Hello,
We have this set here in our shop that is not ginving sign of life besides red light that is blinking one time after pressing the button and nothing more... After detaching the mainboard from the PSU (this set has separate board thank god?! or not...) the backlight comes on. After reattaching nothing besides red light.... Can anyone from the forum help me here? Thank you in advance. Here's a link with images of the mainboard and the memory IC's that are on it.
Regards, Norbert!...

by chth96I usually tried to find datasheet which contains Maximum ESR value like KME datasheet.
[URL]https://www.westfloridacomponents.com/mm5/graphics/S06/KME250VB10RM10X20LL.pdf[/URL]
As far as I know,Maximum ESR means boundary ESR value for bad capacitor.
But,In many case,there is no ESR value in datasheet like below links.

by Kambi13Hi all, need some help, I've got a Lenovo V14-IIL that as total of 8GB of RAM (4GB onBoard - 4GB Sloted), out of the blue it stopped posting, After investigating, found out that removing the RAM stick from the slot, the laptop would post and work with no other issues. So tried with a different RAM stick suspecting that the original one somehow died, but to my frustration the issue remained, so again tried a different number of known working RAM sticks with different capacities and speeds but with no avail.... Unplugged Battery, removed CMOS battery,Reset and Updated Bios, also measured voltages...Today, 05:23 AM

[FONT=Arial]The Balance Pot has to be set at about 30 degrees (11 o'clock) to the left for the output to be balanced (see photo). I'm using an oscope, sig gen 1kHz sine, 8 ohm dummy load).[/FONT]

by ProttHello, my apologies for reviving this thread. I have a 8gen NUC with a (possibly?) dead bios - the fan starts up, slows down, but it doesn't show any picture (recovery button doesn't work either). The dump is attached.

by ATS-ByronHi All,
I tried two different power adapters.
On the lines that are marked as 20V on the boardview, I only have 5V. But there is no light that comes on at all when this think is plugged in.
Customer stated that it just stopped charging and then when the battery died that was it.
I have a suspicion that it could be U7303 which I believe controls the voltage setting for the adapter? [B]Markings are RD LYBK CVEB[/B]
Any help would be appreciated!Hi All,

by Keshenatech1Does anyone have a schematic or parts list for a ZWS150BAF-12 12V power supply? I have a dead one and I've determined the surface mount diode on the back side of the board that connects from the center leg of Q3 to the + side of the 420V 60uf capacitors has a 3.5 ohm short. I'm not having much luck trying to identify the diode as the part number is not very legible. In the attached picture, it's the black rectangular diode in the center. There are some numbers on it but I can't even tell if it's right side up or upside down. The picture is from a 2nd good working unit which is more legible...Today, 08:58 AM

by Super360Hi as you can see from title, I have a samsung tv here that will show the smart tv logo and then no picture after that even hitting input or menu on remote and shows nothing but the backlight still appears to be on. The tv will turn itself off after a minute or so automatically. I'm somewhat confused if this is either a eeprom problem or a bad led strip problem. The power supply makes a pretty noticeable humming sound when it's turned on leading me to believe one of the leds are shorted but idk honestly. Any of you guys have any help for me? I have a good multi meter and can take pictures of whatever...4 Photos04-13-2024, 10:05 PM
