Keven. I said use of the tables (that come pre loaded in the box) is for compensating for room lighting conditions.

The box is a lut table storage device so to speak. You can create your own tables based on a zillion point calibration and use them.

Moot point now Mark, my projector is dead again 3 weeks after repair.

Worst purchase I ever made.

Have you contacted Tom? This seems like something he could fix. Reprograming or a new user installable board.

I have sent Tom an email. He has been great but not really in the repair business.

I have two boards that I had to pay for and did not need sitting in my house now due to genius decisions at the factory. I don't have any real confidence in the factory diagnosing a problem.

I have owned this albatross for 3 years. It has been broken for 7 months out of that time and is now broken again. Maybe I just got a lemon but reliability is an issue with this particular unit. Customer service from the factory is poor. Repair capability is lacking. Having just spent over $1400 on a repair ($500 of which did not address the problem) I wonder when it is just time to write this off as a highly polished turd and cut my losses.

In contact with Tom Bond. Wonderful guy.

If only I could say the same of his manufacturing partner.

Tom Bond and his colleague in Taiwan are working this.

I am reservedly hopeful even though last time he tried, I had to eat two boards with the manufacturer being less than helpful thus the reservations.

Forgot to add that I had to pay an import duty on the projector when it was returned to me. Not really sure why. I was just giving up at that point.

We will see what happens.

With only a few hours put on the Vango in the last three weeks, due to health issues, methinks that someone did not do a burn in on my most recent repair.

When the repair is $150 and the shipping is $750, one would think that taking 24 hrs to do a burn in would be advantageous. The first repair done stateside had a burn in.

Things to ponder.......

If you paid for a repair and it's not fixed then why should you pay to ship it back to fix what should have been originally taken care of? I sure hope Chillin pays to ship it back and do a proper repair.

Regarding the import duty. The US and Taiwan must not have a free-trade agreement which means there will be an import "tax".

The tax is interesting as they were taxing me on my own gear. The dollar amount was low enough not to try and fight the govt when I just wanted the thing back.

I agree that they should pick up the tab but the question is: will they?

There should be absolutely no import tax. And you can apply to the Treasury Dept for a refund.

To avoid a duty on the outbound shipment to a repai county, the package and paperwork must say return to country of origin for repair. Coming back the paperwork must state something to the effect that the unit is being returned to the recipient after repair. I forget the actual words needed.

Mark,

There may have been a language issue here. It was mark on the return "for Repair." It was not a great amount. I was just further picking nits in my anger.

I have already had contact from the factory thanks to Tom and his colleague in Taiwan. I think that this may be the key to the prompt response although a new person is now the contact point.

Now we will see if they come through on correcting the mistake at no cost to me as that was not referenced in the most recent email.

Kevin

Really sorry to come back and see this Kevin. Hopefully this repair will solve all the problems and won't take half a year.

I noticed today I had dynamic blacks turned on and it had been distracting me for a while. I turned it off and was a lot more pleased even with the lighter blacks but lack of constant shifting. I guess I need to recheck my calibration just in case.

Would the color box help me any here?

According to Tom, they are deciding if they are going to fix it at no cost. The shipping is the big item. If they don't do this for nothing then maybe it is time to cut my losses.

Still the most regretted purchase ever.

Well, they have decided that this is a new problem and will not fix it at no cost. They think it is the video board. They first diagnosed the original problem as the video board so I don't have a warm feeling about their diagnostic ability.

The only good thing is that I have a video card. So if on the small chance they are correct, I can fix it.

This is the worst purchase decision I have ever made.

Well boys and girls we have a picture at least for now. I have the new video board in. So really I don't know if it was the board of just reseating everything but we are in for a burn in.

I will update you on the progress.

Still this thing is more trouble than any other purchase I have ever made.

Thank you. I am thinking about chancing it and go and hang it now. Do you think I am pushing my luck? I still have a formatter board I could install.

At least my video board purchase was not wasted. Unless it was my re doing that problem connection between the video and formatter board.

Methinks I know too much about the innards of my projector.

Is the "formatter board" the one that holds and controls the DLP DMD? If it is, I would avoid changing it out. The last thing you want to do is open up the "sealed" part of the light path and let dust and other contaminants in the light path and on the DMD surface which is something you'd have to do if this formatter board is the one I'm thinking of.

After doing the DC4 DMD swap on my recently acquired Planar PD8130, it's taught me that this should only be done in a clean room. The heavy use of a lens cleaning pen throughout the swapping process was required to make sure there was nothing on the surface of the DMD when the new one went in. Anything larger than a particle of dust can make for a visible "spot" on your image.

Just a few words of warning. I would wait and see if the video board was the only thing causing your issue.

Edit:

After looking at the service manual, it looks like this projector separates the board I'm thinking of into two boards. I'd still wait and see if the video board is the only one that needed to be changed.

This is what the single board looks like in the PD8130/50:



vs the two board approach the Vango has:

They replaced the DMD board when I shipped it to Taiwan after sending a video board and formatter board. I also have the new power pigtail inside that Tom sent me.

The first time is was repaired by Tom in New York, he replace a board. I do not know which one it was.

I would shelf mount the projector and put a ventilated dome around it so no one breathes on it...

maybe something inside is getting tweaking from hanging it.

Please. I meant nothing offensive when I used the the word well. I suspect it is the connection and not the board. I never hung my machine, it was run upright and I wouldn't be surprised if the problem was with the connector with gravity causing the problem after some loosening during shipment.

Seegs. If only Heath Kit was still around and you could build your own projector. You would have made a great FP stack or blend EVERY BOARD modified CRTer.

Mine has been mounted upside down since new which will be four years in December with no issues. Luck of the draw to some extent on a mass produced item. Or any item. You have borne up well. My compliments.

Thanks everyone.

Today's update. I had the projector on for several hours yesterday. The only problem that i say was that when we were watching a show, over just a couple of seconds, it flashed first yellow and then some cold tints and a variation of luminance it what looked like steps. The picture then returned to normal and worked that way for at least 20 minutes.

I will check to see if Dynamic Black is set. Could be a problem there in combination with what is coming in on HDMI. We were watching TV so the cable signal could generate confusion in decoding. I would be more worried if we had been watching BluRay. We will watch movies soon and I will be looking for any problems there.

I ask about the inversion because there is one connection in the projector that is problematic. Tom had me check this one in some earlier trouble-shooting and sent me a new spacer to try. The connection is between the Video and Formatter board. Even though there are screws holding each board in place, the connection may not be solid and can cause problems.

Mark, I took no offense. I am getting pretty good at replacing the boards though. I like you wonder if the connection was not made well. I did not try that option since I had a new board. I guess I should have. After replacing the board, the projector buzz is lower much like I remember it being originally. (Knowing full well that or memories are sometime faulty) This whole process is comically frustrating.

If I was not so stubborn, I would have given up by now.
