SOT 23-6 marked as 7MH.....what it could be?

12-21-2023, 06:19 PM

I am trying to repair a modeling railroad decoder because rear light remains glowing.

It's connected to a really tiny SOT23-6 chip that is marked as 7MH. Any idea what it could be? (it's a LaisDCC decoder).

Thanks in advance,
Francesc.

A photo of the PCB might help to identify the IC.

Reader PocketBook InkPad 3 – identification of a black component marked 'CT' on the microUSB line

by Maniackk

Hello,

Device: PocketBook InkPad 3
Mainboard: XRZ_E091_PB740-VTTOA-V1.1 / 2017-10-12

I'm replacing the broken microUSB connector on this e-reader, and during inspection after desoldering, I noticed a loose black SMD component marked "CT". One of them was torn off along with the pad, while the other one (marked in the photo) is still in place.

I would appreciate help identifying this component.

Measuring the loose component with a multimeter gives 5.84 MΩ in both directions, while the one still on the board shows no measurable...

Satalite TV decoder - Smart card issue

by harshana

I own satalite TV connection. My Decoder Not functioning well. I was able to find same model decoder from a friend but the thing is My smart card not working on that device.
When I talk with the Service provider, They told me that The decoder Im trying to use will not work on my card because it has a different serial number.

when I replace Bios chip of my new device with old chip it returns and error saying incorrect information.

I have no idea to do anything. No model number mentioned and I can share photos if needed. also I can share bios bin file if you...

Diode marked as "E57".........not able to find it by reference

by Francesc V.

Hi:

I have what it might seem a zener diode. It's marked as E57, but I haven't found any reference that might match my observations.

I've took one from the same circuit and tested isolated with the power supply and a 1k resistor. with 10V, the possible zener stays at 6.6V.

It seems a SOD123 package. It measures (2.6mm x 1.6 mm).

Any idea? it's a 6.6V zener?
