    Information on original IBM 5150 PC power supply?

    I was wondering about the internals of the original IBM PC power supply, and figured the people here might be able to fill me in. Did it use the TL494? What topology did the PSU use? It was made by Astec, right? Does anyone have a schematic? (Probably too much to hope for.) I've searched the web, but couldn't find much information except it was 63.5W.

    Thanks,
    Ken

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
      by JimBanville
      The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
      Opened it up and discovered the power supply is making a faint clicking or ticking sound.
      I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
      I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...

      Russound CA4 Power Supply Repair
      by CMCM
      Hello Everybody,

      Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

      Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

      The outputs marked 12v and 20v are all measuring only 1v.

      The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

      The capacitors physically look clean (no bludgesor leaks) and...

      Power supply Manson NTP-5561 (5661) LCD controller dead - PIC18F87K90 HEX dump required
      by Andreas_de
      Hello!

      i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
      Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.

      Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?

      Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
      by shamsudeen
      Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
      I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

      i know that in linear power supply the noise will be very low comparing to SMPS supply....
