Mono chrome didn't do much but remove the color.
There's a TV that I was messing with(an older Sony Bravia LCD) and it actually has a setting where it would change the picture to a "negative" looking image which looks like what my TV is stuck with. It's a setting that says something like "Invert"...

What do you mean by "legend"? I'm no "Tech" I generally work on cars and stuff. Here's the pic of the T-Con and the connector I tested....Leave a comment:

Re: Sharp LC-52D64U-Negative picture
T-Con #3(2nd one from ShopJimmy)is in there LOL. Monochrome doesn't do much but remove whatever color is left in the negative imageLeave a comment:

Re: Sharp LC-52D64U-Negative picture
New board is an exact match with the old one(only 2 types for this model). I put the old board back in and the TV fired up normally(with negetive image) Put the new board in again same clicking no power, did the force power on and the TV fired up with the negative images. Probably could get the TV to fire up with the new board if I clear the error codes in the diagnostic mode. But got the kids running around right now so it'll need to wait. Any Ideas?Last edited by buuhaahaa; 09-13-2012, 09:32 PM.Leave a comment:

Re: Sharp LC-52D64U-Negative picture
OK, I did a "force power on" Hold channel down+Hold volume up and then connect the power cord. TV fired up but negative image issue resumes. Any ideas?Leave a comment:

@tom66 or anyone who can help......
Replaced main board and symptoms changed. Connected the power and I get 2 clicks. TV doesn't fire up. Green OPC and Power lights flash together once then the green Power light flashes once by itself then repeats. Thanks.Leave a comment:

Re: Sharp LC-52D64U-Negative picture
Contacted ShopJimmy about their T-Con board(discoloration and cracks can be seen in their advertised pics, if you zoom in) and they gladly exchanged it for another. Hmmmmmmmmmmmm, same discolration on the new board but not as bad no cracks. Same negative image result. My guess that the T-Con board is not the issue. Has anyone seen or heard about the symptoms that my TV is having??? Suggestions on any test to try???Leave a comment:

Re: Sharp LC-52D64U-Negative picture
sent them a message about an exchange, so I'll need to wait and see what their response is. But I hope someone can recall anyone else having the same type of picture problem I have and what the remedy was......hopefully not a bad panel.Leave a comment:

Re: Sharp LC-52D64U-Negative picture
Any other vendor worth trusting for a T-Con? "New other (see details)" runs around $50 US....USED $20-$30. Which route would you take for another T-ConLeave a comment:

Re: Sharp LC-52D64U-Negative picture
Just popped in a T-Con fresh from Shop Jimmy and no change in problem. The odds on it being bad too and producing the same issue is.........I'm no tech, so not sure.Leave a comment:

Sharp LC-52D64U-Negative picture
Had this tv for about 3 years and it developed this "Negative Picture" like a photo negative. Sound on this set works fine, negative picture is on all inputs. Did a reset from diagnostic screen(Volume down+Input>Connect power etc.....) same result. Found a video on Youtube(2 years old, fix in comments- [url]http://www.youtube.com/watch?v=UEfa-vjTeTI&feature=related[/url] ) featuring a Samsung LCD with the similar issue and took the tv apart found the said board to be insulated from touching any metal so the problem wasn't there. Found this thread( [url]http://www.avsforum.com/t/1170984/sony-bravia-xbr4-negative-picture-problemhttp://www.avsforum.com/forums/threads/add/forumId/166#[/url]...
