Sylvania LD320SS8 LCD TV, Repaired

A Sylvania LD320SS8 LCD TV came into the shop that would turn on for a few seconds and then turn off and go back into standby mode. This type of failure is often caused in LCD TVs by the inverter board failing or a bad CCFL. After testing the CCFLs and the components in the inverter section of the inverter/PSU board I found a HV transformer in the inverter section location T1100, with an open secondary coil. Watch the videos on youtube for more info. Have a great day and remember you can always email me john@preher-tech.com with any questions.
