Hello, I have an Emerson LC401EM2F which had a blown fuse, searched on here and found it to be a diode that was bad. Changed the diode with the recommended part and that corrected the fuse blown problem. But all I am getting is a click as soon as I plug the tv in and that's it! I also get another click when I unplug the tv. Tv does not power up, no lights, not anything but a click. Anyone have any ideas what could be going on?

Re: Click When Plugged In?
Try to locate the source of a click. A relay is sometimes found on LCD TVs which can cause this clicking sound.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hi there, i am currently diagnosing my corsair rm750 that wont turn on, after a power trip.
Before the power trip, previously i need to push power button on my pc case quite a bit in order to turn the pc (and power supply on), however after the power trip now i cannot turn the pc on at all and i opened the power supply, and found out some of the component(s) are blown. (picture attached)
My current diagnostic is that the (schottky) diode marked "SF" in the 5Vsb circuit are blown and possibly the ES1DF diode too.
Can anyone help me identify the component... -
I've got a shorted SB390 diode which was in parallel with UF5408 diode.
d1031 = uf5408
d1035 = sb390
service manual pages 1-14-25 & 1-14-26
Ive found a equivalent for the SB390 in the SB3H90
what i wanted to know is it likely that the UF5408 has already been replaced?
As in originally both diodes would have been SB390s
So if i were to replace the pair could i replace both with SB3H90?... -
Due to some moisture the VGHP/HVS1 line shorted and this diode D8 blew. The picture is there. It just fades in after some minutes and is quite solarized. Updates again take minutes.
Any idea what Dioide to use? Thx.
Many thanks... -

Schottky blew on dc in. I repaired the traces, replaced the diode, checked diode mode, and tested with no batt. Powered on just fine first time. For good measure tested all the other passive components that lead to the power IC and all seems fine. Tested with battery and the battery is now charging, adapter is recognized, but the battery charges only 2% per 20 mins or so. Urf. Gave it time since it could have been sitting for months for all i know.
Same slow charge rate. Replaced the power IC since it's visibly in line with the exploded diode... -
Hello, I am looking for help to replace a damaged diode. The tristar was replaced and a diode was damaged in the process. I have a picture of the diode but dont have an exact donor. I mostly have macbooks for donors and only a few ipad and iphone boards. Diode part number: DSF01S30SCAP
Im not sure where to find the ipad board number. Anybody have an idea where else this diode is used on other boards? Thanks....
