  1. ROLAND VP-540 Will not power up

    2 dead boards is the only likely outcome. Adam, we really are on your side but i would bet a month's pay that going down that path will not have a happy ending I think that’s a secret 20 years ago, everyone doing laptop/notebook repairs needed a rework oven because NVIDIA turned out a years...
  2. ROLAND VP-540 Will not power up

    2 dead boards is the only likely outcome. Adam, we really are on your side but i would bet a month's pay that going down that path will not have a happy ending I think that’s a secret (although bad multilayer connections typically DO NOT short components that adam found & changed)
  3. Chinese uv printer "Experience"

    None of my business but what did the printer cost, all in? andcwhat is the maximum size? will they provide you IDENTICAL ink when you reorder? or does that adhesion you love become just a fond memory?
  4. Chinese uv printer "Experience"

    Regarding the cleaning before print on multiple pass, do what we do with other printers cut the wire powering cleaning pump & insert either a on/off switch or a 10 minute timer (younorobably have one for bathroom fan & light) BE CAUTIOUS with limiting clenings, ink that “sticks to anything”...
  5. Large format UV flatbed

    Take the motor out & see if it turns “no load” see if it turns by hand out of machine
  6. Wrap removal

    They knew how close itcwas. i can remember campaigns that were decided by only a few votes the candidate was criticized for not “spending it all” THE F LIP SIDE is you keep left over money in a special account for life you can contribute to other races, to a PAC PAY LEGAL FEES you cannuse it in...
  7. Wrap removal

    I listened to ed rollins being interviewed last week. He ran many republican campaigns & ross perot’s 3rd party bid in 1992. HE often talks about “the day after” you know you lost, the volunteers are gone, the little people aren’t getting paid anymore. Dumpsters need to be filled desks need to...
  8. Restore Faded Coroplast, Ideas?

    something like armor all or that stuff that makes oxidized autopaint "look new"
  9. Show Off Your Shop >> FireSprint Shop Tour

    if you use one of those shipping add ins that compare rates between different SHIPPING choices it is necessary. also if a quote is requested. (I AM ANSWERING BASED ON MY EXPERIENCE WITH LARGE SHIPPING CLIENTS. I KNOW NOTHING ABOUT FIRESPRINT EXCEPT WHAT I LEARNED FROM THE VIDEO)
  10. ROLAND VP-540 Will not power up

    i am not sure either. it certainly WAS a winning strategy with calcomps, years sgo & with rolands as new as the sc545-ex. ( i still print on one quite a bit) life was siimpler back then & LSI was more resilient. in those days finding a service manual was a rarity. remember only a few years ago...

    a couple of my guys think it is funny that the garbage compactor is what i felt was worthy of comment. that is because I KNEW YOUR PRINTING WAS STATE OF THE ART
  12. Show Off Your Shop >> FireSprint Shop Tour

    Very impressive. i have helped setup high volume packing/ shipping for clients in the past i have to say i wouldn't change a thing we have installed many cardboard compactors, but, i love the garbage compactor it must save quite a bit of time
  13. ROLAND VP-540 Will not power up

    you could CAREFULLY apply switched power with a constant current/current regulating power supply. i am completely unfamiliar with your model. what are the switched power voltages? 12VDC & 5VDC? i hesitate to give this type of advice, because you can do more harm than good, but, you could apply...
  14. ROLAND VP-540 Will not power up

    your right. while i have fixed a few system boards I WOULD HATE to pay anyone the hourly rate for the time i wasted on this
  15. ROLAND VP-540 Will not power up

    i am curious, what was shorted? Probably the best, most versatile piece of test equipment of the last 50 years was the Huntron Tracker (1000 or 2000) it gave you the ability to go along a power supply buss and it could sense proximity to a dead short. (along with Many other capabilities...
  16. ROLAND VP-540 Will not power up

    for the layer to layer connections, the best thing is to have the board put through one of those ovens the repair depots use for the nvidia chipsets that go intermittent i no longer have access to one these were the best way to do the repair without risk of damage to the board THE PROBLEM IS...
  17. ROLAND VP-540 Will not power up

    There is no shortcut to doing actual troubleshooting. someone needs to tske the service manual, a dvm and perhaps an oscilloscope to decide WHAT IS NOT THERE. no one can tell you with so little info why your machine is dead. take the service manual & verify if all the “always on” voltages...
  18. ROLAND VP-540 Will not power up

    there is not simply one component that fails. you need a service manual (and a bit of EXPERIENCE at this sort of thing) i have often found bad solder connections and "feed throughs" from layer to layer on the boards. damonc21 is probably the expert on these machines, the most important...
  19. Question 8x4 coro (flutes running wrong way)

    I am surprised. everywhere they have those posts to protect gas pumps, etc (every once in a while you get the careless or drunk driver gojng into the frontwindow of a convenience store.) the soda companies and cigarette companies provide these all the time
  20. Question 8x4 coro (flutes running wrong way)

    True enough, but i see them up EVERYWHERE. and my client will resell quite a few of these. with a higherpriced substrate it won’t happen. The whole project will just go away or theybwill purchase elsewhere
