Dear Sir, My LG TV 32LS3500 does not show even standby power LED. In Power PCB have 340Vdc at main capacitor. Vcc of the IC FSL106HR is at 10Vdc. What will be the problem?

You have to check every voltages in secondary side and mother board voltages.

@@eleclab2096 It says STBY 3.5Vdc must present with the secondary side. But it is 1.58Vdc. Is it due to a malfunction of the Vfd Optocoupler?

I interchanged the Optocoupler. But the voltage is still at 1.58Vdc. There are two SMD IC 2GBH and 1P3. What are those?

I found that one of the ICs in SOT23 labeled as 2GBH is burnout. It is 3-pin IC SMD. How can I find what it is?

ඔයාගේ TV power supply board එකේ සිට mother board එකට යන voltage check කරන්න. ඒවා නියම අගයන් තියෙනවාද? voltage value ඉහල පහල යනවාද බලන්න. ඉන්පසු pas on voltage සහා Bl on voltage බලන්න.
