Toshiba 40" LCD TV 40RV525R Dog Dropped it :(

[itek]

Hi guys, sad day for a friend of mine- the dog somehow walked by and knocked over his 40" lcd.... he brought it over to me and fired it up;
The LCD is not cracked, but the screen shows a strange tan/whiteish panel that fades accross, then within minutes the entire panel starts fading tan/white.
Nothing is obviously broken or disconnected inside.. is this thing toast or might it be salvagable?
Thanks!

Strange looking failure for that type of scenerio. Since it was a drop, theres nothing I can think of besides a break in solder joint or those darn tab bonds. Keep with it, I think you'll find something.

im thinking check tcon, cables to and from tcon, boards on top of panel, ribbon cables from the boards top to the glass panel.

OK so I got down to the glass and found the top left corner is chipped, I'm guessing there is a trace that sends data along the edge of the glass there?
If I press around this left edge if affects the whiteness but it never goes away...

I'd sell it for parts. See what the boards are going for on Ebay and sell each one there. You might get $50 per board or more.

Hey y'all I don't know how to start a new question but I have a Toshiba 40RV525R that looks like it has experienced a de-lamination of the LCD screen.
Could someone confirm or tell me what to look for?
Thanks in advance !
I got this tv with a bad back light inverter & when I got it running this is what I found !
The mark does not go the entire width of the screen.

almost looks like it cracked, but I doubt it did. I'm thinking the zebra strip/ribbon cable coming out of the tcon. where it attaches to the glass some times becomes unsoldered.

I'd try going over it with a pencil eraser or something and push it gently into the glass to see if the solder broke. if you see a change in the picture then id push it down with silicon or something and apply heat from a soldering iron or something to solder that part on the ribbon cable back onto the glass.

If youre still around let me know how you fixed the inverter board, thats what I'm trying to fix.
