  • Re: samsung LN-T3253H no picture red standby light

    I ended up finishing up the repair successfully. MOSFETs checked out OK.

    Removed all burned glue, replaced the 0.22 Ohm 1W Fusible resistor (RM801) and the 2.2nF 1KV Ceramic cap (CM810), and system powered up just fine.

    Thanks to all

    I still don't know for sure what will be better to replace the 0.22 ohm 1 Watt Fusible Resistor. Digikey has in stock 0.1 ohm, 2 watt and 0.47 ohm 1/2 watt values, and that's about it.

    But I don't want to risk safety. I believe the two 0.1 ohm in series is the best option (rather than two 0.47 ohm in parallel). Unless, the value is not that critical, in which case, I can probably go with a single 0.1 ohm.

    Thanks in advance for any opinions!

    Thank you. That's where I normally order for small quantities. But while Digi-Key have many parts, the 0.22 ohm 1 Watt Fusible Resistor they do not carry in normal stock for small quantities, and I don't see other sources for that value.

    Again, my thought is to substitute two 1/2 watt 0.47 ohm versions in parallel, but I'm not sure of the safety implications if just one of them blows. Alternatively, If I put two 0.1 ohm 1/2 watt, or two 0.12 ohm 1/2 watt fusible resistors (which Digi-Key does have) in series,...

    New to the forum.

    I have the Samsung Model LN-T3253H manufactured December 2007.

    All of the electrolytic caps looked good (no visible leakage, or swollen tops), but with over 8 years on them, I replaced them all as a quick 1st level fix before finding this thread.

    There was burned glue under the in rush current limiter DSC 5D-15 (NT811S) and the top pads looked a little corroded (greenish). In circuit value measures 7.6 ohms. I suspect that is OK, but am not positive.

    The 2.2nF...
