Check all the diodes and check the bottom of the power board for bad/cold solder joints, look closely sometimes they look good but are bad or loose.

external hd Seagate, broken down the +12 volt and USB 3.0 SATA board

by gabri2211

Hi to all 😎
I'm looking for any useful information to repair this interface (I have attached the image).
On this board I read E3215-1215A_4D.
This is the small plate inside the HD enclosure that allows to connect a 12 volt power supply, interface the disk with a USB 3.0 socket and is connected to the HD with the SATA connector.

If any of you have found a burnt or short-circuited component in a circuit like mine, if you have useful diagrams for the repair, or even better a description for the tests at the test points, I would be very grateful.
in particular...

Sharp LC-60LE810UN Lamp Error

by Yanleb

Hi all,

I have this Sharp LC-60LE810UN that stays off and blinks a Lamp Error (1 long flash followed by a short flash, in a loop).

I already confirmed that the first backlight strip has an open LED using a LED strip tester. The other 3 LED strips are fine.

Before tearing the LCD panel apart, I want to make sure that the rest of the TV set is good. I've tested the power-supply/LED inverter board by sending 5 volt to PS-ON, to PNL-POW (that commands power the T-CON board only), OFL and STB pins. The power-supply is good.

I've tried all the key...

Using a 5 volt @ 12 amp switching power supply and two USB doctor volt / amp meter to three IPads on one power supply

by sam_sam_sam

I have been wanting to do this project for some time using a Mean-well switching power supply that I bought at least ten of them that were originally in a device that was abandoned for some reason they were listed new but removed from equipment that was never used

I do not understand Mean-well the capacitor next to the voltage reference ic chip was a brand that is known for failure over time the other capacitors are brand name needless to say it got replaced before I even powered it on for the first time

I used a four USB outlet and electrical plate that is made for...

I need to order some 1000uf @ 16 volt it has to be 8mm in diameter what is a good choice

by sam_sam_sam

Here is the page of capacitors that I can choose from what is a good choice for a FSP 400-60GLC
https://www.digikey.com/en/products/...Xmc1YPJ6BlESoA

I try to use a 565-1664-ND which is a 10mm in diameter unfortunately it will not fit because there are two of them the same size and value and there is no room and they go to two different circuits not in parallel...
