42LG3000 solarisation, tcon or lcd faulty

[london-freddie]

Help needed please, been given this faulty 42LG3000 that was going to landfill.
TV all seems to work fine apart from picture
when first switched on screen is white with a dark shadow around the edge after a few minutes warming up the picture comes on heavily solarised, menus also are same
Removed and refitted lvds cable from main to tcon no change in picture
Anyone experienced this before,
I assume it must be mainboard, tcon or lcd panel, but which one

Looks like two faults.

The solarisation is a known fault due to AS15F (T-con IC failure) - easy to fix with the right equipment.

However the white banding is likely to be a panel tab bond fault that may or may not be fixable.

tv has been on for several hours now with a solarized picture, however picture is now flashing constantly from solarised to perfect picture every few seconds

Thanks for the follow-up, I did not really expect that the banding was caused by bad T-CON, learning something new today.
