On initial power up, it takes 3,4 (this morning about 8!) power cycles to get rid of the fuzzy screen you see in this picture. Then, it comes on still fuzzy but readable. After a little time it clears up, but still intermittently (1,2,4 minutes ish) goes fuzzy or blinks completely out and back.

I didnt see any similar issues posted but hopefully someone has some ideas ....besides my idea that its the video board?

I can narrow it to the signal TO the monitor, as a few monitors have all done the same, including the OEM CRT.

Anyone willing to try my video board? I may try to x-ray it at work and maybe run it through the cleaner. My day job is at a large Pick/Place machine builder and we have a great lab for inspecting boards.

IDeas? Or someone has seen something similar?

Thanks as always,
Scott

I've got a VMC 15 with 88HS control and ran into similar issue. Found bad connection in main cabinet at the card cage. Looks like a co-ax cable that plugs into video board. My board was on far left.

Had the same thoughts dougputt.....Had the board in and out several times and messed with the connector......

Will try a few more today in the hopes I can run this weekend .... should have a board to try Monday (should have had it by UPS yesterday, darn) from another shop. Hoping not to lose the whole weekend. If the test board doesnt take care of it i suppose I try a CPU...hmmm.....well thanks I will keep this thread updated

So now, I have had every computer board in the control tested by I-T-S and some "repaired" and the backplane motherboard replaced. So the video, CPU, computer interface, and motherboard.....ALL "tested" and I have the SAME darn issue!!

I have been puring so much time and money into this, maybe another measly 100 wouldnt hurt to try the video cable itself.

There is nothing left? Gremlins? Any ideas at all? THis is crazy its been month after month trying to get this machine working.

[dougputt]

Have you checked in the pendant itself? I imagine yes, but when my machine was shipped to me, during transit one of the video boards had shaken loose (no lock washers)

Anyone want to try my cable?...............

I have installed a new monitor (LCD flat screen), and have tried a few monitors during the debug process all of which do the same thing. Now I have this one temporarily plugged into the wall outlet.....

So somehow I will try to check condition of the cable, I am not sure if this style bullet connector (into the video board) is available at radio shack so I may have to "bite the bullet" and try a new cable...I see them for $108 at fadalparts.

But it kills me to spend that on a cable when i dont see how that can be the root of all this evil.....I have had it connected and disconnected dozens of times so connection isnot an issue. And a signal IS going to the monitor since it goes blank when i disconnect it.

hmmmmm..........who wants a VMC15XT?

darn.....my usual overly optimistic self starting to get worn down by this one!

If anyone wants to try my cable and boards, I will pay you for some time and shiping cost. I am at the end......

Well for an update here, I accidentally figured out a way to power up and actually run my machine!

I reset all the memory as carbide reccomended to someone else with the same screen (I also saw the same memory error).

If I power up, as before I still get the fuzzy screen. But let it sit a half hour or so, power cycle again and I can get a video signal.

Still suspect my CPU board (which I-T-S had "tested").

Well for now I seem to be able to run it with this workaround, at least until whatever is "going" is done and gone.

[dougputt]

did you get the issue resolved on the screen?

[zcases]

Dougput - mannnnnn it drives me nuts....NO! haha, still have the issue. It kills me because I feel it may be one of the boards I already paid to have tested and supposedly repaired. But to send them all back again for a $50 hit per board just to test (againnn) is just .... bothering me. So I keep running with the blinking and fuzzy text..... I know its a risk that it will completely die soon.

Heck, I will send boards out if someone could swap them for a quick test. The keyboard board is the only one not tested yet. It really does seem like a loose connector issue as you stated, but jeez, I have had these in and out multiple times, including the entire cage.

So for now I continue to run on borrowed time. Hope something can happen before my 6 month warranty runs out on the boards that were "repaired" (with no difference).

[dougputt]

i can send you a spare video board if you want to try it?

[denmar]

try this: save all the programs, parameters and backlash,fixture and tool tables; at the enter nex command type : G0 (enter) G0 3000 (ENTER) go to second screen and hit #5 a couple times (if you want to clear the memory) and then hit #2 to restart; or go to page #3 there is a video test.

[zcases]

Dougputt - I will get my video board info/specifics tonight.....

Denmar - interesting for sure - try this tonight as well

Thanks guys! Talk later
Scott

[zcases]

Denmar - at the "enter next command" it will not accept a G0 (zero).........

I also tried it from an MDI screen with nothing happening....

(?)
Thanks
