Hello, I have an lcd from an e scooter which works but has missing segments and I was wondering if there is a way of bringing the missing segments back please?

Check that the missing segments are being properly driven:

Also clean up the solder splash from the traces. -
I’ve checked for continuity between the pins and the chip they’re go to and all the pins have continuity but how do I check if the segments are being correctly driven please?Comment

Find out which pin corresponds to the faulty segment and compare the voltage against good segments.Comment

Board had no history of liquid; unsure of drop history, but no signs of damage of any kind worth noting.
Charger sitting at 5v/0a. PPBUS is at 1.9v-0.9v steady cycle (peaks, drains, loops). Confirmed CHGR_EN_MVR is missing, but DCIN was reaching ISL just fine, so replaced ISL--no change at all. Confirmed pp3v8_aon is also missing--and being unsure *exactly* which signal appears first (or if they are simultaneous), I inspected PMU/U8100 area and found no shorts, but also found PP3V8_AON_MPMU_ISNS_VIN missing (not shorted). Replaced U8100 just in case (have had them fail in weird ways),... -
Hi everyone,
I recently acquired this card from a seller who was selling a PowerMac G5 for parts. He mentioned that the video card was probably broken too.
Upon closer inspection, I can tell the reason why it won't work: it's missing a bunch of CAPS! (it's also missing an inductor - 1.0uH).
It's a nice card as it's one of the few AGP cards that will support 2560 x 1600 resolution on a PowerMac G5 using a 30" Cinema Display.
Looking at the card, it appears to be missing the following:
1x 1.0uH inductor - orange square
2x... -
Hi Everyone. First official post so fingers crossed I conform and also manage to get photos to work.
So I am requesting some help from anyone who happens to have one of these motherboards to hand and perhaps a multimeter.
My board has a single row of header pins for all the front panel stuff (have seen others where they are grouped together differently so thats no help) and the two pins for the power on switch had been previously repaired and I am trying to make a better repair. There looks to be pad and trace damage and im happy to relocate the header pin/pins to...06-24-2024, 01:24 PM -
Hey guys.
Need help with this one.
Fan not spinning due to missing PWN Fan signal.
Also 5 seconds from powering up it freezes, unless in BIOS.
But as soon as Windows starts to load, it will freeze.
CPU is COLD / Room temp when it freezes.
I've replaced the CPU, same problem.
Replaced SIO/KBC IT8987e and reprogrammed - same problem.
Replaced fan - same problem.
Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
Checked the Thermal sensors around CPU and Board to the SIO/KBC and...08-19-2024, 05:22 PM -
Hello, I search this connector (oxydated).
It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?
Do you know how to find this connector please ? What is the exact name for find it ?
