hello, everyone I'm not able to open the files with .tvw extension. I have an exclusive boardview for these extensions and even so I can't open it, it says the file is corrupt. Can someone from the forum download and test? thank you

Lenovo Yoga C930 laptop. No charging from usb type C. The reason is a damaged CYPD4226 chip. It gets hot even when the battery is connected. Runs on battery alone as long as it's charged. I desoldered the layout. The resistance on the power supply in relation to the mass measured on the desoldered system is 44ohm.
I ordered such a new chip and hence the question.
Does the chip require additional programming beyond what I understand it should have (firmware) or will it work using information from the EC without programming?
If needed, is there a dump for this chip?
