This is going to be either a voltage adjustment or a faulty control board and/or Y sustain board.

You need to have a qualified technician check the voltages on these boards to determine if they need to be adjusted or else (if the voltages are fine) these boards will need to be replaced.

TV will shut off after 2-5 minutes


It is probable that there is power supply trouble. Visual examination of capacitors does not reveal internal electrical failure.

My Toshiba LCD suddenly started showing green pixels throughout the picture. It can really be seen in the darker areas. It will also outline dark areas with green pixels.


Does this only happen when watching TV? Or on every input on the TV?

Ensure the connections between your cable source and the TV are solid and in place. Let me know if this fixes it, if not we'll move onto other solutions.

My brand new LG 37' Led/Lcd t.v. had four very light white spots that you can see in the background what causes this?


Hello
Dead and Stuck Pixels
Pixel defects for an LCD monitor are defined as one of two types: dead or stuck. Technically, both types of pixel defects are stuck pixels but it really deals with the electrical currents and the state of each pixel or sub-pixel.
A dead pixel is defined as a pixel or set of sub-pixels that has failed and is permanently in the off position. This condition means that the pixel will not let any light through. This can be observed as a dark or black spot on a brightly colored or white background.
A stuck pixel is defined as a pixel or sub-pixel that has failed and is permanently in the on position. This can be either with a single or multiple sub-pixels for a given pixel and is best observed on a dark or black background. A white pixel means all three sub-pixels have failed while a green, red or blue pixel means one of the sub-pixels has failed.
Hope this helps, if so do rate the solution

My 20 lg powers up, red light turns green, but no picture comes up, the channel id shows then it goes dark. I can wait up to ten minutes still no picture unless I change the channel a few times then it...


You wont want to hear this.....

Green dots on a LCD screen are burnt out pixels and unfortunately are incurable other than having the TV serviced at a high price. One of the reasons it is a good idea to get a warranty on these types of TVs is primarily due to this very problem....burnt out pixels.

Please rate my help++++Thanks for using FIXYA
