Re: Toshiba 58L135UC Power issues

Thanks neilc6 for the clarification, C113 is open, D301A/B one of them is faulty (shorten). I will replace the cap and those diodes however at this point not even going to try IC functions or not I wonder better buying a new board? Did I miss something? D201 is ok, so that is a bit of hope...

Re: Toshiba 58L135UC Power issues

Q901? You mean Q301, right? I will check all again but I wonder if this is only a power card issue or something else..since you gave that board on your junk that means you need to get a new one to fix that TV?

Re: Toshiba 58L135UC Power issues

Original MOSFET is K13A25D. I've replaced that with PDPF3N50NZ. Both are shorten. Is that PDPF3N50NZ transistor a good replacement? I know I have to check all diodes, Mosfet and rectifiers anyways.

Re: Toshiba 58L135UC Power issues

Thanks neilc6 for a super quick answer. Is MOFSET PDPF3N50NZ good replacement? Did you finally fix the TV?

Re: Toshiba 58L135UC Power issues

I have same Tv same power board issue apparently but by following Neilc6 post #32 I did not resolve the issue. In fact MOSFET FDPF3N50NZ looks like it’s the wrong replacement dfir K13A25D or Q301. The original is shorten and once replace with FDPF3N50NZ also that got shorten. 3 questions I have at this point: 1. Replacing wrong MOSFET is causing that shorten isssue? 2. Should I start troubleshooting from DC primary everything else? 3. Originally I had same issues as per cperiuta described. Should I better buy a new power card or quit...tv...
