Insignia Flat Screen TV - no cable signal

if it was a new tv you can ask the supplier for check up it was covered with warranty.

just upgrade, really not worth fixing. sounds like board is bad

If your trying to receive over the air make sure the TV is not set to a Cable mode, if your on Cable your new TV is most likely a ATSC tuner (digital) and the cable company can map channels any way they want. If your old TV had the older style cable tuner, the lineup will be different.
HDTV has level thresholds, if the signal is weak you wont see anything, but the old TV would.
Without knowing much about where or what sort of TV your using, these are my best ideas.

When I plug in all of the cables the tv says no signal. I have tried it on all different input settings and my cable provider tried sending me a stronger signal. Could I be doing something wrong and is there anything else I can try?On the back the tv has no receptor what else is there i can use?

i have a 26" insignia lcd tv that i use as a montor uou musr set the screen resolution on your computer to 1024x768. if you use a higher resolution it will say no signal.so use your montor to set the resolution to 1024x768 then hook it to the vga and it should work. bob griggs

Heres the dealyo.
Click start button
Click control panel
Click display
Click settings
adjust screen resolution (probably have to go down) until the tv displays your computer
if this did not work, you will have to adjust bit rate from 32 to 16. Fiddle with the settings until the magic happens.
You will not get any sound unless you use an audio jack plugged into t.v.

Im here all week

Did you check the cabling correctly
