Hi Shaun,

Thanks for the guidance on this. I managed to find a schematic diagram of the CUC3800 chassis online, with this I was able to locate the parts quite easily. Visibly all the parts look fine. The circuit board slides out and I was able to view them from underneath. All looked ok except for TDA8140 which was all brown coloured at all soldered points. I'll get a photo of this after work and post it. I am going to get my hands on a multimeter tomorrow and perform some further testing.

regards,

Malcolm.
