Screen Flicker	Can't Post

Beko 32 WLA520 HD.
Hi, When TV switched on screen started to flicker. At first it only lasted for a few seconds and then was OK.
As time went on, every time TV was switched on the period before it corrected its self got longer and longer.
Eventually the screen has now gone black but the picture image can be seen in the background if examined close
up. Have been advised it could be the inverter board, fitted new one but to no avail. I'm stuck now, if anybody can suggest
what else it might be I would be very grateful.
Thanks.

are the backlights off or on when the picture goes off? if off then the screen is croaked as you have already changed the inverter board.

OK. This might seem strange to you but how would I know if back lights are on or off.

you look inside in the back of the screen, there is usually a hole or slot in the metalwork.

Bad CCFL bulb(s).
Go out quite similarly to regular fluorescent bulbs
