SOURCE: Dark spots on LCD screen

I hate to say it but what this is is contamination under the actual LCD glass. This propblem starts during the manufacturing process and can rear its ugly head over time or after running at high temperatures for long periods of time. It can also appear as dark 'tiger' stripes. There is nothing that can be done to repair this. If you have an extended warranty, the mfg should exchange the panel for you. If your warranty is up, take photos and contact Toshiba online and try to get them to cover this regardless. This is a mfg defect.

Hello, I have a 40" Samsung LCD flatscreen. My television has a 2.5" diameter black spot on the far left side about 4" from the bottom of the screen, Also we have a dark transparent band across the bottom...


Sorry Sir but your LCD TV got wet... it can be splash with too much water, an animal urinate on the panel, etc....
this kind of black spot is caused when the LCD Panel Terminals got wet, this terminals are located at the lower side of the LCD Panel.

Dark spot on the right hand side of the screen


check make sure you didnt put your tv next to some thing that has a magnet in it such as speakers either from a radio or home surround sound system this will cause the problem and if its been sitting beside a magnet for awhile your probably not going to be able to fix it

Screen gets hot and turns black on the bottom right


There are many causes of this. On cause can be the Cold cathode fluorescent
tube itself. This is a grossly misnamed device as the cathodes get very hot
indeed. One of the tube failure modes as they wear out is that the cathodes
can get much hotter than normal, and this affects the screen near it.

DARK SPOTS!!!!!!!!!!!


Well depends on wether you what liquid you cleaned it with, because you are supposed to use the actual screen cleaner, if you use windex it takes off the finish on the TV and that may be what caused the dark spots. If not so I really do not recommed doing it yourself, it may just cause more problems, depending on when you bought the TV I recommed getting a TV repair man out there.

Dark Blotches


This is probably caused by dust, either on the mirror, lens, or possibly inside the light engine. There is a 5" dia hole on the side of the back of the tv where you can take out one screw and take the door off. this is just big enough for you to put your hand through to clean the mirror and lens. Hope this helps.

Mitsubishi WS-65511 Rear Projection Big Box TV resets with a green flashing light every 5 minutes, Then works fine for 5 more minutes (perfect picture). Acts up worse when cold. Warm it up Works hours It's NOT the DM board caps. I've already replaced the DM caps twice. Not the problem. No repairman will look at the set. Too Old. So am I. I could repair it with help. The power supply must have a safety circuit that will shut down & reset if too much draw. I DON'T have a diagram. I'm not sure how to trace it . Which board? If I unplug boards one at a time, Will it damage other boards ? I know it is NOT the 7 DM board caps everyone keeps telling me. I see no burn't parts, No bulging caps. Tapping on components doesn't reset. What kind of component would act up when cold , But not overdraw when warm? This set has the best beautiful picture when it runs. If you can get past the resetting every 5 minutes for the first hour, You can watch it sometimes for 20 hours. I've left it on at night & it is still on the next morning. Change the channel Or raise the volume, And off it goes. Once or 10 times, Keeps resetting. Then on for 4 or more hours, Maybe. I can't afford a new one. It works GREAT ! when it works. I've notice that even when the set is turned off, The green light starts flashing (resetting itself while it's off) , Then stops. Once in a hundred times it will kick off the breaker & you need to push reset with a pin on the front panel next to the green light. It's probably a 10 cent resistor OR a $ 1.00 cap. If I only had someone with more knowledge than me to help. I know how to use a meter & read a schematic. I built a Heathkit 25"TV in the 70's & all my novice ham gear. I'm 64 & not familiar with digital circuits. Can someone help PLEASE ?
