I am going to try and check the power cable on mine per Tom Bond's last suggestion. After that I may be done as I have gotten no response from emails since the middle of Sept. Hopefully, he is just busy.

I do wish that I had been offered a deal on the refubs as earlier it would have been a viable option. Now we are looking at moving to the 48 and I would hesitate to purchase anything. My dead Vango may be abandoned in Alaska.

Hyrax,

The way I have cleaned all my lenses since the advent of microfiber has been with a dedicated or new microfiber cloth. I just fog the lens by breathing on it and then wipe. (Remember I am a photographer)

Once when I was an unemployed photographer (a.k.a. camera store employee), just after the microfiber lens cloths came out, my boss took one and cleaned a camera mirror and it did not leave a scratch. Camera mirrors are front silvered and very, very delicate. After that, I have never hesitated to clean any coated lens with one. They will normally even remove fingerprints. I have not had to use any lens cleaning solution in years.

K

Sadly, working in a camera store may be more lucrative than photography these days.

Also, I don't know that I even own any lens cleaning solution any more.

Went through the projector some and found the the factory tech does not seat the connections well. Now the projector powers up but after a few minutes, I get weird wrapping like (see photo) Hoping it is the video or formatter board as I have extras.

Anyone have an idea?

Well boys and girls this is an odd duck. The picture wrap went away after about 45 minutes or so.

Going to do a little burn in and see what happens. Tomorrow might bring something else. It will be a while before I trust it as I have been down this road before.

Wow, it seems crazy that most of your current issues with this machine were due to a loose connection....

and not not even the troublesome one in the design. (between the video and formatter cards) Just a sloppy repair tech. There is a couple of screws that did not make it back from Taiwan as well.

Will check it tomorrow. Tom Bond says that the I may still need to adjust the shims on those boards as they may have moved after the unit got fully heated up and that gremlin may yet raise its head again.

seegs, if you look at the photo at the bottom of page 31 in the service manual you will see the connector I found loose.

The projector had run for several hours. We sat down to watch a show and changed the channel and the picture wrap started again. It is like it is some kind of sync issue but just on one side of the screen.

At least I made progress today. The projector does now power on.

Although i am not putting my tools away yet, the projector has worked all afternoon after adjusting some of the shims.

Tom Bond suggested that I Loctite the screws but i am trapped at home today and can't get to Lowe's for the next couple of days. If it now goes bad, I know where to attack the problem.

Wish me luck.

The real wrench in the system was caused by the factory tech not pushing a connector into the LED board all the way to lock. Then through expansion and contraction, vibration or the travel, the connector was angled in its socket and not providing good connection. I could not even attack the shim issue until I found this. A couple of screws are missing as well.

For any of you that need repair, sending it to the factory seems to be a toss-up with my experience of poor workmanship yet others had a better experience.

Mr. Tom Bond is a credit to his company. A real stand up guy. I would not worry about anything he repaired. Too bad he only does the ones under warranty.

I will update the ongoing status between my travels.

At least I had the Dwin on the shelf as a backup. While the old girl was not as good as a working Vango, she pushed a much better image than a blank screen.

I have dealt with Tom on a couple of warranty issues on the eeColor box, and he was superb in handling my issues both times!

I want establish that this thing is actually repaired and then I will work on the calibration. Maybe a screen shot then.

Don't know how helpful a screen shot is. As a pro photog I know that photographs lie and photographers cheat.

Well we returned from travel and now have another 3 nights of viewing without incident. I will feel better when we get past the three weeks it lasted on last repair.

So much trouble over a badly replaced connection.

We now have another successful week. Last night I had, what I believe was, an HDCP handshake error. Restarted the projector and it was resolved.

Have I ever said how much I hate HDCP?

Hoping that that was a one off problem. I have had that before and usually restarting the system from the cable box (a real Tvio from GCI) fixes it. The problem was that it was doing two recordings at the time so I could not shut it down.

At least the projector is still working.

Well, I have been traveling for the last three weeks and have not been watching. Home now and watched last night and today. So far it has been great. Only problem has been a handshake issue but I have changed my startup sequence so that, hopefully, will no longer be a problem.

Still, I have not put the Dwin away as trust has to be built.

Hope everyone is having happy watching.

Does anyone have ever measured input lag of the Vango ? If it's good, I'll be glad to connect a PS4 to the second hdmi input bypassing all electronics.

Well folks, so far so good. The projector has been working fine. Only one little anomaly, on startup I get a magenta cast across the screen. Then everything goes normal. I am thinking that is some kind of syncing and it only show on startup.

Kevin-
That is good news, indeed. A few moments (30 seconds?) after the startup screen I get a very fast flash of colors across the screen. This sounds similar to what you describe. It doesn't seem like a sync sort of thing, but I really have no idea what it is. I've seen it every time I turn the projector for the past 2+ years - it started after I got it back the first time from Tom. As you said, it only occurs after startup (heat related?) and since it has not changed at all for me over the years I hardly notice it any more.

Thanks Tim,

At least I am not the only one. It really does not seem to be a problem but it is odd. Last maybe a second or so and then everything is fine. It only shows on the picture and not the splash screen.

We use it most every evening that we are home.
