Hi guys

Trying to fix this TV at the moment due to the screen going black after about 30 secs but still  having sound, so ordered a new invertor board of eBay but its still doing it


Any ideas 

Thanks

Check your 24v supply to inverter board if it remains when backlights go out its fault flo tube/Inverter if not look to Power supply
