Hi there

Been reading these forums a while but never posted.

Hoping someone can help here: been given an old Toshiba 40XF355D to see if I can try and get it to work right. The issue was that it was getting intermittent rainbow lines on just one side of the display (far right side).

I unplugged the cables going into the t con while the TV was unplugged, gave it a blow and plugged it back in and nothing was resolved.

I jiggled the cables a bit while the TV was still on and the whole screen went blank. I turned it off and on again and now I get a lovely rainbow display of colours across the whole screen.

Is this the sign of a bad T con? Did I kill it completely by jiggling the cables while the TV was still on?

Should I attempt to change the t con or just strip this for parts? Someone on eBay local to me is selling a T con for £7 that I can pick up.

Any assistance would be greatly appreciated!

So for any one else that has this full screen rainbow issue - the T Con card resolves it. The original lines I had came back so the issue probably wasn't the t con until I wiggled the wires and killed it.

The issue with the rainbow colours on one portion of the TV was solved by smacking the TV metal frame gently. You have to remove the entire bezel to be able to slap it properly. It's been working past 3 hours with no issue now.
