Likely t-con, it's rare for repeating vertical lines to be caused by a panel failure.

Ok,
I had it in with a failed as15 chip
replaced chip twice and both times have had this ...

Posibbly bad batch of as15's

or has something else also gone on the tcon board

Good thing i didnt strip for parts yesterday..lol

So a replacement chip solved the problem?

No,

I had it with a faded screen
replaced the as15 twice
but this proble with the lines persists...

You've tried cleaning and reseating cables?

Re: Samsung 40m86 Vertical lines bad tcon or panel

AS15 wouldn't cause this. Doubt dirty cables would either. Likely a processor fault on the T-con -- maybe the RAM or BGA soldering. I think the M86 has an advanced T-con -- I can't remember if this model has the 100Hz interpolation stuff.

Gone into storage till a tcon comes up at a reasonable price.
might try relfowing the board if I get time..
but otherwise will update once i have access to a replacement tcon.
Thanks for all the input
