Power on Blank Screen Can't Post

Insignia LCD TV:
When I turn on power, makes click, powers on, makes humming noise, green power light on, but screen is blank. No response to any commands such as menu, channel, volume, etc. Completely black/blank. Screen is on, is illuminated but black.

What could be the malfunction?

Any help is much appreciated. Thanks all! Smile

I'll presume No Audio, I'll presume backlight IS lit and I'll presume TV responds to POWER key ONLY, but I'm not going to presume which Insignia LCD TV it is. What about remote?

Thank you jts1957 for your quick response. Your presumptions are correct. TV only responds to power key only. I do not have a remote for device at this time.
Any suggestions??

Thank you! Smile

That's a shame. Wink

Model: NS-LCD32

Is this the lacking information you need?

Thank you again for your help. Smile

YOUR Best Buy TV?
FULL Model = NS-LCD32-09? US or CA?
Power LED action? Color?

Do you have DVM?

I do believe it's just "Model: NS-LCD32"

InsigniaŽ - 32" 720p Flat-Panel LCD HDTV

http://www.insigniaproducts.com/products/televisions/NS-LCD32.html

Above is a link to the exact TV with a list of all it's features and specifications.

No LED action/color or DVM to my knowledge and...
yes, "InsigniaŽ a Best Buy Exclusive brand offering affordable quality and innovative consumer electronics products designed with YOU in mind." Laugh

Green light during whole time set on?

Which (if either) is used in yours?
715T2830 MAIN BOARD?

OR

715T2968-D MAIN BOARD?

So much for Service literature ... I'd still hedge towards the Main board (Since you don't have a way to confirm that power board is putting out correct voltage(s)).
