So I went out and got a 40'' insignia lcd 1080p tv from future shop tonight, so we get it home and unpack it and take out our old tv, which was an older RCA 27'' (not flat screen) as soon as we plug the new TV into the powerbar it blows the fuse in our apartment...I was thinking that the old tv would draw more power than the new one, is that the case that the new TV is using that much more power that its blowing the fuses or could it be something wrong internally?

You need to dertermine if the power board failing charred the connectors, or if a differeb=nt component failed which charred the connectors and took out the power board. This will require component level testing. i suggest taking it in to the repair shop.
However, i would price shop a comparable replacement TV before fixing a 4 year old Insignia. it may be more cost effective to just replace it.
I think your insignia is set for SHOP mode instead of HOME mode. I changed mine to HOME and it's working fine now. Press your menu button and then scroll down to setup. You're looking for Plug and PLay which should be the very first choice. If it's greyed out as mine was you'll have to change your imput from HDMI to TV in order to get to the P&P. Once you're in the Plug and Play your first choice is language. The second should be SHOP or HOME. Make sure to select HOME. You can skip scanning for channels. This fixed my problem with the blue light. The store uses SHOP so if someone plays around and changes something, all they have to do is shut off the TV and turn it back on. Please let me know if this works.
This tv is a lower end of the LCD tv.The problems u have is the major board of the tv,the tv Tuner signal board,this board is the board where the incomming broadcasting signal cable plug into it.Tries websites Like Shopjimmy.com,Ebay.com to buy a refurbish tv Tuner signal board for the replacement,if u have some machanical kills like taking things aparts and putting it back together again.The repairs shops prices,might cheap might not.Must take ur tv to like two or three shops getting diffrence estamates from those shops.Shop for a same tv model a new LCD tv compare it to the Shops estamates and u than decide,what action u want to take.
These things draw a huge surge current when turned on. What size fuse are you blowing? These things can surge 10-12 amps on turn-on. What about a fuse with a reset button. They will take alittle more surge before they go. Don't matter about the insignia working before because the cheaper sets tend to stay powered up more when off....thus not surging on from a dead start. Could you try a different plug on a different circuit/fuse? and see if that makes a difference. If you have a 15 amp fuse, then your pretty close with other stuff plugged in. What size is your service? Do you still have an original 60 amp box with screw in fuses? Is it an old house?
