Normally, a lamp does not have the warranty of the main unit, as it is intended for a certain lifetime (operating hours). In my opinion, this is a normal case of wear and tear. However, as I am not an expert, I recommend that you contact Digitec's customer service or BenQ directly for clarification. They will then be able to suggest a suitable replacement item. PS: So explosion? It can happen that there is a bang. Did the outer casing shatter? And if so, was the main unit damaged?
