    Hello
    In the base there is a charge to the OTVC CW29X308P also a chassis S63B. However, I do not know how they differ. OTVC Is dead (the LED-OTVC is off, the relay does not turn on the degaussing coils, etc.) Voltage + 12V actually about 10V reaches the F-Box from the inverter. There are also all other voltages from the inverter except for + 5V with IC803 (switched on with power signal from the F-Box). On the F-Box there is a power supply. 5V St-by with IC802. They are also nap. 3.3V and 1.8V from individual stabilizers. So I would like to insert the original batch from this TV, the more so because access to memory is difficult. I would also like to ask for some additional suggestions.

    Since there is no original charge for the moment, I will substitute the one indicated by my friend mirex. I knew about this charge writing in my query, but I made a Czech mistake by entering the TV model instead of the letter Z (CW29Z .... I entered CW29X ..). I will write on Monday what next with TV after substituting the only charge from the base.
    greetings

    Hello.
    Do not even impose it because it will not change the damage of your work.
    There is a defective processor on the F-box, and you do not even replace it because you need one with the already programmed flash, nothing will hurt you.
    Either somewhere with such a disassemble acting because Samsung is so far unavailable.

    I substituted the memory indicated by my friend mirex and clean - it did not help. I was in touch with Samsung service - they bet on the F-Box, which is also suggested by a colleague, but this module is not available today, let alone its cost. The customer gave up repair so I think the topic is closed
