Thomson 28WH403S TV failure 4/5 LEDs blinking / flashing


Standard Member
I have a Thomson 28WH403S TV which does not turn on but instead flashes 4 times, followed by 5 times. I have taken it apart and looked at the rather simple looking circuit boards for any burnt out resisters but can't see anything obvious. Can anyone point me in the right direction? It's not worth taking it to the repair shop but if it's just a resister that's burnt out then I might as well do it.

Check resistor RP185 in the power supply which is a 56k/ goes high.
