Hi,

After 2 years of happy use my Evo 1.1 just went pop with a poof of smoke rising out of the top. I've never had any other issues with the unit.

I don't know if this is just the bulb blowing but there's now no power at all to the unit now.. I've checked other power cables so it's not the fuse in that.

Anyone had any experience of this and what I can do to fix the problem?

thanks
J

The eVo will not power on at all? Do you see any LEDs light up when turned on?
Page 22 of the User Guide gives some basic troubleshooting info.

no, no lights, no power at all. as mentioned there was a brief bit of smoke above the unit (presumably coming out of the back) and burning smell, but i don't know what's inside there to know what that might be.

i've used it very regularly and never had any problems before, in 2 years.. but my lamp life shouldn't be due to expire as there was no degradation in the picture and i can't have used 6000+ hours in 2 years.

I could probably get someone to look at it to see what's blown, but I'm keen to get it fixed soon so just wondering if anyone knew any likely components that might burn out like this. I do have a few electrical items running off a quad-plug strip, so I guess potentially I could have spiked the electricity somehow.... but like I said this hasn't happened before.

thanks

As you're eVo doesn't power on, I'm guessing it's more than just a faulty ballast.
You probably won't get any help from LL so I'd recommend taking it to a professional repair person to have them poke around in it.

Yeah, LL ran out of resources to support the eVo. It's unfortunately a product which just about put LL under. Not enough profit margin, and too high a failure rate.

I figure that the most likely thing is still the ballast, and maybe it took the fuse with it. I'd check the fuse first, just because, but with a puff of smoke, that's not likely to be all that happened.

At one time I was looking to buy dead eVos, but I haven't even looked for a while.

my friend has taken a look.. apparently it's the small coil transformer at the front of the unit near the lens, next to a big black capacitor.... left of the yellow "CARLI" component in this picture ...



any idea what this is so I could replace it? i think i'd need a specific item... eg he said he'd probably need to know how many turns the coil had

also this fuse has blown T4AL250V.. i'm not sure if I have a spare but presumably it should be easy enough to get hold of?

also however, looking at the bulb there seems to be some white residue inside and no filament crossing from one side to the other... is there a solid filament normally? or is there nothing connecting the two ends of the bulb inside?

thanks

The lamp is an arc discharge lamp, so there is no filament.

This isn't the "normal" point of failure for an eVo, so you might want to look for another "dead" one. Lots of spare parts then.

does anyone know what the exact part I need is to replace that blown transformer in the previous image...?

also is this bulb blown? i'm guessing it is but how do i tell exactly?



thanks for your help

A soldering iron and some solder wick should be enough to replace the part.

The way to tell if an HID amp is blown is to try it. If it fires up, it's not blown...

HID lamps work by having an electrical arc arcross a couple of electrodes. It's "blown" when the electrodes are too worn to be able to create or maintain an arc across them. Given that you can't just inspect the electrodes, you connect it to a known good working ballast. If it fires up, it's good. If it doesn't then it's not... Unless the fault is the ballast.

but i can't try it because the projector power is dead...

thanks anyway

sorry what i meant is what is that part and where do i get it from? can i just replace the coil part or do i need the whole board it's sitting on?

it costs me $70 to ship even a dead factory-stock EVO1.1 to UK, so I'm a bit hesitant to try and get anything other than just parts

thanks

I'd think that you'd only need the part. unfortunately without a part number or schematic, it's really hard to say what that part would be. If you remove it from the board, there may still be a readable part number on it.

Alternately, you could buy a spool of fine bell wire, and try re-winding the core, but that's not likely to be time or cost effective.

Check the back of the circuit board. If the leads appear to be okay, then it's probably good, and only needs the one componeent replaced. As I said, take it out and look for part numbers or specifications.
