Re: Hyundai W240D

Hi there

I had exactly the same issue, the backlight came for a few seconds after switching the screen on.
When pressing on the board the backlight stayed on for about 30 minutes.
At first, I thought the caps were dead, replaced them then tried again -> same issue.
Then replaced the Mosfet with stronger ones -> same issue.
I even had the idea to replace the tubes with LED's until I took the micrsocope to check all solders.
I discovered then a small, almost invisible crack on the HV transformer solder pad....
