No display, RTD2136R getting hot on the motherboard
After I replaced my PCIe networking card, the display stopped working.
The laptop still booted, but the display didn’t show anything, not even the backlight.
I opened it up again and recorded it with a thermal camera, which showed that the chip called
`RTD2136R` at the top of the motherboard (next to the LDVS connector was over 80°C). That chip is used for LDVS translation, so it makes sense that the screen isn’t working if the chip is broken.
I wondered what the best approach to testing other components would be before I order a chip that won’t be of use.
I can’t see any visible damage on the board, and I cleaned around the beforementioned chip using IPA, but to no avail.
Any suggestions on what I could try and test will be much appreciated.
