I bought the label maker at Sam Club a while back for $29.99 it come with 4 cartridges and they had them on sale again for $29.99 again so I bought another one because I was not sure if I was going to able to get it to work on the battery cells that I had planned on using for this particular...Today, 10:44 AM -
by Dan the DogI need to find a replacement for this diode on one of the six gate drivers of a full-bridge IGBT inverter for a servo motor. It has S3 on the package. How can I find out for sure the right diode that I need. I believe it is schottky because it has 0.2V drop across.
The anode is on pin Ve and cathode on pin DESAT on 316J gate driver IC. Also would be nice if anyone had an idea of the purpose it is serving as it is not included in the suggested schematic of the 316J datasheet.

That laptop wont charge I dont know if the charger is genuine.
To investigate further does anyone know about
how the id pin works for this model, is it a pullup to plus or a analog voltage divider or a
complete digital exchange.

by JonnxHello everybody,
I have seen a lot of posts about the A2237/A2338 about the 5V not boosting up to 20V issue, but none of them seem to have the exact problem as my board does.
My PPBUS_AON was measuring ~9.32V and the board kept power cycling, so I removed the fuse F5200 to measure PPVBAT_AON_CHGR_REG and indeed it was still 9.32V, but the board stopped power cycling. Then I measured U5200 values and got this:
U5200:
PPDCIN_AON_CHGR_R = 5.144V
AUX_DET = 1.287V
VDD = 2.767V
VDDP = 2.767V
AUX_OK = 0.848V
AMON = 0V

Hi everyone!
Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.
My issue: No backlight.
Model: QE82Q70RAT
Type No: QE82Q70RAT
The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.
So hopefully, I can fix this cheaper.
