There are a few things that can cause this fault, but the most common is the High Voltage Capacitors that feed the backlights going bad. The invertor and power supply are on the same board (Vestel 17IPS01-2)
The caps are on the power supply board and are C355 & C356 (12pf 3kv) and C354 (4.7pf 3kv). If you replace these caps it will solve the problem in 99% of cases.
If replacing these three caps do not solve the problem then it may be easier to replace the power supply board... as fixing means replacing a tiny surface mount chip with loads of legs.
WARNING: The Power Supply/Invertor board can contain LETHAL VOLTAGES even when turned off and unplugged. if you are not sure, Pay someone to do it for you!
