Bush DLED32947DVDHD dead!!!

[WALTO TDI]

Hi all any help if you can please. My tv dvd combo has died on me. I have check voltage in with my DVM to PSU and confirm 240v. I have no red power indicator light on the front and the set is unresponsive.

Does anyone know what voltages I should be getting out of what pins on the 28pin plug to main board? Or what else I should be checking for please?

The PSU is a Vestel 17PW25-4

Many thanks
Craig

Since it's a 25-4 PSU, check the fuse on the input (little red cylinder) for continuity (with power off.) Do you see any signs of burning around the heatsink on the primary side of the PSU?

Hi F900 fuse is ok and there are no signs of burning on the primary heat sink? Any other ideas please?

R907 is not proving continuity does somebody have a diagram to show what resistance this should be reading please?

Thanks
