    Digistar LC-4010D Dead

    I didn't take any measurements went straight to the power supply which is of excellent build quality. I found the main filter cap (Jainghai 450v 150uf) cover bowed out but it still measures ok on my esr meter. I meant to cut the plastic off to verify if in fact it is venting but ran out of time. I know some caps have a kind of raised cover but this shouldn't look like this should it ?

          Try pressing the disc down. Will it go down?

              Will try in about 4hrs at work atm. Does anyone manufacture them this way ? Would sort of defeat the purpose of getting a visual indication...

                  The plastic cap is insulation. Prevents a single fault insulation failure from electrifying the chassis. I doubt the manufacturers care...

                      The large filter cap had 165v across it but I replaced it anyway. Later I pulled back the platic cover over the top and the top of the can was perfectly flat. Nothing wrong with it.

                      However there was a 22uf 50v cap nearby that tested funky in and out of circuit. Replacing it brought the tv back to life.

                          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...

                          Problem

                          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                          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.

                          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...
