    Re: Sony SDM-HS75P

    I had the problem of my Sony SDM HS75P switching oiff & on,then blinking every minutes,& then totally stopped working.No response of power button.

    I opened & checked the power supply - it was ok 4.95V & 12.17 V.
    On further inspection I found U202 defective,which is located just above the crystal,
    on the display driver module,right side of graphic processor.

    Removed the part & installed 470 ohms resistor & 3V zener in series across gnd & 5V.
    the junction of resistor & Zener diode 3V connected to the output. Now it is working fine.The pictures are attached.Any clarification,please write here.

                Sony KDL-46HX850 Can't upgrade/update firmware
                by dkneyle
                Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.

                Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about...
