SOURCE: Red Spots on 42" LG plasma t.v.

The dancing spots can be sorted by you taking the back panel off and adjusting the va and vs adjusting nobs , you will need a multimeter so you you can adjust the voltage to the right settings that are on a sticker on the back of the panel. You must remember to connect the black pointer to the earthed wire to get and the red to the live wire that has va or vs at the end of it. The right voltage measurements will be be found on a sticker at the back of the panel.
I advise you not to touch the setup and setdn nobs as these are factory settings and should not be touched.
If the va and vs do not sought the problem then try the vy and vsc adjusting nobs but only touch those if the va and vs does not fix your problem first.
Once you have done everything right your tv should be better then before with clearer pictures.
I hope this helps and be careful not to get zapped.

SOURCE: Picture dims dramatically

I have the same problem so far the best I could do was to put the user setting to sports and brighten up the tv as much possible without making the picture look too bad. Good Luck

LG W2261 VP HDMI problem, 1920:1080 doesnt fit right, there is 2cm dark screen at the edge of the display Got drivers installed for analog -vga and digital -hdmi Tried the buttons on monitor...doesnt...


This problem seem to be the LCD screen have dead pixels or a bruise spots on the LCD screen itself that why you have dark spot or spots on the LCD Screen.This problems can't be repair because this problems doesn't causes by the electronic circuit boards.Tried move the monitor as an angles to the right or to the left might help some lessen the dark spot on the LCD screen that all you could do.If this problems is a very dard bruised spot will not help all or if it is dead pixels on the LCD screen itself.

Tv has died


When the TV is on, if you look at the screen and can see dark images, then you will need to replace both the inverters. The inverters drive/power the back light inside the LCD to show the images. You may have to try and different channels and or inputs to truly see if you can see dark images while the TV is on. If you are hearing audio from a channel or an input then you should be able to see the dark images if just the inverters are bad.
If the screen is dead black without any dark images, then typically your LCD screen/module is bad.
If the TV powers up (power supply is good), you have audio and the remote will work with the TV (the main board is good), the only parts left is the inverters or the LCD screen/module.
I can get you LG part numbers if you need them.

Canon power shot sd1000 black dot on lens


If by saying the upper right corner of the lens you really mean that there is a dark spot on each image AND the rear display, there may be dirt or dust on the lens itself. Clean the lens with an optical quality cleaner. Do not use paper towels and Windex or the like - as paper towels can scratch the lens.

It is also possible that the dark spot is a "stuck pixel" on the image sensor inside the camera. There is no way to repair a stuck pixel outside of replacing the sensor. Any dark spot (regardless of source) can be edited out by using image editing software. This will allow you to to make the dark spot less noticeable - or practically invisible.

If the dark spot is on the rear display only, it can also be a result of a "stuck pixel" on the display itself. This should not show up an images, but only on the display. There is little that can be done outside of replacing the entire rear screen.

There are other things that can cause these problems, but those listed above are the most common.

I hope this was Very Helpful and good luck!

Acer Travelmate LCD screen went dark


The same thing happened on my HP. I ended up buying a LCD screen off ebay. That corrected the problem. New screens cost $150+. You can get one off ebay for half the price.
