Beko main board XLX190R-4
PSU FSP312-2m01
Inverter LC370WX4
Tcon LC370WX4-SLA1

Fault set has sound and backlights are on and nice and white
But no picture caps on invert were swollen so replaced
Fuse on tcon was open replaced now have 12v both sides but still no picture

Anyone repaired one of these Tcons or have circuit
It has an TPS65161 buck boast chip fitted and VDD seems to be at 0v which is from transistor Q5 marked L7x3b (note the x has a line under it) it does nor read correct and is the only one on the board
anyone know this device ?
