Using a torch pointed at a 45 degree angle at the screen, see if you can see a partial picture. If so your inverter in the tv has gone, these can be replaced by a technician fairly easily. Or you can locate one on ebay and fit it yourself, just be careful with the backlight connectors. Gently wiggle them out side to side.

Power supply for dmtech wt20xt lcd tv


I have DMtech 20" with intergrated DVD and had the same problem- blue light lit on power switch but no response on power up.
I noticed that when the power cord was unplugged from the back of the TV the green LED on the power supply would brighten and consequently dim when plugged back in. Sometimes the blue light on the power switch would strobe very quickly but you had to look carfully for this.
I repeatedly unplugged the DIN type power plug from the back of the TV untill the green light on the power supply stayed a constant bright and there was no strobing on the blue light on the front of the TV, when I powered the TV on at this point the button worked again and the tv powered up with the silly tune then life in the screen. I did have to do this a good few times (I'm tenacious) but it did work!!!!!
Hope this helps someone else, cheers.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
