help! - my LP750 has gone pop!

[InsideUsAll]

alright guys

I was at an outdoor party about three weeks ago, and one of the generators was playing up, resulting in one of the projectors I was using going pop :(

so my question is does anyone have a power supply for an infocus LP750? or know where I can get one from? I took it into the local infocus dealer, and they quoted me a ?500 to get it repaired. Think they're aiming at big companies who have got money to throw round, not a struggling v.j who isn't even covering his costs!

any advice or info welcome.

cheers

LOL @ not geared to help VJs

No sympathy, Thats like saying garages arent designed to repair cars for kids who cant drive. You should never have been hooked into a suss genny. I suspect you have realised that.

Going pop is a broad term,
If the voltage dropped to the projector, theres a possability that the voltage regulator dropped out depending on the ps design ( at a low voltage the field effect in the transformer is reduced, potentially increasing the current capabilitys) so a pop at lowered voltage can be a totally flashed out scrapped unit.

On the other hand if the voltage was rising you could have the regulator colapse and other problems including the loss of an optic group through a bulb bangin.

Short answer, You dealer isnt tossin you off, The cost of repair is lower than Id expect, What the fuck where you thinking off? Only a lunitic hooks kit they can't afford to lose into a suss Genny.

The owner of the genny had best have insurance, or was this a typical playing for the sake of the ART learning curve?

Rules of the game.. The person who hires you is responsable for provision of a clean mains supply, However that dosnt mean you leave you brains in a Jar and hook in if the mains is suss. Its better to cancel and remain the proud owner of your projector than be an artistic hero with a pile of scrap.

I hope your gig was worth it, cause thats the last gig outta your projector without spending heavy money to get it back to being reliable.

Sorry if this sounds harsh, but you have just provided a perfect example of how not to do it, If theres even a possibility of the equipment suffering, its shutdown time, Even if you get a mains spike, or a glitch, turn it off,

The resulting blank screen always looks better when its by choice.

lets get this in perspective.
A projector isnt a PC, it isnt modular and is sure as fuck isnt something that you open at home and just drop and new supply into. Since it runs on HMI bulb technology, it should be bench tested after a professional repair and a fresh PAT test cert (or equivilent) granted by the repairer to declare it safe.

If you manage to get it going but it catches fire in the middle of your next gig, You'd be VJ popular,

Take it on the chin, youve been an idiot with this machine once already, take it to the shop and avoid doing it twice. there are too many safety factors involved.

thanks for the lecture G. I was hoping for some valuable advice, or info from anyone who has knowledge of where to order a replacement power supply from, not somebody to have a go at me.

I don't know who you think you are, but I happen to know quite a lot about what I should be plugging into what & when, having been a qualified computer vision engineer for many years. I don't feel the need to get into an argument about who has most experience, as my ego doesn't need the boost yours seems too.

I choose to take risks with my equipment because of my love of the music & the parties I perform at. Every now and then you have to pay a price for these risks. You may or may not be interested to know that nobody has insurance at the parties I work at, infact no money changes hands at all. I work in the free party scene in Psy trance & techno in the south of england. I find when no money is involved everybody who attends is there because they love what they do, especially the artists. These parties knock the socks off any money grabbin club.

So yes, I may have to take this one on the chin, but I was hoping to get a any advice I could on the cheapest way to do it before I spend any cash.

Next time you decide to lecture someone remember anonimity can work two ways. And please try not to assume you know more than the person you are talking to on a forum, these threads are here to help, not patronise.

not all 700 members have your background. If you wish to post in a manner that suggests it cool to just drop in a power supply and one of the newwbies followed your example,,,,, I think the tone of my reply covers it.

Agreed that post should be helpful. your is helpful as an example of why not to plug into a dodgy genny.

You sentiments re free partys are your own choice, so is the destruction of a projector for the sake of one free show.

I have no interest in a war of words, You goofed, others can learn from it.
you asked for advice on the subject. mine was blunt. but also relevent.

N why the *&^K dos the word EGO keep commin up?

self inflicted costs didnt have any relevence to ego last time I looked.

You already know your dealer, and you attitude against anyone else making a living sux.

I happen to own a club, and could also give you a few good reasons why No insurance is insane.

Lets not confuse EGO for a responsable attutude.

Hey thanks for the tips 'n all, but I managed to fix my LP750 for the grand old cost of ?1.58 and a few hours work. All that had blown was a capacitor & a fuse inside the power supply. So I'm a happy bunny again now.
