I just changed out the invertor boards and mine was fixed. I had the same problem. Im not a TV repair man but replace the board thats buzzing and it will work again.

Follow the following solutions, this should fix up your trouble
1. Turn yourmonitor on. It should be on for at least 20 minutes before you continue.
2.Press the"Auto/Select" button on the front of your computer's monitor. Thescreen will be wavy while the adjustment happens. When the screen stops beingwavy, the faded colors should no longer be visible.
Follow steps 1 and 2 if you do not have a disk for the monitor.

acoustic solutions lcd tv when i switch it on the screen flashes blue, green then red no picture??? it was working ok last night any ideas?

Here is what you need to do.

1.) You need to remove the entire plastic piece below the front of the screen. You most likely will find 3 screws on either side in back that you have to remove.

2.) The grill will not come out easy, pull from one side and then when it starts to come loose from the other side(there are several plastic pegs that hold it in.) Then from the bottom pull out( most of these sets have square plastic tabs at the top that tuck in.)

3.) With the grill removed locate the inspection plate behind it (it usually has 6 screws.) You will have to tilt the grill to the left and on its side as several cables are connected to it--they are held in place with trash bag like ties that you can release to get some room.

4.) With the inspection plate removed you will see a fairly small (about 3 inch square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with whiteout so someone can tell if they have been adjusted.

5.) You need to look very close at the block with a flashlight----usually the top three controls are FOCUS--don't touch those.
The lower three are usually marked Screen and if you look very close you will see b, g, r(blue green red)

6.)Usually the blue will be on the bottom left--it does vary

7.) Once you locate the BLUE screen control have the set on and turn it down--if the set is shutting down you may have only a few seconds to try to turn it down---usually to the left with the Blue Screen control.

8.) Best way to do this if the set is on is on a video input with nothing connected--you turn the blue down until the set stays on and then very slowly turn it up until you see a slightly blue screen with or without diagonal trace lines----if you get it to turn on this way turn the blue screen back down slowly until the blue screen and trace lines just disappear.

Let me know if you get it to work--Like I said if it is shutting down you may have to slowly turn the blue screen down a few times to get it to stay on.

I do this here for free and if this helps you at all give me a vote here--it costs you nothing.

blown cap in the power supply it will be domed on the top where it vented

this thing happened in my laptop also i got green screen fully
then when i hit it behind the screen it was gone but comes many times then again i would hit
later on the screen was completly lost then had to replace the screen
yous is a starting period so go to a nearby computer service and fix the screen

The Blue SCREEN setting is too high. These adjustments are located inside the TV behind the front panel. There are two screws behind covers and then a wooden panel to remove to access the adjustments. The leftmost set are for BLUE, the middle are GREEN, and the right are RED. The top row are FOCUS and the bottom are SCREEN. Focus will focus/unfocus the tube and Screen will adjust the power of that tube (there are 3 tubes, one for each color). If Screen is adjusted too high, horizontal lines will appear (my TV had red lines, but I played around with the knobs and saw that it could happen on any of the colors). Additionally, if SCREEN is set even higher than that, the tube could go so high that it turns the whole screen that color (in your case, blue). If this happens the TV will shut down, probably due to either overheating or overvolting. To fix this issue, turn the appropriate SCREEN dial down until the lines go away. In your case, you want to turn the lower left dial down. Don't turn it too far down, if you turn it more than necessary the TV can give you an AKB error (noted by the STANDBY light flashing a sequence of 5 blinks).

try adjusting your color tuners located inside tv behind speakers.
