Re: Sharp LC-40LE812E fuses blown
I replaced the C7813 with a 3kV one and now I hear some noise from board (transformer). Imeasured the voltage on the caps C7800A/B => 328V. I desolderd the MOSFET and checked it outside with the component tester. All good.
The C7813 can only blown with a voltage to high? But why?

Did you mean the rectifier and the filter caps? I checked both and the filter caps have a low ESR.Leave a comment:

Sharp LC-40LE812E fuses blown
Hello,
I repaired a Sharp LC-40LE812E TV with the main power board DPS-126CP B.
All fuses blown and the capacitor C7813 (220pF 1KV) was cracked. After replacing both, the TV works again without any problems. After 2 weeks the same problem apears with the same symptoms. What can the C7813 blown again and again?
The schematic can be found [URL="https://www.badcaps.net/forum/showpost.php?p=916483&postcount=8"]here[/URL].
Thanks in Advance
