prob just because they could.
Keep in mind this unit was OUT of warranty. I find it refreshing that Vizio took responsibility and set up a service ticket for a 16 month old unit. Not that they shouldn't last a lot longer but they could have just said tough luck.

SOURCE: Sharp aquos has green and white vertical lines

You must contact a svc co. This is a upper or lower buffer board problem and possibly a control board. Nothing you have done wrong, it just happened.

Gray spots on screen on a JVC HDILA model HD 56G 787


The gray spots are caused by dust on your lens, very easy to clean.

Power down the TV.

If you open the right side access panel (right side as you are looking at the front of the TV) you can see it in the middle, it's not very big. Using a scratch/lint free cloth, gently wipe off the lens or use a vacuum to **** up the dust being careful not to actually touch the lens.

Replace the access panel and enjoy your spot free screen.

Split screen


It appears that it has something to do with Progressive Scan been turned on. Progressive Scan is a feature built in your dvd player, wich by using it, it would give you a better picture//resolution on your tv, you need to use Component or HDMI cables to hook up the dvd to your tv if you want this settings, but if you are using composite RCA cables (Red,White & Yellow) and the Progressive funtion is turned on by accident, it may give you a split screen, black & white, or no picture problems. Also if you are using Component (Blue, Green & Red) cables, if one of them is unplug, the picture can be out of colors, or no picture. Check this things, if not, write back with more details about your set up.

Try this procedure:

Adjust the green & blue CRT screens to match the red. Go into your picture menu adjust, turn color all the way down to a black & white picture. Now adjust each CRT screen so that you end up with a true black & white picture. Then adjust each focus control to get a sharp picture, and adjust each CRT focus one at a time for clarity by covering the other two up. Then go back into picture adjust and turn color half way up, you should see a better picture.


If you cannot get the blue & green to even out to a black & white screen you have other problems such as faulty CRT card on back of tube or it could even be that the video IC is faulty. If this is the case, then you may have to get a competent local technician to check the TV and get the necessary parts replaced.



Hope that helps...Should you have any further questions, please feel free to post them here.

3 green spots on the top center of my projection hd tv


I had a similar problem and brought it in to a technician for a quote of $860 to fix. The problem - speck of dust on the optics. If it weren't under warranty I would take it apart and blow off the dust myself.

Red spot in the middle of the screen


You most likely have a burn in on the surface of one of the picture tubes. What you need to do to confirm this, would be to take off the front screen, and with the set turned on, look directly into each one of the lenses, and see if you see a mark on the green or the blue tube. if this is the case, and I am pretty sure it is, the picture tube will need to be replaced, but this set is not a young thing, as the green faint lines is most likely a bad capacitor in the screen drive circuit. If the picture tube is indeed burned on the surface, most likely be better off buying a new TV set. Good Luck
