Invalid format error with P1600 blu-ray and LG LCD TV 42"
It may be a firmware issue if hdmi works with other items such as playstation.
If no hdmi the main Pcb hdmi ports are bad and the main Pcb would have to be replaced.

Consumers cannot upgrade the firmware so a shop would be the only option.

Invalid format
Try rechecking all wire connections for proper placement and fit too and from the tv.
Try adjusting the video format on the DVD, flip through 480p and 1080i. See which format works best with your tv. Do the same with Wii.

See if this helps.

Cant connect to pc
It high definition digital signal. You will need a HD cable not a vga (that is analog).
Check in you tv manual. It should give you options of what cable to use. May need the HDMI cable.

RGBPC input showing invalid format after move
There is nothing wrong with the connection, your TV or computer. Just changw the resolution settings under the display properties. Start with the lowest setting 800X600 and move your way up. It will eventually appear.

Zenith Z42P3 "Invalid Format" message from upconverter DVD
Ran into the same problem with this DVD player and my LG tv. Try this:
Open the DVD tray, with the DVD tray open press the HDMI select button until the proper resolution for your tv is illuminated, put the DVD back in, close the tray and try again. Simple fix -- worked beautifully for me.

Good luck
