My beovision LX2500 has for the past six months every now and then shut itself down to standby. It occur quite often, some days every five minutes or even more often and some days it runs for hours without trouble. I am a bit concerned about the safety of running the TV. I have seen some pretty nasty wounds on television PCB’s when something has gone wrong and suspect that there might be a risk of fire. Can it be considered safe to use the set or should I avoid using it?

I would get it serviced - I agree that I too would be concerned.

Television fires are usually caused by accumulation of dust and overheating. But anyway you should get it repaired sooner than later - if nothing else, for the safety of the set itself. Now it could be a matter of redoing some solderings and replacing a few caps, but if the fault goes on long enough it can cause wider damage, including charred PCBs which will make repairs difficult.
