Long pause changing channels

you have to rescan for channels so it will recognize the channels

Same with our Insignia (19" LCD). Takes forever to change channels, and sluggish as heck in general. The viewing angle is poor, and the screen is not adjustable... We have a paperback book under the back part of it's flat base, so we can actually see the picture, without distortion and the shiny, aka "off the optimal viewing angle" silvery look. The picture (when watching it straight-on) and sound is fine, but the slow/sluggish performance, the tiny info and memo text, etc. makes it pain to use. Yes, It was "only" $100 + tax, but it should have a better, more acceptable performance and feature set.

on the off chance read the owner manual as the set may have a feature that locks the keyboard and the remote out

You may have a burnt out blacklight... You can fix it easy by having the tv on while it’s a bright picture than quickly unplugging it... or it would be best to get a new TV.

i hve the same tv and the same problem. heres the fix; you must take off the back cover so you have the back of the lcd exposed. its about 30 r so screws to get it all off. once you have the back panal off look at the side where the power button channel button and volume ect. button are. follow the wire thats connected to that, to the motherboard. simply unplug this wire from the mother board and use your remote control to change channels and power on off the unit from now on.

You can change this option by going to the "Channels" menu and selecting "Auto Channel Search." Additional details can be foundat InsigniaProducts.com, under the Support tab for your TV.

1. Cable company sending something through the line. Also th insigna has a different tuner. Also can the insignia find the digital channels using an antenna?

Insignia is Best Buy's store brand which is an LG tv. The power supply board needs to be tested to see if all the voltages it produces are present. If they are, then look at replacing the main board.

I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

I have one in my shop with the same problem. Power is the only function that works. I repaired the power supply six monts ago. Now it looks like a bad digital processor board which is non-repairable. I can't believe what's happened to the tv business. Absolutely disgusting!
