42lv5400-ub no pic or sound help.

Hi all!!!

   Ok my 42lv5400-ub just decided that it doesn't show any picture and yes I have done the flashlight test and don't see any thing on screen as for sound I don't know. It was working just a few mins ago and now nothing. I did noticed that when I turn it on I get a   red led then I get 2 white flashing BUT the thing is that I found out that the TV is on because I can turn it off and I get the normal white led that turns on and off when the tv shuts down. So I didn't get the chance to test anything it happened late last night but I did took the time to take the back off for later today after work to check things out. I will try my T-CON power test thing to see if my lcd works with red, green, blue and white screen appearing. Still I'm asking anyone here for any advice so when I get back from work to test some of your suggestions and yes I do have the repair manual for it too. I do have a meter and a LED back light tester too. So thanks for any advice!!!!

THANKS in advance

Serge
