Question about Toshiba 27A30 27" TV
Why can't I get a picture or sound? picture froze in the middle of watching. after turning off I turned back on, and there is no picture or sound, colorstream is showing 3 plugs down, how do I get the picture and sound to come back. No one has touched the back, so nothing should have come out?

1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.

I would try a power drain: Unplug the TV's power cable so the TV is not grounded to the house. Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens. If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.

ur AC fuse might be burn out or SMPS (power supply unit) might be damage. to check the first case, open the cabinet and locate for the fuse following the AC cable. if it burns out change it else take it to a authorized service man.
