I 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.

Hi All! So I got this LC-70LE650U monitor from work.... Worked great there! When I got it home and hooked it up I got this split/greenish display problem. Sound works great but nit the display. I tried two different computers and two different HDMI cables and no go. I opened it up and reseated each cable etc and I still have the same issue. I attached images of the boards inside also. Any ideas? Joe...05-31-2024, 06:38 PM

by gregor13Hi everyone,
I'm reaching out for some help with a problem I've encountered with my HP Elitebook x360 1040 G6.
I recently noticed that my computer wasn't powering on. After a bit of investigation, I discovered a burnt component on the motherboard. Unfortunately, I'm not entirely sure what this component is, and I would greatly appreciate any assistance in identifying it and determining if it can be replaced.

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 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 PhotoYesterday, 11:35 AM

by OmronI have a 5W lamp on 12Volts battery, I want it to be half as bright, so I will add a resistor. What resistor should I supply?
A = W = 5 = 0.416mA
_ _
V 12
R = V = 12 = 28.84 Ohms (R) this is resistance of lamp
_ _____
I 0.416
So I will add one resistor 28.84 Ohms
I will have 28.84 + 28.84 = 57.6 Ohms
Or 28.84 + 28.84 = 14.42 Ohms
I don't know if it will work in series or in parallel
voltage would be 6V and amp current mA = 0.208mA We divide everything by two
W= V * I...06-04-2024, 01:58 AM
