I have a infuriating SSL-2 that I got from France (to the UK), and it seems determined to drive me crazy! The latest reason is as follows:
It was basically a brand new projector that had been stored somewhere for 15 years or more. Therefore, I was surprised when the original lamp blew after about 5 hours. However, the replacement (only used on the low setting) then blew after about one hour. It seemed that the metal parts on the lamp holder might not be conducting well, so I've thoroughly scraped the areas that touch the pins with sharp objects, to ensure that there is good contact. I also rubbed the pins of the next lamp I put in with emery paper. Unfortunately, the next lamp has blown after less than an hour, still on the low setting. I don't think the problem is something to do with the electricity supply in my house, as this isn't happening with the other projectors I use.
The only possible problem I can think of is that the projector is set to 220v, not the customary 240v in the UK, but I didn't think this was significant and would put a strain on the lamps, particularly at the low setting. I believe it may be possible to re-set it to 240v, but it's not at all clear to me from the sticker on the transformer - or the details in the service manual - what exactly should be done to achieve this.
I'd be extremely grateful if anyone could advise on:
a) Whether the 220v setting could be causing the lamps to blow (and if not, what the cause might be).
b) Whether an adjustment to 240v is desirable and feasible.
Thanks,
Adrian
