Customer Question

I have an Igsignia(sp) TV and Comcast cable. Recently, when the tv is first turned on, the picture flashes between black screen and show and then this settles down after about 5 minutes. However, the tv occasionally chirps. I have had Comcast over and they don't have a clue but they did change my 740 tv to 1080 set up.

Hello and sorry you're having problems. I'm just getting online and seeing this question now.

Can you please get me the full model number off of the back of the TV?

Also how long have you owned it for?

As a test, when the screen goes black- please grab the original Insignia remote (not the Comcast remote) and press MENU- does the TV's native MENU also flicker?
