    Bush DLED32947DVDHD dead!!!

    Hi all any help if you can please. My tv dvd combo has died on me. I have check voltage in with my DVM to PSU and confirm 240v. I have no red power indicator light on the front and the set is unresponsive.

    Does anyone know what voltages I should be getting out of what pins on the 28pin plug to main board? Or what else I should be checking for please?

    The PSU is a Vestel 17PW25-4

    Many thanks
    Craig

      Since it's a 25-4 PSU, check the fuse on the input (little red cylinder) for continuity (with power off.) Do you see any signs of burning around the heatsink on the primary side of the PSU?

              Hi F900 fuse is ok and there are no signs of burning on the primary heat sink? Any other ideas please?

                  R907 is not proving continuity does somebody have a diagram to show what resistance this should be reading please?

                  Thanks

                          Please upload pictures of your board. There are many different versions of it

                                      HI all. Just a note for anyone that has one of these TVs.
                                      Make: Bush (China)
                                      Model: BLED42FHDAE.
                                      Symptoms: Half screen went dark, then tv wend dead. No power lights. Fuse checked ok.

                                      First thing checked was standby 5v: Present @ 5.1v.
                                      PS_ON signal from main board: Present @ 4.5v.
                                      I suspected the power supply to be in a foldback / crowbar condition after the screen going out, so I disconnected the power to LED Backlight board (Part ER643). Now standby light is on and TV responds to remote power on - light goes green.

                                      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...

                                      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.

                                      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...

                                      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...
