I have a sagem hd-d50h g4 tv the tv shows a light to say it is too hot and no longer turns on

I would also take off the back cover and vacuum out all the dust that collects in the fan inside. Give it all a good clean, you'd be amazed how much dust gets sucked in.
When it's all back together, do a factory reset. (in the INSTALL menu).

i think your bulb has gone. i've got one also and thesame light has started showing just before the tv turns on. after searching it seems that this is because the bulb is into its last 500 hours of life. at 8000 hours it stops working. i think its an easy fix (dont need to as mines under waranty by comet) you just need a 0.5amp fuse and a bulb off ebay £100.
