My sharp aquos has gone to a blue screen and message saying not supported, why has it done this?


Suddenly it is plugged into what? The TV only works when a signal is sent to it. The TV is probably fine, but of course it's the messenger. Must be where the problem is.

Cant watch tv through dvd play


Usually a blue screen means the external device isn't connected. Since it sometimes works, the first thing to try is a new connector lead, in case your old one is faulty

Blue line


good day.
The case you encounter with your unit is just a minor one. Most often caused by loose contacts particularly in the horizontal circuitry. Try to have the circuit be resoldered.

response is highly appreciated.

Olevia LT27HVX 27 just blue screen


I just had this same problem over the weekend. Is your TV hooked up via HDMI?? Mine was and i've been having problems with the tv image shrinking whenever i turn on the tv, so i would have to change the channel 1 or 2 times for the image to come up normally. On Saturday I went to change the channel and then all of a sudden I hearld this loud pop and when the image came on it was just a sky blue screen, I couldnt see anything, but I could hear the channel. So I disconnected the HDMI and hooked up the tv with component cables I had and now it works fine. I ordered a new HDMI cable just to see if it will work again. If not, i'm calling Olevia.

Sony KF50XBR800 Blue Shading


more than likely it is the optical assy. there are light filters inside and after using the tv for a period of time the glue on these filters fail causing the filter to fall. which is what you are seeing. sony has extnded the warranty on most of their optical assy to satisfy the consumers.
