ccfl to led conversion for 32pf9531 10 me6 version

crwdns2934249:0crwdne2934249:0:

	i asked philips and their service partner for support but no help and they said it should not be done

	but i did it anyway (again*)

	the me6 version has a 295v power supply for the ccfl board

	the backlight brightness adjustment does not work at the moment so the total power consumption is 42 watt

	[image\|3321790]



	backlight off (1M63 connector pin 1) or led driver board disconnected (1319 connector) power consumption is 35 watt

	[image\|3317811]



	VBLON for 5 volt is connected to 1M63 (card reader pin 2) on the audio standby board

	[image\|3317792]



	for 24 volt ( pin 1 - 5 ) and ground ( pin 6 - 10 ) i used the 1319 connector on the power supply

	pin 13 ( VDM ) on the led driver pcb is connected to the connector 1D42 ( pin 3 ) for reducing the power consumption from 72 to 42 watt but does not change when in tv settings ( contrast brightness ect.) get changed

	[image\|3317791]



	[image\|3321792]



	since it was connected to the ccfl board under the power board

	[image\|3317790]



	now i am thinking to try and modify the backlight brightness adjustment with another circuit ( made over 20 years ago a simple alarm system ) with a photo resistor for automatic dimming but not sure how to limit the voltage 0 - 5 volt depending on the light condition in the room

	*i have done (2016) a ccfl to led conversion on a 32wl66p toshiba tv with 24v power supply it was much easier (analog adjustment for dimming 0 - 5 volt same for backlight on) than this but now the lcd panel is broken dont know if the panel in philips is compatible with the toshiba tv firmware

	*i have done (2016) a ccfl to led conversion on a 32wl66p toshiba tv with 24v power supply it was much easier (analog adjustment for dimming 0 - 5 volt same for backlight on) than this but now the lcd panel is broken dont know if the panel in philips is compatible with the toshiba tv firmware
