When I assembled dreamcast I mistakenly fastened long bolt and It resulted in
cutting tiny trace.
This tiny trace(Total width of white coating is 5.5mm) is between R337,R343 and IC101 and it is covered with white coating in the below screenshot.
Firstly I tried to bridging tiny broken trace with my own eyes...But it is totally impossible..So a week ago, I ordered G1200 Digital Microscope and I magnified this tiny broken trace with it.
But It seems that It is really very tiny trace So I plan to order 0.1mm coper wire from aliexpress in order to bridging... -

Hello. I have an Inspiron 7501 here, it's the same as a Vostro 7500 in some markets (no clue). I was looking to replace the LCD, the panels included with these models are terrible.
I have the schematic and it is a 4 lane eDP port on the board but the pinout seems quite weird, my question is if anyone recognises this weird pinout and knows of any other Dell models that may use it or even any compatible panel models.

This make me think that maybe the gpu VBIOS has to be re programmed.
BTW someone already worked on this mainboard. Near graphic board there is Winbond flash memory that I think its stored the VBIOS.
I attach some pictures and one of message error I get when I power on the ... -
The LCD on my Korg KROSS2 keyboard is cracked and needs to be replaced.
However, the cost of a replacement LCD is almost the same as the price of a second hand Korg KROSS!
Does anyone have a copy of Korg KROSS2 Service Manual? I want to see the PINOUT for the LCD connection. Perhaps I can find a compatible LCD screen and not have to spend a fortune on an original replacement LCD.
From what I can gather, the LCD screen is a COG with serial interface (SPI). Is there any way I can ascertain (perhaps with the use of a multimeter or oscilloscope) the PINOUT by...
