Hi @carlos57 ,
+
+
Did you try uninstalling the touchscreen in Device Manager and then restarting the laptop and let Windows “find and reinstall it” again, you didn’t say?
+
+
I don’t have a touchscreen laptop, so I’m not sure if touchscreens work in safe mode or not, but try starting the laptop in [https://www.digitalcitizen.life/4-ways-boot-safe-mode-windows-10|safe mode] and check if it works OK.
+
+
If it still doesn’t work then here’s the [https://download.lenovo.com/consumer/mobiles_pub/yoga730-13ikb_hmm_201810.pdf|service manual] for the laptop.
+
+
Go to p.46 to view the necessary pre-requisite steps and then the procedure to remove / replace the LCD panel. I can’t find the pinout for the EDP cable but it may be worthwhile to check that the cable is securely connected at both ends, in case the touchscreen wires in the cable are at one end of the plug and it is not inserted fully into the connector etc.
+
+
If it appears to be OK then all you can try is to replace the LCD module. On p.59 Item #2 you’ll find the part numbers for the two LCD modules that are available for the laptop. The touchscreen and LCD screen are one complete module and not two separately replaceable parts. You may find the part number printed on the back of the LCD module itself, if you wish to verify that you have the correct part number.
+
+
If you search online using the ''part number only'', appropriate to your particular laptop, you’ll get results for suppliers of the part
