    Xerox XG-91D (Proview)

    I have a Xerox XG-91D, I believe is made by Proview. When I turn the monitor on cold it will stay on for 12-15 minutes, then go black. The led will stay on but no screen, pushing the button doesn't do anything but if I unplug it and plug it back in it will stay on for 2-3 minutes. I suspect power supply, I tore the unit apart and found a chip on the power supply board with the markings BD5A28 (near as I can tell) the one leg is burnt and part of the silicone is missing. I think its a rectifier but could be wrong. My local electronics shop doesn't have a listing for this part. I have goggled, yahooed, and dogpiled. Are those words? But could not find anything about it. I have looked at the part number many times and believe that is the correct number.

    1 can anyone help me with info on this part and any cross reference on it?
    2 When changing this part is there another component that I should look at replacing with it?
    3 What would cause this part to fail? Power surge?

    Thanks for any help anyone can give me

          Philips 42pfl6008s/12 red led comes on for a second and then goes away but 3.49v stay active
          by Malcolma172
          I was trying to repair my tv wich previously had a blinking red led 2 times and it kept going. After shorting the sdm the blinking led changed 5 slow blinks and 3 fast ones wich in the service manual meant error 53 / the fusion chip.
          After I heated the fusion chip with a hairdryer for 5 minutes it started working perfectly but after a day it stopped this time no led blinks even in sdm mode.
          After probing the psu I have 3.49v and for 1 second I have at least 2 12.3v lines active the fusion chip gets warm in that second the led turns on and then the 12v lines start losing power...

          Xerox Versalink C505 bad printing in color mdoe
          by pc_okay
          Hello friends,

          I have a problem with this printer Xerox Versalink C505 , printing perfectly in B&W but bad in color.

          There is a little yellow ghost printing around color print.
          So little text in color is unreadable.

          I already change drum cyan & yellow with no success.
          I try (i think) all avalable calibration in printer menu..
          (black drum is dead but it's not the problem i think)

          I'm not a printer specialist,if anyone has an idea?

          Thanks !...

          Samsung UN39EH5003FXZA won't stay powered off
          by Hannibal_Hector
          Hello,

          Purchased a broken Samsung UN39EH5003FXZA (Version CD01) to have fun fixing. When I first acquired it, I did not connect any video signals and only plugged it into the wall. The unit booted and showed the “no signal” window and I could navigate all menus and change sources. I unplugged it, connected my over-the-air antenna to the coax, powered it on, got the unit to scan the HDTV channels, and I think then the TV self-shutdown with the melody. When I powered back up (melody), it would show the channel selected on the OSD and after a couple of seconds, it self-shutdown...

          MacBook A1707 820-00928-A does not stay on
          by mferna14
          Hi., I am working on a MacBook A1707 820-00928-A does not stay on. It shuts down by itself after about 40~45 sec. The amps it takes is so normal .80 ~ .45 ~ .90 within this span of time & all voltages VCORE CPU core present, the CPU & GPU both get warm & then back to 20v 0.0amp. The logic board is like brand new, not even much dust on it. Upon trouble shooting, I see that 3.3V is always present but when the logic board shuts down 5v also drops to 0 & no CORE voltages present. I checked every single point of the 5v rail, physically nothing seems to be shorted. Any tips will be really...
