    Westighouse L2046NV dead Capxon

    Just got a Westinghouse L2046NV 20" LCD . Power light stays green when the LCD is connected to a VGA source, and one can see a dimmed picture, so the backlight has a problem. Opened the LCD see Pic 'LCDall': it has three boards, including a [1] processing board see pic 'GPU' [2] power and backlight board see pic 'PwrBacklight' [3] button board. On the power/backlight board, capacitor C204 [Capxon 220 micF 25VDC 105 degC] is bulging, see pic 'cap'. Failure of the cap has killed the fuse F200 located on the other side of the board very close to C204; this fuse is a very small surface mount fuse marked 'S' meaning I think 4A. Replacing C204 by a 330micF/25VDC/105degC I had and F200 by a much larger wired PicoFuse 4A solved the problem, and the LCD now works.

    The Westinghouse L2046NV LCD is also marked 'CHI MEI Model A201P2'.
    The Power/backlight board is also marked Delta DAC-19M005 DF Rev 00A.
    On the Power/backlight board, the other large caps are CE101 & CE109: Capxon 220micF 25VDC, CE103 and CE104: Capxon 1000micF 25 VDC, CE102 and ?: Taicon 2200 micF 10VDC. Hope this helps.

      How can I be sure that my EC chip is dead?
      by double_DD
      Hi all,

      As the title suggests, how can I be sure that my EC chip is really dead?

      I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

      Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

      ps5 edm-033 dead after hdmi/usb ports destroyed
      by disorder
      hello guys,

      i need help to repair a edm-033 ps2
      history : as always hdmi port and usb ports destroyed after unplugged
      after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
      so i changed it
      now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
      but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...

      i don't see any projection of liquid metal on pcb.

      KingWin ABT-650MM 650 Watt ATX PSU [PCB: SW8835REV:A]
      by momaka
      For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
      http://www.rmac.kingwin.com/products.../abt_650MM.asp

      I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.




      What mostly drew me into buying it is its 2x PCI-E power connectors...

      Finding a dead short component
      by Beton
      Hi guys!
      I searched for the term "dead short" in the forum but no specific thread came up however if I'm just blind and couldn't see the thread talking about this please forward me to that direction.
      So my problem is I don't know how to find the source of a dead shorted voltage rail. Dead short = ~0 ohm resistance.
      I have two VGAs (HD 4850 and HD 4870), both dead shorted to ground on the memory rail. I have the boardview file for the 4870 and the memory rail consists around ~7892346 capacitors...
      I have a bench PSU and if I try to inject voltage the voltage...

      Chieftec GPS-450-AA with dead 20N60C3
      by zunasthegreat
      Hello everyone hope all doing well!
      I have this PSU (GPS450-AA delta oem) around for like 4-5 years and I had it recapped early 2020 or 2021 with mostly UCC KY and Nichicon PW's. The bulk was and still is fine, the original Ltec's were bloated and empty. The previous issue was some major coil whine noise and at times random shutdowns when going idle. Today it started tripping the mains breaker and I think I have dead APFC mosfets (20N60C3). Right now upon checking I have the Q1 and Q3 FETs dead so far and I guess those are responsible for the PFC circuit. The only thing I care is If there...
