    Help with Phillips Philips 150B power supply issue!?

    Hey Guys,

    Newbie here not too sure if i even have the this post in the right section. Just posting in regards to my LCD monitor (Philips 150B) internal power supply. I'm pretty sure the Caps are dead. The power led blink every 6 seconds and use to take 4minutes to fire up.. Latest boot time was 45mins lol

    Now what I'm wanting to know is. instead of replacing the caps (because im kinda cbf and don't have $$$) am i able to use an old PC PSU? if so could you guys give me a hand with the pin outs?

    As i wont be needing the back light part of the standard PS because the LCD now resides on top of my old OHP to serve as my Ghetto Home Theater projector lol

    Here's where I've got to so far:

    Pics of standard PS



    Help with what needs to go to BRI, P-ID and obviously what needs to go to ON/OFF? im pretty sure i know where the other pins go to lol


    And the PSU which i have prepped kinda to use. Which is from a fairly new compaq desktop which i scrapped for parts. psu tested working.


    Any help appreciated.

    Cheers in advance

    Richie

      The connector in this pic goes to the mainboard right?

      If so, connect up the GND, 12V and 3.3V lines to your ATX PSU and see if it works.

      "ON/OFF" and "BRI" are inverter control signals (lamps on/off and brightness) coming from the mainboard. As you're not using the inverter part anyways, you should be able to just leave them disconnected. What P-ID is.. no idea
      Could you trace where it goes on the PSU board?

      PS: A lot of people on here don't like externally hosted pics. Much less externally hosted pics posted inline.
      Personally, I don't mind as long as they're not on a known malware hoster like imageshack, but to not piss off some of the gurus on here, next time when you post something, click "go advanced" and then "Manage attachments" (below the post editor)

          Cheers Scenic for the reply.. I have already connected voltages and grounds.

          P-ID goes to the same places that BRI and ON/OFF go so I'm guessing its for back light control also? Picture is of traces for BRI, ON/OFF and P-ID.

          Am to try it as soon as i get home.

          Thanks again and sorry about the externally hosted pictures.

                  by Soulzink
                  Hi everyone,

                  I am trying to fix a samsung washinmachine power supply main board.
                  I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
                  Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
                  The power supply board reference is the following: DC41-00189a
                  I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel...

                  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.

                  by KYBOSH
                  I have a floodlight-security camera that recently died on me.



                  its hardwired to 115v po115v outlet. One evening it simply died. After some troubleshooting (ensuring it had power and ensuring the electronics were actually functional by supplying 5v via usb port) i realized the power supply must be the issue. The supply was noticably warm to the touch even though it was not powering anything.

                  Trying to understand what i was up against i went looking for others with similar issues and anyone who might have attempted a repair. While a few ppl have had the...

                  by Cookybaby
                  Hello Everyone, this is my first post and I am excited to be a part of such a great community. I've been reading these forums for awhile and there really is some good friendly people here. No bashing and being rude like 90% of other forums Ive been to. Lets get to the good stuff.

                  I have two years of college in Electronics Engineering Technology. Ive been tinkering with electronics sine about 1990. I know enough just to be dangerous, so be gentle.

                  Model: UN60ES6500FXZA
                  Power Supply P/N: BN44-00525A

                  Samsung Plasma TV Power Supply Issue
                  by lp20th
                  I have a vintage 2008 Samsung 50” Plasma TV, Model code PN50A550S1FXZA with a power supply part number BN44-00222A. I repaired the power supply board several years ago finding a couple of cold solder joints on the back side of the board and it's worked great up until now. Recently a fried sound occurred with the smell of burnt electronics and the TV shut down. Trying to turn it back on yielded the typical relay clicking with no TV boot up. Upon investigation, removing feeds to the other boards within the TV it was found that disconnecting the logic board from the power supply allowed the...
