    Viewpia LC-32IE21 no start

    So I got this TV for free since nobody wanted repairing it.

    Symptoms: When plugged in the AC, the LED is constant ORANGE, no RED at all.

    What I did: changed all the caps, except the two small ones (22uf 100V, 4,7uF 50V)

    Found this post https://www.avforums.com/threads/vie...e-help.763685/
    but this didnt help me since the fix is for other models.

    After changing the caps the problem remains.

    Here are some pictures. (sorry for the light, Ill do better photos if needed)

    never overlook small caps, they dry up fast wihout showing any external signs.

        Have you checked if the power supply output voltages are stable?
        Check that when you press the power on button the PS ON signal is activated by the main board (goes HIGH or LOW.)
        Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
        For service manual, schematic, boardview (board view), datasheet, cad - use our search.

          I will check the output voltages as soon as I get my meter...

          I changed even those small two caps but no change.

          I get constant orange light from the LED and the TV does not react to any of the buttons.

          I changed all the caps on the power supply board, but not on the logic board (forgot to mention that).
