and the main fuse. Inspect for a missing or broken trace near the diodes Sound but No Picture Indicates a backlight failure. Check the boost converter
After conducting a thorough search, I found that the "Vestel 17IPS12" appears to be a model of a monitor or display device from Vestel, a Turkish electronics company.
This board handles high-voltage mains power. Only attempt repairs if you have the proper tools and experience to avoid fatal electrical shock.
⚠️ Beware of scam sites demanding payment for “exclusive schematics.” The 17IPS12 is old enough that genuine PDFs are shared freely in technical forums.
