Vivo Y12 service is totally dead because there is a short circuit in the vph_pwr line and after it turns on it turns out that there is a short in the light path which also causes the LCD image not to appear

here I am just a novice technician who is still self-taught
if my words in the delivery and explanation are still many mistakes and shortcomings I apologize 🙏
