: Often caused by a blown main fuse or shorts in the bridge rectifier diodes (e.g., UF5402).
: TV has sound but no backlight.
If blown, check the bridge rectifier and the main switching MOSFET for shorts.
If you are looking to find a specific variant of this schematic, let me know:
: A frequent design flaw involves three diodes in parallel that may overheat and short-circuit. Experts recommend replacing all three with ones from the same batch to ensure balanced current sharing. Low Voltage Output
The Vestel 17IPS62 is a highly serviceable power supply board. By using a schematic diagram to trace the primary VCC startup voltages, checking the secondary Schottky diodes for shorts, and validating the feedback loop, you can resolve over 90% of the failures associated with this board without needing to purchase a costly replacement.
