Re: 40" Philips 40pfl4706/f7 Mother board replacement

Hi ion4449

I'm curious to hear if you made any progress with your Philips TV. I have a Philips TV with the same problem, it cycles through the logo screen.

I got it on Ebay and seller told me that it had been replaced under warranty by the retailer who never bothered to pick up the faulty TV. She said that it worked for about 3 weeks before the fault appeared. I am currently setting up a hobby workshop and I haven't looked at the TV yet.

I wonder if you have made any progress with your TV?

Regards

The main board is not turning on the backlight, so the main board is likely at fault. You may find connecting BL-ON directly to 12V using a 2.2k ohm resistor will fix your problem; the screen might flicker a little during boot up but if the TV is displaying video, it should be usable.

can you show me what two connections you are talking about? I see BL-ON but what should I connect that to?
