by NicktronicHi all, just curious if the BL_ERR signal is active high or low? TV has the 6 blink error code and I've changed the backlights as they tested questionable (4 strips tested - 203VDC, 203VDC, 203VDC and 175VDC). The new strips all tested at 175VDC. Now when I turn it on, it tries twice to come up and then the 6 blink code. During the this time the BL_ERR pin is high and drops low momentarily, then does it again on the 2nd try to boot (so Im assuming active low). The other thing is the backlight voltage ramps to ~280VDC from around ~160VDC and then back down as the TV tries to boot again. Does...06-03-2024, 07:30 PM

I have this inexplicable problem from yesterday
Each time i start my laptop by pushing the physical power button in, the laptop keyboard and touchpad are available to me for use when the system has booted to the desktop (I can enter the bios by pressing on F10 too) irrespective of whether the laptop is powered by the AC adapter or the battery. This is normal behaviour
BUT NOW FOR THE ABNORMAL PART
However, when using the laptop normally, if i choose restart from the power options, the touchpad and mouse are non-functional when the system has booted to the...06-06-2024, 10:35 AM -

I started troubleshooting this Razer Blade 15 laptop DA560 motgerboard a while back, due to some shorted 19v, 5v, 1v power rails. I fixed some of components and think 19v rail is good, 5v rail is good, 3v is better but not all way i think, and 1v is still bad. At this point the diode reading on these rails are 19v - 0.032v , 5v - 0.167v, 3 - 0.63v and 1v - 0.005v .
When the rails when down, I went down different rabbit holes and seeing chips getting pretty warm on thermal but not blazing hot. Yet there were not any caps or any small components getting blazing hot. Example is EC chip,...1 Photo06-06-2024, 11:35 AM -
by abajorI have this 1707 with the 5V 0A power loop issue on 3 of the jacks.
One of the CD3215C00 had corrosion under one side U3100 to be precise.
This USB jack was drawing ~.2A and not boot looping.
After replacing the CD3215 I am having an odd problem. I can rotate the USB-C and it only works in one orientation. And now it boot cycles, like the other usb channels so I'm part way there.
After looking at the schematic and board view. It makes very little sense that this is happening since they both pin 59 and pin 60 both go to the same places on J3300.

by gjgibHi again guys. I have this motherboard that won't show display even tho it was doing it yesterday. I think something could've past away in the circuit.
I'd appreciate if anyone who is used to MOBO LCD voltages and circuits could enlighten me since this is the first time I have to deal with it.
I'm missing [B]+3VLCD.[/B]
