Hi,
my 7590 spontaniously rebooted and showed "workshop mode press ALT-F" in BIOS post, then worked normally for two days, after shutdown a few hours later is dead and doesn't power on.
After a few hours of measuring I didn't find anything obvious, although the 2.5 Ohm measured might be too low, but I never fixed a notebook before (only other things like TV power supplys)
Found the boardview cad and schematics in this forum.
Voltages +1VALW, +3VALWP, +5VALWP, B+, +SDC_IN, +3V_PCH are ok

I have an Asus X540ubr laptop of my customer.
The problem is it's not powering on.
When I check,all the voltages are ok.
I tried heating the motherboard with my soldering iron,after that it started to work fine and also charges the battery.
After leaving it turn off for 1 or 2 hours,then it's not turning on back again.
When I heat up the motherboard again,it turns back on again.
What would be the problem of this?Today, 05:57 PM -
Hi guys,
i own an HP laptop that suddenly lost all info in the BIOS (serial number, model number, UUID and so on) and the TPM module that used to work is no longer recognized.

Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
