    Emerson LC320EM2 Dead

    Hello all! This time I have a Emerson LC320EM2 that is dead with no light or any sign of power. I read through a couple other threads here on this model and it seems my tv is a little different. The fuse is good and I visually checked over the caps or anything that might have gotten hot. I also tested the diodes on the hot side and came out good. I did see that they make a power board repair kit for $25 and was wondering if I should just get that but according to another thread on this TV it did not help out the other guy. Does anybody have an opinion on this??

      Well I just removed the board to have a look at the underside and it looks like someone was in there I'm guessing to put that kit in and had way too hot an iron and just destroyed the traces on the board so looks like I need another board now.

          I hate to revive an old thread but since this post I have done about 8 of these TV's and just get a kit and it has always fixed the tv until now. After installing the kit still no power but now high pitch squeal. Just wondering if anybody has a quick answer without going into major diagnostics?

              Question is what components did you replace?
              Did you force the PSU on without the main board?

              Here is what I did to mine: https://www.badcaps.net/forum/showth...hlight=emerson

                      you switched diode D605 twice? or is that a typo?

                              Did you measure all voltage rails when this thing is chirping? I am thinking something is shorted and loading the PSU down.

                                  No, unplugged it right away because i did not want to fry anything. I was hoping somebody might have ran into this before and might see what I missed replacing.

                                      Does it chirp in STBY or did you turn the TV on?

                                          Just plug it in and a very quiet steady squeal. No light on front and TV will not turn on either.

                                              did you disconnect the main board and plug the PSU in?

                                                      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...

                                                      so i changed it

                                                      but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...

                                                      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...

                                                      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...

                                                      Hello, today I'm working on this lovely MSI Raider GE75 gaming laptop which I bought to flip. Unfortunately, I believe the CPU is toast but I wanted a second opinion before I chucked it into my spare parts bin. I will not have most tools with me today as I'm away from my workbench but I have the basics (a good multimeter, a horrible iron, a solid screwdriver, and my trusty thermal cam). I do not have the original 230w charger, but I have a Dell 180w which was sold with the device and reportedly "worked fine for them".

                                                      Specs: I7-10750H, RTX 2060, 32GB RAM (unknown manufacturer)...
