    Hello,

    As in the title, I`m looking for the value of the first resistor in the upper left corner.
    It immediately says that the second line is a torn mesh in the middle of the resistor.

    This may be useful, the colors are not clearly visible in the photo - good luck SALR303-G01 Schematic: Identifying Upper Left Corner Resistor Value

    Can be seen. Brown, black, brown, gold, black. Power above 2W. It`s hard to judge without dimensions.

    The problem is that you can`t read the "multiplier" ... because this part of the resistor has burned out.

    The photo shows otherwise.

    I inserted 10R 5% and after connecting it, it flashed in the ceramic capacitor.

    Could a too small resistor damage the capacitor in front of the switch?

    I still have 18R 5% (measured 18.0R) in stock.

    Resistor rating is likely 10 ohms. And I need a type of varistor. On the board position MOV1. On my board it burned out to be unreadable. On your photo is also impossible to read. I would be grateful if you write it.

    Let me find this photo in archive.
    Board back to owner few days later.

    On this PCB is varistor MOX 431 KD07.

    Hello, I just approached this board, unfortunately it was buried, the resistor should be 100 ohms, can someone explain what`s going on with the stripes, that looking at the standard tables it is 10 ohms, is there any other standard?

    Hello! Also got into repairs. I decided to help. How you helped me by raising this topic. Resistor R11 / 100 Ohm / 2W semistor also needs to be replaced...

    Witam wszystkich. Tutaj też mam podobny problem, potrzebuję tylko jeśli ktoś wie co to za dioda D1, poza rezystorem R11 i MOV1 jest zwarta. Podejrzewam też U4-LNK304. Dziękuję za odpowiedź w międzyczasie Close-up of a printed circuit board with various electronic components, including capacitors, diode D1, and LNK304GN integrated circuit.

Topic summary

The discussion revolves around identifying the value of the first resistor in the upper left corner of the SALR303-G01 schematic. Users report that the resistor is likely 100 ohms with a power rating of 2W, despite some confusion regarding its color bands due to damage. Several users mention that the resistor's value may have been misinterpreted as 10 ohms based on standard tables. Additionally, a varistor (MOV1) is noted to be present on the board, which has also burned out. Users share images for reference and discuss potential issues related to using incorrect resistor values, including damage to other components like capacitors.
