Hi, I have and LG 37" lcd about 2.5 yrs old. 4 Days ago it started flashing the connecting message ans then the whole screen started flashing from black to white and then it just went to a black screen, not off but black. During this time I have no sound, no menu, no response at all accept that the led flashes when a remote button is pushed and I am to shut it off with the remote. It stays this way for at least 30 minutes. When I turn it back the led flashes 14 times then comes on steady and sometimes the tv works for about 5 minutes or so. I have disconnected the verizon dvr and tested with just the dvd with the same results. Any help on this issue would be appreciated.
I was told that it was probably the main board. I feel comfortable replacing that but I don't know if the board would wavt to be flashed with firmware after install. Does anybody know?
Thanks for any help in advance !
