Re: Philips Pus 436401/12 flashing backlights question
Yes i did remove one of the small SMD resistor on both ICs to slightly limit the current flow ,my thinking was the new leds may be rated different but did not make any difference so i haven't replaced it as yet .I am thinking along the lines as you, open circuit on the LED- which gives me the voltage fluctuation mentioned in post 1 the heat sinks do seem to get quite hot and i cannot find a data sheet for the TPV101AD chip. Ill test the diode mentioned and try to see if i can make sense of the IC readings.
