Hi all Did a search on the forum but couldn't find any info relating to this. Does anyone know what the expected lifespan is of the bulbs in the Tosh 42WH36? I have had mine for about 10 months now and it is being used a damn site more than I first expected (about 18 hours a day). Also anyone know if these things are easy to change yourself? Or is it an engineer visit? Cheers Hank PS If anyone is interested, my on/off switch is also stuck in!
