LG 32LX1D half screen bad picture

[mcross]

Ok guys what its doing is the right half of screen is green lines, also last time powered on was not showing the video , but had sound, then it would flicker the video, warmed the main board with heat gun on caps (the 4 470 16v smts at the top left on the main board) flicking stoped video stayed but still half video all washed out?

power lines all look good.
Thanks
Mike

I have seen this problem before, the one I fixed was due to loose/dirty connection on the LVDS cable, this cable is attached to the T-CON board on the LCD panel assembly.
I see the end of this cable attached to the main board top center, but to get to the other end will require a lot of disassembly! You may as well reseat the cable between the t-con and the LCD panel at the same time.

From what you have tried it would suggest cap replacement would help. However the
picture of the board is too blurred when enlarged. Can you do a picture of each board
clear enough for us to see the component descriptions.
In heating the caps you may have also heated other components which have affected the output voltages. What make /series are the caps.
Please can you update your profile with the country.
