Lenovo S145 (GS440&GS540 NMC511 REV 1.0) No power
Hi everyone, this laptop once the PSU is inserted the power led lights up for a milisecond.
PQ206 has melted so the markings are unknown to me.
I need the schematic.
Can anyone help me get this motherboard fixed?
Thanks in advance....Last edited by WhiteWolfHellas; 10-13-2023, 11:29 AM.

Dell Inpiron 3521 (LA-9104P)
Hello, I have a Dell with motherboard VAWOO LA-9104P REV 1.0
I tried to upload a video with the symptom here but it fails to upload, so I will describe what it does.
Pressing the power button makes the fan spin for a second and then stop. The power leds also lights up for a second before it turns off.
I have 19.5V, 3.3V and 5V present, but my spi chip UH6 has 0V.
Following the schematic, I see that PU200 has 19.5Vin as well as output voltages.
Can it be a bad bios chip then?
I have checked the +3VLP and it is present....Last edited by WhiteWolfHellas; 10-07-2023, 02:13 AM.

Re: Toshiba 32AV933G stuck on stby
I just injected 3,3V with my bench PSU to PS_ON and 12V and 24V appeared, so my PSU is OK. The problem is the main board?...

Re: Toshiba 32AV933G stuck on stby
I thought about this too. Do you think the 25Q64 needs programming?...

Re: Toshiba 32AV933G stuck on stby
Nope, 0,0V at PS_ON. Any other idea?...

JVC LT-48K780 firmware update
Hello, I have a JVC LT-48K780
Main board: 17MB211
Panel: VES480UNDS-2D-N12
I have backlight but the screen is black. I don't see any shorts on the panel's long t-con board so does this mean that the fault is in the firmware?

Re: Sony KDL-50W800C BLInk 5 times
Any chance anyone has repaired this T-Con for future reference? What chip goes bad similar to ISL9860?

Did everything you said, nothing changed. Could it be a defective panel?...

The One Connect socket is connected in the main board. The yellow socket connects the main board with the 3-D board if that's what you are asking.Re: Samsung UE65F9000SLXXH
