Depending which cables you are using, you should check your cables to see if you have them in the right order. The other issue with some ILO's they run really hot. Keep the TV away from the wall and allow air flow. If necessary, you may want to buy computer fans and mount them on top of the vents with air flowing outbound. (Using Coarse Thread Drywall Screws to mount-top two holes only) You will need to buy a universal adapter set to 12V. It will take some rigging with wires. (Red for positive and black for ground) Test the fans before mounting. The fans run independently. Also, you will need a switch to turn off the fans when TV is not in use. The problem with some models of ILO's , there are not enough vents for the heat build up. Where ever it's hottest on the back panel, place the exhaust fan there. On bigger screens you may want 2-3 exhaust fans. It is a $25-30.00 investment but your TV will last a lot longer...years

From some of the forum threads I've read about this, it seems like there were early issues due to bad firmware, but they have all be resolved with the recent updates. It also appears to be very easy to replace the hard drive. Just swap it out, format from the menu and you are done.
Hi, KP-51HW40 shuts off due to incorrect white balance and blue arch lines is an evidence of that incorrect white balance. I hope tv standby red light would flashing 5 times then 3 seconds pause and again 5 times when tv shuts down. This is rear projection tv that has three picture tubes (red-green-blue) inside to generate picture that projected at front screen. These three picture tubes must be drive with correct drive voltage to produce good picture of each color.
