View Full Version : Marquee 8000 On to Standby constant cycle.
johnsmith808 10-16-08, 12:06 AM I posted this on Curt's website as well. Just in case someone someone else knows what's going on before I send some boards to Curt.
I just picked up a Marquee 8000 yesterday. I was able to get it running right away. I checked the hour meter and it was under 200.
The tubes sure look like this could be accurate.
However, while carrying the pj upstairs, it bumped into a wall moderately. Nothing was damaged on it.
When I fired it up again, I noticed that on an all white screen, the blue looked stripped. The other colors were fine. This wasn't there when I first turned it on.
I was playing with the menus for around 30 minutes. I got to the option to reset to factory settings. I scrolled down to it, but did not press enter. Then all of a sudden, it went off. There was an error LED, H.FAIL. I couldn't get the pj to turn off, so I had to unplug it. I found out later that there is a reset button I could have used.
From this point on, when I turn the pj on, the fans will turn, then around 5 seconds latter, it'll switch to standby. Then it will switch on again, then standby again, endlessly.
It was suggested that I clean all connectors to the H Board and CLM board. Also, I tried starting it up without the H Board and F board, and same result. I also unplugged the HV leads from the splitter for all 3, and same thing happens.
Any ideas?

An odd problem indeed. Try pulling the front grille off, and see if any lights are flashing on the front of the lvps, it is the box that the power cord plugs into. And see if the fans are turning.

johnsmith808 10-16-08, 09:46 PM Your reply worries me. When the most experienced crt guys call something "odd", it's not a good sign.
I think crt's and me just don't get along. I previously had an XG that would drift constantly. Now I turn on this pj, and 30 minutes later, a problem comes up.
If the picture on these things weren't so great, I would have never gotten another crt after the XG.
Now I'm back for more punishment.
I'm pretty sure I checked what you said, but I'll double check.

johnsmith808 10-16-08, 10:21 PM One thing I do know is that this pj was sitting in storage for quite some time. Yet, right off the bat, it seemed to work well.
I haven't connected anything to it yet. Only displayed the internal patterns thus far.
I did notice that there was a vertical squiggly line that was slowly going from left to right. It was on the menu screens, so only the green was on. I thought it might have been some power interference or something. It went away after a little while. Didn't think much of it.
I was able to get into the service menu with the stock password. I put up an all white screen and everything looked great, no sign of wear.
I took the lenses off and the tubes looked great. I left them off to carry the pj upstairs. When I got upstairs, I cleaned the crt faces then replaced the lenses. When I fired it up again and put up the all white pattern again, I noticed that the blue was horizontally stripped. Imagine 10 stripes of blue, with 10 stripes of a slightly lighter shade of blue. I couldn't figure out what that was all about. I didn't touch anything internally at that point, besides the lenses.
I was playing with the menus more when I got to the screen asking if I wanted to initialize everything. I didn't have the chance to press enter when the screen went black. Nothing responded. That's when I saw the H.Fail led come on. I ended up unplugging the pj. When I powered it up again, the fans started up, then they shut off and the pj went into standby. Then a few seconds later come on again, then back to standby. The crt's haven't lit up since.
Well, that's pretty much all there is to tell. The blue tube thing is the one thing that didn't make sense. How would that happen?
Hello. Unplug Vim and check "mini fuses" (green, resistor look alike..)those are located near multipinconnector (near test pins), those should read 0 ohm. And near those are two 4,7ohm smd resistors, those two act as fuse also (for +-15v lines) if those read more that 4,7 ohm you got something wrong on your VIM.
johnsmith808 10-17-08, 07:16 AM I never thought the vlm would matter but notice what I'm experiencing now.
Okay, something different happened. Up to this point I hadn't connected any source to the pj.
Finally I connected my PC to it via a vga to 5 bnc cable. When I did this, the machine doesn't keep going from on to standby. Instead, it instantly goes to H.Fail and stays on.
Next, I unplugged the H Board and powered it up again with the pc plugged in. The pj now stays on with no H.Fail light. Of course no crt's come on either.
I also unplugged the source from the pj and almost instantly it goes back to the on to standby cycle.
So why would plugging in a source affect anything? It sounds like the H board is definitely the problem, but why would plugging in a source make the difference I'm experiencing?
Edit: The pj will still cycle on and standby with the source plugged in sometimes, but after a few times it will stay on.
Also, I noticed a pattern in the clicks. When it cycles on to standby, it clicks two times with a pause between both clicks. When it stays on, it clicks to times quickly, the after a two second pause or so, a third click happens and the pj then stays on, either with H.Fail with the H board plugged in or no error with the H Board unplugged.
