Sagem Axium HD45S Returns to standby/off?

2nd insert: Recently started to go from start up as usual but then carried on to standby. Now it will not even register (red light) when switched on. Very clean inside - no dust etc... New lamp. Basic checks made. Model is the later version of rear projection sets which can be handled by one person... Excellent picture quality.. Shame to scrap... £100 bonus for repair!!!! Conwy area North Wales....
