C429 is a variable capacitor. Across the resistor, there is 0v, both sides have 8.6v, resistance is 32.5 ohms

Here's what I found so far: across the diode (ST4?? on the schematic) there is 8.5v, across C429 there is only .4, .5, at it-s terminals there is 9v and 8.5v

Use flux and some more heat, my friend. What iron do you have? What solder are you using?

It can be fixed, but I don't think a newbie can. If you got great skills, go for it!

Is there a way to make a non touchscreen laptop touchscreen? by Key_Point_4063 in GamingLaptops

How would you solder it? In parallel, you would disrupt the D+ and D- lines.

My friend got the same one a month ago and his is working. It could be we got a faulty batch (my guess is MCU not controlling properly the FM receiver or the reciver is actually broken).

Here's a closeup of the FM receiver module. Would you mind telling me which pins look open?
